Valet

Valet is a cloud resource placement optimization service. Valet gives OpenStack the ability to optimize cloud resources while simultaneously meeting a cloud application's QoS requirements. Through model driven orchestration, the target state of Valet is to provide “holistic OpenStack data-plane resource placement”. Valet provides an api service, a placement optimizer (Ostro), a high availability data storage and persistence layer (Music), and a set of OpenStack plugins.

Why Valet exists:

For large-scale, multi-tenant cloud operators, there is a large demand for tenant specific service requests. This demand drives the growth of the number of cloud availability zones and compartmentalization of the cloud, which then leads to increased provisioning and sub-optimal use of cloud and staff resources. Also, security requirements lead us to place specialized network appliances of these tenants separately into “exclusive” hosts that do not have internet connectivity.

Valet responds to the challenges outlined above by enhancing OpenStack Nova scheduling to develop resource management optimization. By planning the placement of all the cloud resources for an application in a holistic manner, there is opportunity to reduce cross-rack traffic, reduce resource fragmentation, and save on operating costs.

Learn more about Valet:

Valet consists of the following components:

  • valet-openstack: a set of OpenStack plugins used to interact with Valet
  • valet-api: an API engine used to interact with Valet
  • Ostro: a placement optimization engine
  • ostro-listener: a message bus listener used in conjunction with Ostro and Music
