## Introduction
**Use Case and Architecture** is a sub group under CFN WG.  It can give you an technical overview of CFN WG. 

The goal of Use Case and Architecture sub group is to explore CFN related use cases, derive functional requirements based on use cases, give software recommendations to provide functions required by derived fucntional requriements, and maintain a system architecture and software landscape of CFN. Besides, this sub group is also a incubator of CFN subgroups and new feature. It will potentially provide code-level or mathematical or architecture-level implementations of features, software, systems and any for proper use cases before those deliveries be included in any other sub groups.

## Release Planning & Release Notes
For the release of year 2023, Use Case & Architecture sub group will mainly deliver the following task items:

1. Sub-group introduction
    * Link to this task: [https://storyboard.openstack.org/#!/story/2010457](https://storyboard.openstack.org/#!/story/2010457)
2. Use case and architecture document version 1
    * Link to this task:  [https://storyboard.openstack.org/#!/story/2010434](https://storyboard.openstack.org/#!/story/2010434)
    * Description: This doc will interpret the concept of CFN from user perspective, sort out the progress of CFN, analyze use cases and put forward suggestions on how to further promote maturity of CFN
3. Reference algorithm implementation of AI O&M use case
    * Link to this task: [https://storyboard.openstack.org/#!/story/2010869](https://storyboard.openstack.org/#!/story/2010869)
    * Description: In CFN, computing tasks, network and computing resources are having tight collaboration. This implementation targets on creating models of task amount, network traffics and computing resource workloads, and using this models to predict the future status of the task, network and computing resources. With this prediction, CFN can adjust its network bandwidth, computing resource scaling in/out to better serve the task. 


For the release of year 2023, Use Case & Architecture sub group will follow the unified timeline of CFN WG listed at [https://opendev.org/cfn/cfn-overview/src/branch/master/releases/2023-cfn-release-timeline.md](https://opendev.org/cfn/cfn-overview/src/branch/master/releases/2023-cfn-release-timeline.md)
