Deployment Guidelines: Multi Data Center Deployments

Larger deployment topologies are also possible. Cassandra clusters can scale to hundreds of nodes. Each Cassandra node can also be configured with a specific rack and data center assignment. A rack is usually network-near to other racks in the same data center but independently powered. Data centers are geographically dispersed. With rack and data center awareness, Cassandra can use a replication policy that ensures maximum availability should a node, rack, or entire data center fail. An example of a multi-rack/multi-data center deployment is shown below:

Advanced configurations such as these are beyond the scope of this document, but information about Cassandra configuration is publicly available.
