AWS ElastiCache Practical

Introduction

The AWS SOA-CO2 exam includes all features of the ElastiCache service. In this practical, we’ll create an ElastiCache Redis cluster with cluster mode turned off and two Read Replicas. We can connect to this cluster using the cluster endpoint and Redis CLI to store and retrieve key value pairs.

Practical

In the widget below, we’ll take the following steps to create the ElastiCache Redis cluster:

• Create a security group and open port 6379 (default Redis port) to the internet.
• Fetch the public subnet IDs in the default VPC of the region.
• Create an ElastiCache cluster with one node. Review the parameters and configuration for the cluster.
• Create a manual snapshot of the cluster.
• Create a replication group to enable Multi-AZ, automatic failover, and Read Replicas. A replication group is a group of cache clusters that allows us to configure Read Replicas and Multi-AZ configurations. This cluster allows connection over the internet, as defined in the security group ingress rules. Therefore, we can use the Redis CLI from any computer to access it.

Note: This practical will take a lot of time to create resources.
