Object Storage

Eucalyptus supports Walrus and Riak CS as its object storage backend. There is no extra planning if you use Walrus. If you use Riak CS, you can use a single Riak CS cluster for several Eucalyptus clouds. Basho (the vendor of RiakCS) recommends five nodes for each Riak CS cluster. This also means that you have to set up and configure a load balancer between the Riak CS nodes and the object storage gateway (OSG).
