Creating a Redis Replication Group from Scratch

This topic covers how to create a Redis replication group without using an existing Redis cluster as the primary. You can create a Redis (cluster mode disabled) or Redis (cluster mode enabled) replication group from scratch using the ElastiCache console, the AWS CLI, or the ElastiCache API.

Before you continue, decide whether you want to create a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group. For guidance in deciding, see Replication: Redis (cluster mode disabled) vs. Redis (cluster mode enabled).
