OpenStack Workload Reference Architecture: Big Data
|
||||
===================================================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
Big Data analytics has established itself as an important process to support
|
||||
new or enhanced business models. Big Data is a term for data sets that are so
|
||||
large or complex that traditional data processing applications are inadequate
|
||||
to deal with them. Big Data analytics refers to the use of predictive
|
||||
analytics, user behavior analytics, or certain other advanced data analytics
|
||||
methods that extract value from data.
|
||||
|
||||
Since Big Data analytics can include and analyze all types of data sources,
|
||||
the results are valuable for most departments in an enterprise. Each might
|
||||
perform analytics with different business objectives. Considering the short
|
||||
innovation cycle of most digital business models, Enterprise IT is often
|
||||
under pressure to fulfill a multitude of demands quickly. A flexible, fast,
|
||||
efficient and easy-to-manage Big Data deployment is critical.
|
||||
|
||||
Cloud is one approach to tackle the dynamic situation caused by high volumes
|
||||
of analytics requests with rapid deployment time requirements. In an
|
||||
OpenStack-based cloud environment, a Big Data cluster can be provisioned in
|
||||
an automated manner. The value of Big Data on cloud contributes to it being
|
||||
one of the top use cases for OpenStack. According to the April 2016
|
||||
`OpenStack User Survey`_, 27 percent of users have deployed or are testing
|
||||
Big Data analytics solutions.
|
||||
|
||||
Apache Hadoop on OpenStack offers a Big Data infrastructure that scales out
|
||||
both compute and storage resources, and provides the secure and automated
|
||||
capabilities for the analytics process. The `Apache Hadoop project`_ is the
|
||||
de facto standard open source framework for Big Data analytics, used in the
|
||||
vast majority of deployments. Multiple Hadoop clusters are often deployed to
|
||||
respond to an enterprise’s needs.
|
||||
|
||||
This reference architecture is intended for enterprise architects who are
|
||||
looking to deploy Big Data Hadoop clusters on an OpenStack cloud. It describes
|
||||
a generic Hadoop architecture and uses open source technologies:
|
||||
|
||||
* `OpenStack cloud software`_
|
||||
|
||||
* `Ubuntu Linux`_ operating system
|
||||
|
||||
* `Apache Ambari`_ – open source software to provision, manage and monitor
|
||||
Hadoop clusters.

This reference architecture describes and includes installation files for a
|
||||
basic Hadoop cluster. Additional services can be applied for a more complex
|
||||
configuration and will be covered in future works.

OpenStack for Hadoop Clusters
|
||||
-----------------------------
|
||||
|
||||
This Hadoop architecture is derived from actual use cases and experience.
|
||||
Building a Hadoop-based Big Data environment can be a complex task. It is
|
||||
highly recommended to use common approaches to reduce this complexity, such as
|
||||
identifying the data processing models. These processing models demand high
|
||||
availability of resources, networking, bandwidth, storage, as well as security
|
||||
constraints in the enterprise context.
|
||||
|
||||
* **Batch processing model** – Analytics based on historic data
|
||||
|
||||
In the batch processing model, the analytic tasks are executed or queried in
|
||||
a scheduled or recurring manner. Typically the data is already available for
|
||||
analysis in a static repository such as large files or databases. The batch
|
||||
processing model is often used to analyze business data of a certain period.
|
||||
One example is an ETL (extract, transform, load) process to extract business
|
||||
data from various ERP systems for supply chain planning.
|
||||
|
||||
* **Stream processing model** – Business real-time analytics
|
||||
|
||||
In the stream processing model, data is continuously streamed and directly
|
||||
analyzed in real time. Actions can be triggered in case of occurrence of
|
||||
special or defined events. An example of a stream processing workload is
|
||||
fraud detection for credit card companies. A credit card transaction is
|
||||
transmitted online to the credit card company and is evaluated in real time
|
||||
based on certain parameters; for example, checking the card’s validity and
|
||||
the purchase amount against the limit. It is also possible to check the
|
||||
location of purchases and compare this to other recent purchases.
|
||||
For example, if purchases are made in the U.S. and Europe in a timespan of
|
||||
only a few hours, this indicates a high likelihood of fraud and action can be
|
||||
taken to decline the transaction.
|
||||
|
||||
* **Predictive processing model** – Predict outcome based on recent and
|
||||
historical data
|
||||
|
||||
This model is used to predict an outcome, behavior or other actions for the
|
||||
future. Generally this analytic model consists of various predictive
|
||||
algorithms. One example is predictive maintenance. Data from machines,
|
||||
engines or other sensors is collected and analyzed so that predictive actions
|
||||
can be made to recommend the next maintenance cycle before a failure might
|
||||
occur.
|
||||
|
||||
Hadoop clusters use a master-slave architecture. The data is ingested into the
|
||||
cluster and stored in blocks in the Hadoop distributed file system (HDFS). The
|
||||
default block size is 64MB. The blocks of data are replicated to different
|
||||
nodes in the clusters. Part of the core Hadoop project, `YARN`_ provides a
|
||||
framework for job scheduling and cluster resource management. With YARN,
|
||||
multiple data processing applications can be implemented in the Hadoop cluster.
|
||||
|
||||
.. _YARN: http://hortonworks.com/apache/yarn/
|
||||
|
||||
Typically a Hadoop cluster with YARN is composed of different types of cluster
|
||||
nodes:
|
||||
|
||||
* **NameNode** – The metadata about the data blocks are stored in the NameNode.
|
||||
This provides lookup functionality and tracking for all data or files in the
|
||||
Hadoop cluster. NameNode does not store the actual data. Generally the
|
||||
NameNode requires high memory (RAM) allocation. The NameNode belongs to the
|
||||
"master" part of Hadoop architecture.
|
||||
|
||||
* **DataNode** – This is also referred as the worker node and belongs to the
|
||||
"slave" part of a Hadoop architecture. It is responsible for storing and
|
||||
computing the data and responds to the NameNode for filesystem operations.
|
||||
Generally a DataNode requires high amount of storage space.
|
||||
|
||||
* **ResourceManager** – This is the master that manages the resources in the
|
||||
Hadoop cluster. It has a scheduler to allocate resources to the various
|
||||
applications across the cluster.
|
||||
|
||||
* **NodeManager** – This takes instruction from the ResourceManager and is
|
||||
responsible for executing the applications. It monitors and reports the
|
||||
resources (cpu, memory, disk) to the ResourceManager.
|
||||
|
||||
An OpenStack cloud is powered by many different services (also known as
|
||||
projects). Utilizing the core services and the Hadoop Common package, a
|
||||
Hadoop cluster can be deployed in a virtualized environment with minimal
|
||||
effort. Optional services such as the OpenStack Orchestration service (Heat)
|
||||
can be added to automate deployment. This reference architecture does not
|
||||
cover OpenStack Big Data Service (Sahara). Sahara provides a simple means to
|
||||
provision as well as scale previously provisioned Hadoop clusters.
|
||||
Sahara will be covered in future reference architecture documents.
|
||||
|
||||
Figure 2 shows the core and optional services in relation to one another,
|
||||
and the services to confirm are available in your OpenStack cloud.

Structuring a Hadoop Cluster with OpenStack
|
||||
-------------------------------------------
|
||||
|
||||
OpenStack provides the necessary compute, network and data storage services
|
||||
for building a cloudbased Hadoop cluster to meet the needs of the various
|
||||
processing models.
|
||||
|
||||
Networking
|
||||
**********
|
||||
|
||||
Multiple networks can be created for the Hadoop cluster connectivity. Neutron
|
||||
routers are created to route the traffic between networks.
|
||||
|
||||
* **Edge Network** – Provides connectivity to the client-facing and enterprise
|
||||
IT network. End users are accessing the Hadoop cluster through this network.
|
||||
|
||||
* **Cluster Network** – Provides inter-node communication for the Hadoop
|
||||
cluster.
|
||||
|
||||
* **Management Network** – Optionally provides a dedicated network for
|
||||
accessing the Hadoop nodes' operating system for maintenance and monitoring
|
||||
purposes.
|
||||
|
||||
* **Data Network** – Provides a dedicated network for accessing the object
|
||||
storage within an OpenStack Swift environment or to an external object
|
||||
storage such as Amazon S3. This is optional if object storage is not used.
|
||||
|
||||
Neutron security groups are used to filter traffic. Hadoop uses different
|
||||
ports and protocols depending on the services deployed and communications
|
||||
requirements. Different security groups can be created for different types of
|
||||
nodes, depending on the Hadoop services running on it. With OpenStack security
|
||||
groups, multiple rules can be specified that allow/deny traffic from certain
|
||||
protocols, ports, or IP addresses or ranges. Each virtual machine (VM) can be
|
||||
applied with one or more security groups. In OpenStack, each tenant has a
|
||||
default security group, which is applied to instances that have no other
|
||||
security group defined. Unless changed, this security group denies all
|
||||
incoming traffic.
|
||||
|
||||
Image Management
|
||||
****************
|
||||
|
||||
There are multiple options to provide operating system configuration for the
|
||||
Hadoop nodes. On-the-fly configuration allows greater flexibility but can
|
||||
increase spawning time. The operating system images can also be pre-configured
|
||||
to contain all of the Hadoop-related packages required for the different types
|
||||
of nodes. Pre-configuration can reduce instance build time, but includes its
|
||||
own set of problems, such as patching and image lifecycle management. In this
|
||||
example, the Heat orchestration features are used to configure the Hadoop
|
||||
nodes on-the-fly. Additional Hadoop and operating system packages are installed
|
||||
on-the-fly depending on the node type (e.g. NameNode, DataNode). These packages
|
||||
can be downloaded from Internet-based or local repositories. For a more secure
|
||||
enterprise environment, local package repository is recommended.
|
||||
|
||||
Data Management
|
||||
***************
|
||||
|
||||
Similar to an external hard drive, Cinder volumes are persistent block-storage
|
||||
virtual devices that may be mounted and dismounted from the VM. Cinder volumes
|
||||
can be attached to only one instance at a time. A Cinder volume is attached to
|
||||
each Hadoop DataNode to provide the HDFS.
|
||||
|
||||
If the data to be processed by a Hadoop cluster needs to be accessed by other
|
||||
applications, the OpenStack Swift object storage can be used to store it.
|
||||
Swift offers a cost-effective way of storing unstructured data. Hadoop provides
|
||||
a built-in interface to access Swift or AWS S3 object storage; either can be
|
||||
configured to serve data over HTTP to the Hadoop cluster.
|
||||
|
||||
Orchestration
|
||||
*************
|
||||
|
||||
Heat uses template files to automate the deployment of complex cloud
|
||||
environments. Orchestration is more than just standing up virtual servers;
|
||||
it can also be used to install software, apply patches, configure networking
|
||||
and security, and more. Heat templates are provided with this reference
|
||||
architecture that allow the user to quickly and automatically setup and
|
||||
configure a Hadoop cluster for different data processing models
|
||||
(types of analytics).
|
||||
|
||||

|
||||
Demonstration and Sample Code
|
||||
-----------------------------
|
||||
|
||||
This section describes the Heat template provided for this workload. The
|
||||
template is used to configure all of the Hadoop nodes. It has been created
|
||||
for reference and training and is not intended to be used unmodified in a
|
||||
production environment.
|
||||
|
||||
An Ambari Hadoop environment is created on a standard Ubuntu 14.04 server
|
||||
cloud image in QEMU copy on write (qcow2). The qcow2 cloud image is stored in
|
||||
the Glance repository. The Apache Ambari open source project makes Hadoop
|
||||
management simpler by providing an easy-to-use Hadoop management web UI backed
|
||||
by its RESTful APIs. Basically, Ambari is the central management service
|
||||
for open source Hadoop. In this architecture, an Ambari service is installed
|
||||
on the Master Node (NameNode). The Heat template also installs additional
|
||||
required services such as the name server, Network Time Protocol (NTP) server,
|
||||
database, and the operating system configuration customization required for
|
||||
Ambari. Floating IP can be allocated to the Master Node to provide user access
|
||||
to the Ambari service. In addition, an Ambari agent service is deployed on
|
||||
each node of the cluster. This provides communication and authentication
|
||||
functionality between the cluster nodes.
|
||||
|
||||
The following nodes are installed by the Heat template:
|
||||
|
||||
* **Master Node (NameNode)** – This node houses the cluster-wide management
|
||||
services that provide the internal functionality to manage the Hadoop cluster
|
||||
and its resources.
|
||||
|
||||
* **Data Nodes** – Services used for managing and analyzing the data, stored in
|
||||
HDFS, are located on these nodes. Analytics jobs access and compute the data
|
||||
on the Data Nodes.
|
||||
|
||||
* **Edge Node** – Services used to access the cluster environment or the data
|
||||
outside the cluster are on this node. For security, direct user access to the
|
||||
Hadoop cluster should be minimized. Users can access the cluster via the
|
||||
command line interface (CLI) from the Edge Node. All data-import and
|
||||
data-export processes can be channeled on one or more Edge Nodes.
|
||||
|
||||
* **Admin Node** – Used for system-wide administration
|
||||
|
||||
Multiple networks (edge, cluster, management, data) described in previous
|
||||
sections are created by the Heat orchestration. A Neutron security group
|
||||
is attached to each instance of the cluster node. The template also provisions
|
||||
Cinder volumes and attaches one Cinder volume to each node. Swift is not
|
||||
configured in this template and will be covered in future work.
|
||||
|
||||
The Heat template, BigData.yaml, can be downloaded from
|
||||
http://www.openstack.org/software/sample-configs/#big-data.
|
||||
Please review the README file for further details.
|
||||
|
||||
Scope and Assumptions
|
||||
---------------------
|
||||
|
||||
The Heat template provided for this reference architecture assumes that the
|
||||
Hadoop cluster workload is deployed in a single-region, single-zone OpenStack
|
||||
environment. The deployment in a multi-zone/multiregion environment is outside
|
||||
the scope of this document.
|
||||
|
||||
The Heat template is configured to address the minimum infrastructure
|
||||
resources for deploying a Hadoop cluster. Architecting a Hadoop cluster is
|
||||
highly dependent on the data volume and other performance indicators defined by
|
||||
the business use cases, such as response times for analytic processes and how
|
||||
and which services will be used.
|
||||
|
||||
The sample environment uses the Java environment. As such, the Heat template
|
||||
installer will be required to accept the Java license agreement.
|
||||
|
||||
As mentioned, Sahara is not used in this implementation. Sahara is the
|
||||
OpenStack Big Data Service that provisions a data-intensive application cluster
|
||||
such as Hadoop or Spark. The Sahara project enables users to easily provision
|
||||
and manage clusters with Hadoop and other data processing frameworks on
|
||||
OpenStack. An update to this reference architecture to include Sahara is under
|
||||
consideration.
|
||||
|
||||
Summary
|
||||
-------
|
||||
|
||||
There are many possible choices or strategies for deploying a Hadoop cluster
|
||||
and there are many possible variations in OpenStack deployment. This document
|
||||
and the accompanying Heat templates serve as a general reference architecture
|
||||
for a basic deployment and installation process via Openstack orchestration.
|
||||
They are intended to demonstrate how easily and quickly a Hadoop Cluster can be
|
||||
deployed, using the core OpenStack services. Complementary services will be
|
||||
included in future updates.
|
||||
|
||||
These additional resources are recommended to delve into more depth on overall
|
||||
OpenStack cloud architecture, the OpenStack services covered in this reference
|
||||
architecture, and Hadoop and Ambari. The vibrant, global OpenStack community
|
||||

Big Data Sample Heat Template
|
||||
==============================
|
||||
|
||||
This heat templates deploy a Hadoop cluster with Apache Ambari.
|
||||
|
||||
Ambari is the central management service for Open Source Hadoop. It provides
|
||||
central administration and management functionality via a web UI. In this
|
||||
example, the Ambari service is installed on the MasterNode and an Ambari agent
|
||||
is deployed on each DataNode in the cluster. This provides communication and
|
||||
authentication functionality between the Hadoop cluster nodes.
|
||||
|
||||
**Type of roles in this Hadoop cluster**
|
||||
|
||||
====== ==================================================================
|
||||
Role Details
|
||||
====== ==================================================================
|
||||
Master Master Node (aka Name Node) - this node houses the cluster-wide
|
||||
management services that provide the internal functionality to manage
|
||||
the Hadoop cluster and its resources.
|
||||
Data Data Nodes – services used for managing and analyzing the data,
|
||||
stored in HDFS, are located on these nodes. Analytics jobs access and
|
||||
compute the data on the Data Nodes.
|
||||
Edge Services used to access the cluster environment or the data outside
|
||||
the cluster are on this node. For security, direct user access to the
|
||||
Hadoop cluster should be minimized. Users can access the cluster via
|
||||
the command line interface (CLI) from the Edge Node. All data-import
|
||||
and data-export processes can be channeled on one or more Edge Nodes.
|
||||
Admin Administrative Server - Used for system-wide administration.
|
||||
====== ==================================================================
|
||||
|
||||
This template provision a small testing environment which demonstrate the
|
||||
deployment of a Hadoop cluster in an OpenStack cloud environment. The
|
||||
default settings used in this template should not be used without changes
|
||||
in a production environment. Users are advised to change the settings that
|
||||
fit in their own environment.
|
||||
|
||||
This template was tested using Mitaka & Liberty release of OpenStack.
|
||||
|
||||
-----------------
|
||||
Heat File Details
|
||||
-----------------
|
||||
This template requires a few standard components such as an Ubuntu cloud image
|
||||
and an external network for internet access.
|
||||
|
||||
The template prepares a few resources that are required by the Hadoop
|
||||
deployment.
|
||||
|
||||
Multiple Cinder volumes are created for the Hadoop filesystem.
|
||||
For simplicity, every node is attached with a Cinder volume with a default size
|
||||
in this example.
|
||||
|
||||
Multiple Neutron subnets are created. This includes:
|
||||
|
||||
================== ======================
|
||||
Subnet Details
|
||||
================== ======================
|
||||
Cluster Network Provides inter-node communication for the Hadoop cluster.
|
||||
Data Network Provides a dedicated network for accessing the object
|
||||
storage within an OpenStack Swift environment or to an
|
||||
external object storage such as Amazon S3. This is
|
||||
optional if object storage is not used.
|
||||
Management Network Provides a dedicated network for accessing the Hadoop
|
||||
nodes' operating system for maintenance and monitoring
|
||||
purposes.
|
||||
Edge Network Provides connectivity to the client-facing and enterprise
|
||||
IT network. End users are accessing the Hadoop cluster
|
||||
through this network.
|
||||
================== ======================
|
||||
|
||||
Multiple routers are created to route the traffic between subnets.
|
||||
Other networks can also be created depending on your specific needs.
|
||||
|
||||
Security Groups are defined and attached to every Node in the cluster.
|
||||
Custom rules can be created for different types of nodes to allow/deny
|
||||
traffic from certain protocols, ports or IP address ranges.
|
||||
|
||||
Next, the template creates a few servers of different roles (Master, Data,
|
||||
Edge, Admin). An Ubuntu 14.04 cloud image is assumed to be used as the default
|
||||
operating system of each servers.
|
||||
|
||||
When the server is booted, additional packages (depending on roles) are
|
||||
installed and configured on each server. In this example, the Apache Ambari
|
||||
is installed and all systems are configured with name server, ntp,
|
||||
package repositories and other necessary settings for the Apache Ambari
|
||||
service.
|
||||
|
||||
The Ambari Web UI can be accessed by pointing to the MasterNode's
|
||||
IP address at port 8080. A Floating IP can be associated to the MasterNode.
|
||||
|
||||
-------------------------------
|
||||
Running the heat template files
|
||||
-------------------------------
|
||||
|
||||
You need to source the OpenStack credential file. You may download a copy of
|
||||
the credential file from Horizon under Project>Compute>Access & Security>API
|
||||
Access
|
||||
|
||||
Prior to running the template, please edit and change the default value of each
|
||||
parameters to the one that match your own environment.
|
||||
|
||||
**Example to setup the Hadoop cluster environment**::
|
||||
|
||||
openstack stack create --template BigData.yaml HadoopCluster

|
||||
The OpenStack Enterprise Work Group is developing a series of 'tenant-level'
|
||||
reference architectures to help users to learn and understand how to deploy
|
||||
different types of workloads on an OpenStack Cloud. These reference
|
||||
architectures describe the list of OpenStack services that can be used to
|
||||
support the various workloads and provide sample code to bootstrap the workload
|
||||
environment on an OpenStack Cloud.

Web Applications Reference Architecture Sample Heat Template
|
||||
============================================================
|
||||
|
||||
These heat templates deploy WordPress on a 3-Tier LAMP architecture. There are
|
||||
two versions of the primary template, one which creates a static environment
|
||||
which does not require ceilometer, and one which provides autoscaling of the
|
||||
web and application tiers based on CPU load, which does require ceilometer.
|
||||
|
||||
|
||||
**The WordPress 3-Tier LAMP Architecture Sample**
|
||||
|
||||
====== ====================== =====================================
|
||||
Tier Function Details
|
||||
====== ====================== =====================================
|
||||
Web Reverse Proxy Server Apache + mod_proxy
|
||||
App WordPress Server Apache, PHP, MySQL Client, WordPress
|
||||
Data Database Server MySQL
|
||||
====== ====================== =====================================
|
||||
|
||||
**NOTE:** The sample WordPress application was tested with CentOS7 and
|
||||
Ubuntu Trusty and Ubuntu Xenial.
|
||||
|
||||
-----------------
|
||||
Heat File Details
|
||||
-----------------
|
||||
|
||||
The template uses a nested structure, with two different primary yaml files,
|
||||
both of which utilize the same 4 nested files. The templates were tested using
|
||||
Newton release of OpenStack, and Ubuntu server 14.04 and Centos7.
|
||||
|
||||
**WebAppStatic.yaml:** If you want a static environment, run this yaml file.
|
||||
This will create a static environment, with two load balanced web servers, and
|
||||
two load balanced application servers, and a single database server using
|
||||
cinder block storage for the database files.
|
||||
|
||||
REQUIRED PARAMETERS:
|
||||
|
||||
* ssh_key_name, image_id, public_network_id
|
||||
|
||||
OPTIONAL PARAMETERS:
|
||||
|
||||
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
|
||||
db_server_name, app_server_name, web_server_name, dns_nameserver
|
||||
|
||||
**WebAppAutoScaling.yaml:** If you want a dynamic autoscaling environment,
|
||||
run this yaml file. This yaml files sets up heat autoscaling groups.
|
||||
|
||||
REQUIRED PARAMETERS:
|
||||
|
||||
* ssh_key_name, image_id, public_network_id
|
||||
|
||||
OPTIONAL PARAMETERS:
|
||||
|
||||
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
|
||||
db_server_name, app_server_name, web_server_name, dns_nameserver
|
||||
|
||||
The following 4 yaml files are called by the primary files above, and are by
|
||||
default expected to be in a nested subdirectory:
|
||||
|
||||
**setup_net_sg.yaml:** This file creates 3 separate private networks, one for
|
||||
each tier. In addition it creates two load balancers (using neutron LBaaS V2),
|
||||
one which has a public IP that connects the web private network to the public
|
||||
network, and one with a private IP that connects the web network to the
|
||||
application network. The template also creates a router connecting the
|
||||
application network to the database network. In addition to the networks and
|
||||
routers, the template creates 3 security groups, one for each of the tiers.
|
||||
|
||||
**heat_web_tier.yaml:** This template file launches the web tier nodes.
|
||||
In addition to launching instances, it installs and configures Apache and
|
||||
Apache modproxy which is used to redirect traffic to the application nodes.
|
||||
|
||||
**heat_app_tier.yaml:** This template file launches the application tier nodes.
|
||||
In addition to launching the instances, it installs Apache, PHP, MySQL client,
|
||||
and finally WordPress.
|
||||
|
||||
**heat_sql_tier.yaml:** This template file launches the database tier node and
|
||||
installs MySQL. In addition it creates a cinder block device to store the
|
||||
database files. The template also creates the required users and databases for
|
||||
the WordPress application.
|
||||
|
||||
-------------------------------
|
||||
Running the heat template files
|
||||
-------------------------------
|
||||
|
||||
First you need to source your credential file. You may download a copy of the
|
||||
credential file from Horizon under Project>Compute>Access & Security>API Access
|
||||
|
||||
**Example to setup the static environment**::
|
||||
|
||||
openstack stack create --template WebAppStatic.yaml --parameter ssh_key_name=mykey --parameter image_id=ubuntu --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network ThreeTierLAMP
|
||||
|
||||
**Example to setup the autoscaling environment**::
|
||||
|
||||
openstack stack create --template WebAppAutoScaling.yaml --parameter ssh_key_name=mykey --parameter image_id=centos --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network ThreeTierLAMP

OpenStack Workload Reference Architecture: Web Applications
|
||||
===========================================================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
Web applications are the most prevalent applications in business today. They
|
||||
are driven by user interaction over the Internet using a web browser front-end.
|
||||
Common web applications include webmail, online retail sales, online auctions,
|
||||
online banking, instant messaging services, and more.
|
||||
|
||||
Web applications are typically characterized by IT resource requirements that
|
||||
fluctuate with usage, predictably or unpredictably. Failure to respond to
|
||||
either can impact customer satisfaction and sales. An automatically scaling web
|
||||
application and underlying infrastructure can be essential. Unlike a
|
||||
traditional, static environment, cloud computing allows IT resources to scale
|
||||
dynamically, both up and down, based on the application-generated load
|
||||
(CPU utilization, memory, etc.).
|
||||
|
||||
The OpenStack cloud platform offers auto-scaling for web applications as well
|
||||
as a comprehensive platform for all IT applications, offering agility and
|
||||
cost-effectiveness. OpenStack is open source cloud software that controls large
|
||||
pools of compute, storage, and networking resources throughout a datacenter,
|
||||
all managed through a dashboard or API. Thousands of enterprises use OpenStack
|
||||
to run their businesses every day.
|
||||
|
||||
Intended for enterprise IT architects, this reference architecture describes
|
||||
the architecture and services required by a simple three-tier web application,
|
||||
using popular LAMP software on an OpenStack cloud. LAMP consists of Linux,
|
||||
Apache, MySQL, and PHP/Python/Perl and is considered by many as the platform of
|
||||
choice for development and deployment of high performance web applications.
|
||||
|
||||
We identify and recommend the required and optional OpenStack services for both
|
||||
a static virtualized implementation and a fully dynamic auto-scaling
|
||||
implementation. Lastly, we will provide tested implementation files you can
|
||||
use to install and instantiate an OpenStack web application environment using
|
||||
Wordpress as the sample application. These files are Heat templates that will
|
||||
create the virtual servers for each tier, networking, load balancing, and
|
||||
optionally, auto-scaling.

||||

||||

OpenStack for Web Applications
|
||||
------------------------------
|
||||
|
||||
A three-tier web application consists of the web presentation, the
|
||||
application, and persistent database tiers.
|
||||
|
||||
- Web presentation tier – cluster of web servers that will be used to render
|
||||
either static or dynamically generated content for the web browser.
|
||||
- Application tier – cluster of application servers that will be used to
|
||||
process content and business logic.
|
||||
- Database tier – cluster of database servers that store data persistently.
|
||||
|
||||
An OpenStack cloud is powered by many different services (also known as
|
||||
projects). Utilizing only the **core services**, a three-tier web services
|
||||
application can be deployed in a virtualized environment that can be
|
||||
**manually** scaled up and down as required with minimal effort.
|
||||
|
||||
**Optional services** can be added for more functionality:
|
||||
|
||||
- OpenStack Orchestration service (Heat project) allows automating workload
|
||||
deployment.
|
||||
- Together, Orchestration and Telemetry (Ceilometer) enable dynamic scaling as
|
||||
load increases and decreases.
|
||||
- OpenStack Database service (Trove) provides Database-as-a-Service (DBaaS) to
|
||||
automate database provisioning and administration. Trove is an option for
|
||||
web applications on OpenStack but is not used in this basic reference
|
||||
architecture.
|
||||
|
||||
Figure 2 shows the core and optional services in relation to one another, and
|
||||
the services to confirm are available in your OpenStack cloud.

||||

Structuring an OpenStack Web Application
|
||||
----------------------------------------
|
||||
|
||||
Generally a three-tier web application consists of a web presentation tier,
|
||||
application tier, and persistent database tier. This chapter discusses these
|
||||
and additional architectural components and considerations for an
|
||||
OpenStack-based web application.
|
||||
|
||||
.. list-table::
|
||||
:widths: 20 50
|
||||
:header-rows: 1
|
||||
|
||||
* - Architectural Components
|
||||
- Description
|
||||
* - Web presentation tier
|
||||
- A cluster of web server used to render static or dynamically generated
|
||||
content for the web browser.
|
||||
* - Application tier
|
||||
- A cluster of application servers used to process content and business
|
||||
logic.
|
||||
* - Database tier
|
||||
- A cluster of database servers used to store data persistently.
|
||||
* - Load balancers
|
||||
- Two load balancers are required to equally distribute load. The first
|
||||
load balancer distributes the web traffic at the presentation tier. A
|
||||
separate load balancer is required to distribute the load among the
|
||||
application servers.
|
||||
* - Relational Database Management System (RDBMS)
|
||||
- The database tier used in this example uses a master/slave RDBMS
|
||||
configuration. Data is kept in persistent block storage and backed-up
|
||||
periodically.
|
||||
* - Firewalls
|
||||
- For security, a set of firewall rules must be enforced at each tier.
|
||||
* - Network configuration
|
||||
- The network must be configured to filter unnecessary traffic at
|
||||
different tiers.
|
||||
* - Auto-scaling
|
||||
- Auto-scaling is desirable to automatically respond to unexpected
|
||||
traffic spikes and resume to normal operation when the load decreases.

|
||||
|
||||
Load balancing
|
||||
**************
|
||||
|
||||
Load balancing can be based on round robin, least connections, or random. If the
|
||||
application is not cloud-native and needs to maintain session state,
|
||||
Load-Balancing-as-a-Service (LBaaS) can be configured to always direct the
|
||||
equest to the same VMs. Neutron allows for proprietary and open-source LBaaS
|
||||
technologies to drive load balancing of requests, allowing the OpenStack
|
||||
operator to choose. Neutron LBaaS V1.0, is used for this reference
|
||||
architecture. V2.0 is available with the OpenStack Liberty release and supports
|
||||
Octavia as well as HAProxy backends. An alternative to Neutron LBaaS is to
|
||||
setup a software load balancer by launching instances with HAProxy.
|
||||
|
||||
Image management
|
||||
****************
|
||||
|
||||
There are multiple options and tools to provide configuration of servers when
|
||||
spawning instances of the web, application, and database VMs. On-the-fly
|
||||
configuration allows greater flexibility but can increase spawning time. The
|
||||
images can also be pre-configured to contain all of the files, packages and
|
||||
patches required to boot a fully operational instance. Pre-configuration can
|
||||
reduce instance build time, but includes its own set of problems, such as
|
||||
patching and keeping licenses up to date. For this example, the orchestration
|
||||
features built into Heat are used to spawn and configure the three tiers of
|
||||
servers on-the-fly.
|
||||
|
||||
Persistent storage
|
||||
******************
|
||||
|
||||
Similar to an external hard drive, Cinder volumes are persistent block-storage
|
||||
virtual devices that may be mounted and dismounted from the VM by the operating
|
||||
system. Cinder volumes can be attached to only one instance at a time. This
|
||||
reference architecture creates and attaches a Cinder volume to the database VM
|
||||
to meet the data persistency requirements for the database tier. In the case of
|
||||
a database VM failure, a new VM can be created and the Cinder volume can be
|
||||
re-attached to the new VM.
|
||||
|
||||
Swift provides highly available, distributed, eventually-consistent
|
||||
object/BLOB storage. Unlike a physical device, Swift storage is never mounted
|
||||
to the instance. Objects and metadata are created, modified, and obtained using
|
||||
the Object Storage API, which is implemented as a set of REpresentational State
|
||||
Transfer (REST) web services. If the web application requires hosting of static
|
||||
content (e.g. image, video), use Swift to store it, and configure Swift to
|
||||
serve the content over HTTP. In this reference architecture, Swift is also used
|
||||
for storing and archiving the database backup files.
|
||||
|
||||
Network subnets
|
||||
***************
|
||||
|
||||
For this workload, Neutron is used to create multiple subnets, one for each
|
||||
tier: a web subnet, an application subnet, and a data subnet. Neutron routers
|
||||
are created to route traffic between the subnets.
|
||||
|
||||
Network security
|
||||
****************
|
||||
|
||||
Filtering of inbound traffic is done through the use of security groups.
|
||||
Different security groups can be created and applied to the instances in each
|
||||
tier to filter unnecessary network traffic. OpenStack security groups allow
|
||||
specification of multiple rules to allow/deny traffic from certain protocols,
|
||||
ports, or IP addresses or ranges. One or more security groups can be applied
|
||||
to each instance. All OpenStack projects have a "default" security group, which
|
||||
is applied to instances that have no other security group defined. Unless
|
||||
changed, the default security group denies all incoming traffic.
|
||||
|
||||
Orchestration
|
||||
*************
|
||||
|
||||
Heat uses template files to automate the deployment of complex cloud
|
||||
applications and environments. Orchestration is more than just standing up
|
||||
virtual servers. It can also be used to install software, apply patches,
|
||||
configure networking and security, and more. The Heat templates provided with
|
||||
this reference architecture allow the user to quickly and automatically setup
|
||||
and configure a LAMP-based web services environment.
|
||||
|
||||
Auto-scaling
|
||||
************
|
||||
|
||||
The ability to scale horizontally is one of the greatest advantages of cloud
|
||||
computing. Using a combination of Heat orchestration and Ceilometer, an
|
||||
OpenStack cloud can be configured to automatically launch additional VMs for
|
||||
the web and application tiers when demand exceeds preset thresholds. Ceilometer
|
||||
performs the system resource monitoring and can be configured to alarm when
|
||||
thresholds are exceeded. Heat then responds to the alarm according to the
|
||||
configured scale-up policy. Scaling can also be done in the opposite direction,
|
||||
reducing resources when the demand is low, saving money.
|
||||
|
||||
Demonstration and Sample Code
|
||||
-----------------------------
|
||||
|
||||
This section describes the Heat templates provided as resources for this
|
||||
workload. They have been created for reference and training and are not
|
||||
intended to be used unmodified in a production environment.
|
||||
|
||||
The Heat templates demonstrate how to configure and deploy WordPress, a
|
||||
popular web application, on a three-tier LAMP architecture. There are two
|
||||
versions of the primary template: one that creates a static environment
|
||||
(manual scaling) and one that integrates with Ceilometer to provide
|
||||
auto-scaling of the web and application tiers based on CPU load.
|
||||
|
||||
The Heat templates can be downloaded from

Heat file details
|
||||
*****************
|
||||
|
||||
The Heat template uses a nested structure, with two different primary yaml
|
||||
files, both of which use the same four nested files. The files contain inline
|
||||
comments identifying possible issues and pitfalls when setting up the
|
||||
environment. The templates were tested using Mitaka release of OpenStack, and
|
||||
Ubuntu server 14.04 and Centos 7.
|
||||
|
||||
**WebAppStatic.yaml:** Run this yaml file for a static environment. It creates
|
||||
a static environment with two load-balanced web servers, two load-balanced
|
||||
application servers, and a single database server using Cinder block storage
|
||||
for the database. This yaml file utilizes Heat resource groups to call
|
||||
heat_app_tier.yaml and heat_web_tier.yaml, launching multiple copies of the web
|
||||
and application servers.
|
||||
|
||||
**WebAppAutoScaling.yaml:** For a dynamic auto-scaling environment, run this
|
||||
yaml file. It sets up Heat auto-scaling groups and Ceilometer alarms for both
|
||||
the web and application tiers. The high-CPU Ceilometer alarms are configured by
|
||||
default to add an instance when the average CPU utilization is greater than 50%
|
||||
over a five-minute period. The low CPU alarms are configured to remove an
|
||||
instance when the average CPU utilization drops below 20%. When configuring
|
||||
Ceilometer CPU alarms, it's important to keep in mind that the alarm by default
|
||||
looks at the average CPU utilization over all instances in the OpenStack
|
||||
project or tenant. Metadata can be used to create unique tags to identify
|
||||
groups of nodes, and then have the alarm trigger only when the average CPU
|
||||
utilization of the group exceeds the threshold. Ceilometer does not look at the
|
||||
CPU utilization on each of the instances; only the average utilization is
|
||||
reported. Another very important tip: ensure the selected "period" used to
|
||||
monitor the nodes is greater than the sampling rate configured in
|
||||
/etc/ceilometer/pipeline.config file. If the sampling rate is higher than the
|
||||
period, the alarm will never be activated.
|
||||
|
||||
The following yaml files are called by the primary files above:
|
||||
|
||||
- **setup_net_sg.yaml:** This is the first file called by the main templates.
|
||||
This file creates three separate private networks, one for each tier. In
|
||||
addition, it creates two load balancers (using Neutron LBaaS V1.0): one with
|
||||
a public IP that connects the web tier private network to the public network,
|
||||
and one with a private IP that connects the web tier network to the
|
||||
application tier network. The template also creates a router connecting the
|
||||
application network to the database network. In addition to the networks and
|
||||
routers, the template creates three security groups, one for each of the
|
||||
tiers.
|
||||
|
||||
- **heat_web_tier.yaml:** This template file launches the web tier nodes. In
|
||||
addition to launching instances, it installs and configures Apache and Apache
|
||||
modproxy, which is used to redirect traffic to the application nodes.
|
||||
|
||||
- **heat_app_tier.yaml:** This template file launches the application tier
|
||||
nodes. In addition to launching the instances, it installs Apache, PHP, MySQL
|
||||
client, and finally WordPress.
|
||||
|
||||
- **heat_sql_tier.yaml:** This template file launches the database tier node.
|
||||
It also creates a Cinder block device to store the database files, and the
|
||||
required users and databases for the WordPress application.
|
||||
|
||||
Scope and Assumptions
|
||||
---------------------
|
||||
|
||||
The Heat templates provided and described above assume that the three-tier web
|
||||
application workload is deployed in a single-region, single-zone OpenStack
|
||||
environment. If the actual application requires higher SLA commitment, it is
|
||||
recommended to deploy OpenStack in a multi-zone, multi-region environment. This
|
||||
deployment is out of the scope of this reference architecture and will be
|
||||
described in a separate one.
|
||||
|
||||
As mentioned, Trove is not used in this implementation at this time. Trove is
|
||||
OpenStack DBaaS that provisions relational and non-relational database engines.
|
||||
An update to this reference architecture to include Trove is under
|
||||
consideration.
|
||||
|
||||
Another OpenStack service that would be suitable for the
|
||||
three-tier architecture would be Neutron Firewall-as-a-Service (FWaaS). FWaaS
|
||||
operates at the perimeter by filtering traffic at the Neutron router. This
|
||||
distinguishes it from security groups, which operate at the instance level.
|
||||
FWaaS is also under consideration for a future update.
|
||||
|
||||
Summary
|
||||
-------
|
||||
|
||||
There are many strategies for deploying a three-tier web application and there
|
||||
are choices for each OpenStack deployment. This reference architecture is meant
|
||||
to serve as a general guide to be used to deploy the LAMP stack on an OpenStack
|
||||
cloud using core and selected optional services. The Heat orchestration service
|
||||
is used; however, popular third-party deployment products such as Chef, Puppet,
|
||||
or Ansible can also be used. Other OpenStack services can be selected to
|
||||
enhance this basic architecture with additional capabilities.
|
||||
|
||||
This document shows how easily and quickly a three-tier LAMP and Wordpress
|
||||
environment can be implemented using just a few OpenStack services. We offer
|
||||
the Heat templates to help you get started and become familiar with OpenStack.
|
||||
|
||||
These additional resources are recommended to delve into more depth on overall
|
||||
OpenStack cloud architecture, and the components and services covered in this
|
||||
reference architecture. The vibrant, global OpenStack community and ecosystem
|
||||
can be invaluable for their experience and advice. Visit openstack.org to get

eCommerce Sample Heat Template
|
||||
==============================
|
||||
|
||||
These heat templates deploy OpenCart on a 3-Tier LAMP architecture. There are
|
||||
two versions of the primary template, one which creates a static environment
|
||||
which does not require ceilometer, and one which provides autoscaling of the
|
||||
web and services layers based on CPU load, which does require ceilometer.
|
||||
|
||||
|
||||
**The OpenCart 3-Tier LAMP Architecture Sample**
|
||||
|
||||
======== ====================== ====================================
|
||||
Layer Function Details
|
||||
======== ====================== ====================================
|
||||
Web Reverse Proxy Server Apache + mod_proxy
|
||||
Services Application Server Apache, PHP, MySQL Client, OpenCart
|
||||
Data Database Server MySQL
|
||||
======== ====================== ====================================
|
||||
|
||||
-----------------
|
||||
Heat File Details
|
||||
-----------------
|
||||
|
||||
The template uses a nested structure, with two different primary yaml files,
|
||||
both of which utilize the same 4 nested files. The templates were tested
|
||||
using the Newton release of OpenStack, and Ubuntu Trusty and Xenial, and Centos7.
|
||||
|
||||
**eCommerceStatic.yaml:** If you want a static environment, run this yaml
|
||||
file. This will create a static environment, with two load balanced web
|
||||
servers, and two load balanced application servers, and a single database
|
||||
server using cinder block storage for the database files.
|
||||
|
||||
REQUIRED PARAMETERS:
|
||||
|
||||
* ssh_key_name, image_id, public_network_id
|
||||
|
||||
OPTIONAL PARAMETERS:
|
||||
|
||||
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
|
||||
db_server_name, db_name, db_username, db_password, db_root_password,
|
||||
app_server_name, web_server_name, admin_username, admin_password,
|
||||
admin_email, dns_nameserver
|
||||
|
||||
**eCommerceAutoScaling.yaml:** If you want a dynamic autoscaling environment,
|
||||
run this yaml file. This yaml files sets up heat autoscaling groups.
|
||||
|
||||
REQUIRED PARAMETERS:
|
||||
|
||||
* ssh_key_name, image_id, public_network_id
|
||||
|
||||
OPTIONAL PARAMETERS:
|
||||
|
||||
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
|
||||
db_server_name, db_name, db_username, db_password, db_root_password,
|
||||
app_server_name, web_server_name, admin_username, admin_password,
|
||||
admin_email, dns_nameserver
|
||||
|
||||
The following 4 yaml files are called by the primary files above, and are by
|
||||
default expected to be in a nested subdirectory:
|
||||
|
||||
**setup_network.yaml:**
|
||||
This file creates 3 separate private networks, one for each tier. In
|
||||
addition it creates two load balancers (using neutron LBaaS V2), one which
|
||||
has a public IP that connects the web private network to the public
|
||||
network, and one with a private IP that connects the web network to the
|
||||
services network. The template also creates a router connecting the
|
||||
services network to the database network. In addition to the networks and
|
||||
routers, the template creates 3 security groups, one for each of the tiers.
|
||||
|
||||
**launch_web_layer.yaml:**
|
||||
This template file launches the web layer nodes. In addition to launching
|
||||
instances, it installs and configures Apache and Apache modproxy which is
|
||||
used to redirect traffic to the application nodes.
|
||||
|
||||
**launch_services_layer.yaml:**
|
||||
This template file launches the services layer nodes. In addition to
|
||||
launching the instances, it installs Apache, PHP, MySQL client, and
|
||||
OpenCart.
|
||||
|
||||
**launch_sql_layer.yaml:**
|
||||
This template file launches the database layer node and installs MySQL.
|
||||
In addition it creates a cinder block device to store the database files.
|
||||
The template also creates the required users and databases for the OpenCart
|
||||
application.
|
||||
|
||||
-------------------------------
|
||||
Running the heat template files
|
||||
-------------------------------
|
||||
|
||||
First you need to source your credential file. You may download a copy of the
|
||||
credential file from Horizon under Project>Compute>Access & Security>API
|
||||
Access
|
||||
|
||||
**Example to setup the static environment**::
|
||||
|
||||
openstack stack create --template eCommerceStatic.yaml --parameter ssh_key_name=mykey --parameter image_id=ubuntu --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network OpenCart
|
||||
|
||||
**Example to setup the autoscaling environment**::
|
||||
|
||||
openstack stack create --template eCommerceAutoScaling.yaml --parameter ssh_key_name=mykey --parameter image_id=centos --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network OpenCart

This is the main Heat template for the eCommerce Workload Architecture created by the
|
||||
Enterprise Working Group. This version of the template does not include autoscaling,
|
||||
and does not require ceilometer.
|
||||
This template calls multiple nested templates which actually do the
|
||||
majority of the work. This file calls the following yaml files in a ./nested subdirectory
|
||||
setup_network.yaml sets up the security groups and networks for Web, App, and Database
|
||||
launch_services_layer.yaml starts up application servers and does on-the-fly builds
|
||||
launch_web_layer.yaml starts up web servers and does on-the-fly builds
|
||||
launch_sql_layer.yaml starts up mysql server and does on-the-fly builds.
|
||||
|
||||
NOTE: This serves as a guide to new users and is not meant for production deployment.
|
||||
|
||||
REQUIRED YAML FILES:
|
||||
setup_network.yaml, launch_services_layer.yaml, launch_sql_layer.yaml, launch_web_layer.yaml
|
||||
|
||||
REQUIRED PARAMETERS:
|
||||
ssh_key_name, image_id, public_network_id

OpenStack Workload Reference Architecture: <workload-name>
|
||||
==========================================================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
This section provides detailed information on what the workload is.
|
||||
|
||||
Please include a high-level overview diagram whenever possible.
|
||||
|
||||
OpenStack for <workload>
|
||||
------------------------
|
||||
|
||||
This section provides detailed information on which OpenStack services
|
||||
are required to support this workload.
|
||||
|
||||
Please include all **core** and **optional** services.
|
||||
|
||||
Please provide a brief description of each services used in this document.
|
||||
For example:
|
||||
|
||||
.. list-table:: **Core services**
|
||||
:widths: 20 50
|
||||
|
||||
* - Compute (Nova)
|
||||
- Manages the life cycle of compute instances, including spawning,
|
||||
scheduling, and decommissioning of virtual machines (VMs) on demand.
|
||||
* - Object Storage (Swift)
|
||||
- Stores and retrieves arbitrary unstructured data objects via a RESTful
|
||||
HTTP-based API. Highly fault-tolerant with data replication and
|
||||
scale-out architecture.
|
||||
|
||||
Please include a logical representation diagram and a functional interaction
|
||||
diagram of the OpenStack services whenever possible.
|
||||
|
||||
Structuring a <workload> with OpenStack
|
||||
---------------------------------------
|
||||
|
||||
This section provides detailed information on the workload requirements and
|
||||
specify how each of the OpenStack services (mentioned in previous section)
|
||||
are used to satisfy the workload requirements.
|
||||
|
||||
Please include a diagram of the deployment architecture whenever possible.
|
||||
|
||||
Demonstration and Sample Code
|
||||
-----------------------------
|
||||
|
||||
Every workload must be accompanied by at least one sample code that can be
|
||||
used to provision such workload environment. This can be either Heat template,
|
||||
Murano packages, or other code (e.g. ansible)
|
||||
|
||||
This section provides a brief summary of the sample code. You do not need to
|
||||
explain every single step in the sample code. However, please provide
|
||||
sufficient information to explain what the sample code is trying to achieve.
|
||||
|
||||
Scope and Assumptions
|
||||
---------------------
|
||||
|
||||
This section describes the specific scope, limitation or assumption made for
|
||||
this workload reference architecture.
|
||||
|
||||
For example: The Heat template provided for this reference architecture
|
||||
assumes that the web application workload is deployed in a single-region,
|
||||
single-zone OpenStack environment. The deployment in a multi-zone/multi-region
