Subject [jira] [Updated] (CLOUDSTACK-747) nTier Apps 2.0 : Internal Load Balancing between the tiers
Date Mon, 29 Apr 2013 16:26:15 GMT

     [ https://issues.apache.org/jira/browse/CLOUDSTACK-747?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alena Prokharchyk updated CLOUDSTACK-747:
-----------------------------------------

    Summary:  nTier Apps 2.0 : Internal Load Balancing between the tiers  (was:  nTier Apps
2.0 : Load Balancing on all Tiers)

Changed the issue subject to "Internal Load Balancing between the tiers" as this is what needs
to be implemented to support LB on all the tiers. The example of deployment would be:

1) Create VPC with 2 tiers: Web and App
2) Provide public LB on Web tier
3) Create internal LB on the App tier, so the instances from the Web tier can access.

> This item is sub task (2.2) of https://issues.apache.org/jira/browse/CLOUDSTACK-621 
> Currently, Load Balancing VPC VR is only supported on one of the Tiers of an nTier Application.
With this release, CloudStack should support load balancing on all tiers of an nTier application.
> Use Case: Users would like to deploy a multi-tier application with the VR load balancing
each of the tiers. As a result, users would be able to provide flexibility and elasticity
at each tier of their application
