Deploying Deployment topics. Production deployment planning Production deployment planning requires knowledge of the initial volume of data to store and an estimate of the typical application workload. Configuring replication Choose a data partitioner and replica placement strategy. Single data center deployment A deployment scenario with a mixed workload cluster has only one data center for each type of workload. Multiple data center deployment A deployment scenario with a mixed workload cluster has more than one data center for each type of node. Single-token architecture deployment Use single-token architecture deployment when you are not using virtual nodes (vnodes). Calculating tokens Tokens assign a range of data to a particular node within a data center. Expanding a DataStax AMI cluster To expand your EC2 implementations, use OpsCenter to provision a new cluster, add a new cluster, or add nodes to a cluster.
