Before you install Eucalyptus, we recommend that you think about the
features you plan to implement with Eucalyptus. These features are detailed
in the following sections.
Windows Guest OS Support
This topic details what Eucalyptus needs in order to use Windows as a guest operating system.
SAN Support Eucalyptus includes optional, subscription only support for integrating enterprise-grade SAN (Storage Area Network) hardware devices into a Eucalyptus cloud.
Availability Zone Support Eucalyptus offers the ability to create multiple local availability zones.
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).
