# Valet
Valet gives OpenStack the ability to optimize cloud resources while simultaneously meeting a cloud application's QoS requirements. Valet provides an api service, a placement optimizer (Ostro), a high availability data storage and persistence layer (Music), and a set of OpenStack plugins.
**IMPORTANT**: [Overall AT&T AIC Installation of Valet is covered in a separate document](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/allegro/atRef/refs/heads/master/renderFile/doc/aic/README.md).
Learn more about Valet:
* [OpenStack Newton Summit Presentation](https://www.openstack.org/videos/video/valet-holistic-data-center-optimization-for-openstack) (Austin, TX, 27 April 2016)
* [Presentation Slides](http://www.research.att.com/export/sites/att_labs/techdocs/TD_101806.pdf) (PDF)
Valet consists of the following components:
* [valet-openstack](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/allegro/atRef/refs/heads/master/renderFile/valet_os/README.md): a set of OpenStack plugins used to interact with Valet
* [valet-api](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/allegro/atRef/refs/heads/master/renderFile/valet_api/README.md): an API engine used to interact with Valet
* [Ostro](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/ostro/atRef/refs/heads/master/renderFile/README): a placement optimization engine
* [Music](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/music/atRef/refs/heads/master/renderFile/README.md): a data storage and persistence service
* [ostro-listener](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/allegro/atRef/refs/heads/master/renderFile/ostro_listener/README.md): a message bus listener used in conjunction with Ostro and Music
* [havalet](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/allegro/atRef/refs/heads/master/renderFile/havalet/README.md): a service that assists in providing high availability for Valet

* [Placement API](https://codecloud.web.att.com/plugins/servlet/readmeparser/display/ST_CLOUDQOS/allegro/atRef/refs/heads/master/renderFile/valet_api/doc/README.md): API requests/responses

@ -12,8 +12,15 @@ Valet1.0/Ostro features
- Resource standby
When allocating resources (CPU, memory, disk, and later network bandwidth), Ostro intentionally leaves a certain percentage of resources as unused. This is because of the concern of load spikes of tenant applications. Later, we will deploy more dynamic mechanism in the future version of Ostro.
- High availability
Ostro replicas run as active-passive way. When active Ostro fails, automatically the passive one is activated via HAValet. All data is updated in MUSIC database at runtime whenever it is changed. When the passive Ostro is activated, it gets data from MUSIC to initialize its status rather than from OpenStack. Ostro also takes ping messages to show if it is alive or not.
- Runtime update via the Oslo message bus or RO
Working on this.
- Migration tip

# Valet
Valet gives OpenStack the ability to optimize cloud resources while simultaneously meeting a cloud application's QoS requirements. Valet provides an api service, a placement optimizer (Ostro), a high availability data storage and persistence layer (Music), and a set of OpenStack plugins.
**IMPORTANT**: [Overall Installation of Valet is covered in a separate document](https://github.com/att-comdev/valet/blob/master/doc/valet_os.md).
Learn more about Valet:
* [OpenStack Newton Summit Presentation](https://www.openstack.org/videos/video/valet-holistic-data-center-optimization-for-openstack) (Austin, TX, 27 April 2016)
* [Presentation Slides](http://www.research.att.com/export/sites/att_labs/techdocs/TD_101806.pdf) (PDF)
Valet consists of the following components:
* [valet-openstack](https://github.com/att-comdev/valet/blob/master/doc/valet_os.md): a set of OpenStack plugins used to interact with Valet
* [valet-api](https://github.com/att-comdev/valet/blob/master/doc/valet_api.md): an API engine used to interact with Valet
* [Ostro](https://github.com/att-comdev/valet/blob/master/doc/ostro.md): a placement optimization engine
* [Music](https://github.com/att/music): a data storage and persistence service
* [ostro-listener](https://github.com/att-comdev/valet/blob/master/doc/ostro_listener.md): a message bus listener used in conjunction with Ostro and Music
