There are 4 layers of HA to consider in a cloud deployment: the application itself, the virtual machine the application runs on, and the control plane of the cloud that allows provisioning and managing resources. The OpenStack development community is largely focused on HA of OpenStack itself (i.e. the control plane). VM-level HA has some limited support in OpenStack, but it is not complete. And, while application level HA is largely considered out of scope of OpenStack, Savanna, Heat, and Trove are beginning to touch on this.
This session will focus on the current status of HA at each level, technical challenges that remain, and the research and development activities to close them.
