This session will include the following subject(s):

Placement groups in Nova:

EC2 recently introduced Placement Group APIs to ensure proximity of HPC instances within a group (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using_cluster_computing.html).
The proposal is to introduce similar APIs in Nova, potentially supporting also additional placement policies/strategies, such as anti-affinity for availability purposes. As a next step, the goal is to refine the notion of proximity/anti-affinity to be able to reflect different levels of "proximity"/"isolation"/etc (e.g., "different racks"). As a result, it will be possible to reflect membership of instances in groups in a more efficient way (compared to using metadata today), and to drive placement decisions by the scheduler in a more flexible and intelligent way.

VM Ensembles (Group Scheduling) - API:

The session will propose and discuss the notion of group scheduling. An API will be proposed to enable the user to perform the scheduling of a group. The group scheduling will enable the tenant to benefit from filters that provide anti affinity and network proximity to provide elevated service levels in terms of (high) availability and performance to applications that run in the cloud.
