CreateClusterRequest
Create as many Clusters as you want, but create at least one. Each Cluster groups together Nodes that you want to treat as a collection. Within the Cluster, you will set up some Nodes as active Nodes, and some as backup Nodes, for Node failover purposes. Each Node can belong to only one Cluster.

Specify a type. All the Nodes that you later add to this Cluster must be this type of hardware. One Cluster instance can't contain different hardware types. You won't be able to change this parameter after you create the Cluster.
The ARN of the IAM role for the Node in this Cluster. The role must include all the operations that you expect these Node to perform. If necessary, create a role in IAM, then attach it here.
