*user* from RequestContext.

senlin

Senlin is a clustering service for OpenStack cloud. It creates and operates clusters of homogenous objects exposed by other OpenStack services. The goal is to make orchestration of collections of similar objects easier.

Senlin provides ReSTful APIs to users so that they can associate various policies to a cluster. Sample policies include placement policy, load balancing policy, failover policy, scaling policy, ... and so on.

Developers will decide when to contribute it to OpenStack community.
