Hi, Flocker provides a neat abstraction to the underlying choice of storage. It has a range of different backends - EBS, OpenStack Cinder, ZFS (experimental), EMC scale.io, EMC Xtrem.io and many more.<p>This means that if you decide to move your application to a different underlying platform - your storage specific application and infrastructure code remains the same and all that changes is a Flocker configuration.<p>We have seen this benefit with a number of folks who need to support multiple infrastructures.  Before Flocker - there were multiple code-paths depending on the underlying storage.  Using Flocker - the same code-path was used.
