> GraceFul shutdown for the instances
> -----------------------------------
>
> Key: STRATOS-330
> URL: https://issues.apache.org/jira/browse/STRATOS-330
> Project: Stratos
> Issue Type: Improvement
> Components: Autoscaler, Cartridge Agent, Cloud Controller, Stratos
> Manager
> Affects Versions: 4.0.0 M5
> Reporter: reka thirunavukkarasu
> Assignee: reka thirunavukkarasu
> Fix For: 4.0.0 Alpha
>
>
> When an instance gets terminated via autoscaler in the case of scale down or
> unsubscribe, it is required to clean up the data in the instance before
> performing the actual termination of the instance. In order to achieve this
> with stratos:
> * Autoscaler will call the SM to notify the termination to the instances
> * SM will send the notification to the specific instance via
> instance.notifier topic.
> * Instance will receive the event and perform the cleanup task and then send
> another event as ReadyToTerminate to instance.status topic
> * CC will receive the event and terminate the instance.
