[jira] [Commented] (STRATOS-119) HA and scaling support for the instances using Region and Zone

["Nirmal Fernando (JIRA)" <ji...@apache.org>]

Nirmal Fernando commented on STRATOS-119:
-----------------------------------------

The implementation got changed slightly. Now, autoscaler decides the place the next instance should start and give it wrapped as a Partition. CC knows how to spawn an instance using a Partition.

> In order to support HA policies in autoscaler in the new architecture, it is required to extend the cloud controller to support Region, Zone and other available locations to create a new instance from the jclouds API. 
> So that from the autoscaler, we can specify where should we start the instance. Eg: In openstack we can isolate the compute nodes using Region (geographically separated with specific endpoint), zone (used to partition a set of physical machines within a region) and Host (used to partition a set of common features of instances into one logical group).
