Preparing a cluster
Following, you can find instructions on creating a cluster using the ElastiCache console, the AWS CLI, or the ElastiCache API.
You can also create an ElastiCache cluster using AWS CloudFormation. For more information, see AWS::ElastiCache::CacheCluster in the AWS Cloud Formation User Guide, which includes guidance on how to implement that approach.
Whenever you create a cluster or replication group, it is a good idea to do some preparatory work so you won't need to upgrade or make changes right away.
