Akila resolved STRATOS-849.
---------------------------
Resolution: Fixed
> Stratos does not create specified min instance count in deployment policy
> -------------------------------------------------------------------------
>
> Key: STRATOS-849
> URL: https://issues.apache.org/jira/browse/STRATOS-849
> Project: Stratos
> Issue Type: Bug
> Components: Autoscaler
> Reporter: Akila
> Priority: Blocker
> Fix For: 4.1.0 M1
>
>
> Use the following deployment policy with min count - 3
> {
> "id": "deployp",
> "partitionGroup": {
> "id": "ec2",
> "partitionAlgo": "one-after-another",
> "partition": [
> {
> "id": "P1",
> "partitionMax": "10",
> "partitionMin": "3"
> }
> ]
> }

> Stratos will only create 1 LB and 1 service instance. When RuleLog DEBUG logs
> are enabled following can be observed.

> It seems service instance is also created by VMLbClusterMonitor. This is
> wrong. This should be fixed in ClustorMonitorFactory class.
