Problem Statement

Currently CloudStack does not offer a flexible pluggable framework for users to easily integrate and configure any 3rd-party object stores for such backup services as registering templates, taking snapshots, etc. Along with Edison's recent refactored storage subsystem 2.0, we are proposing to develop a storage backup data object store plugin framework to support to allow CloudStack to systematically manage and configure various types of backup data stores from different vendors and different configuration combinations. .

Storage DataStore Plugin Framework

In this new refactored backup datastore plugin framework, we have clearly defined those pluggable service interfaces, such as PrimaryDataStore, ImageDataStore, DataMotionStrategy, AutoScaleStrategy, etc, so that different storage providers can develop their vendor-specific plugins based on the well-defined contracts that can be seemlessly managed by CloudStack orchestration.

Benefits of Backup DataStore Plugin Framework

With this new plugin framework, we should be able to achieve following functionalities:

Enable region wide object backup

...

instead of currently copying templates from one zone to another.

Make SSVM optional and configurable

...

Support different

...

object store provides in a uniform and extensible fashion.

S3, Swift, NFS, etc.

Support

Backup Datastore Plugin Framework

pluggable Data Motion Strategies to handle various protocol combinations.

Provide CloudStack framework support to launch NFS transfer VMs dynamically for data transfer.

...

Support pluggable Auto Scale strategies to load balance data streams.
