AWS ElastiCache - Interfaces

The ElastiCache set up in the previous chapter can aslo be done by one of the following methods. Below are the interfaces through we can interact with AWS ElastiCache.

AWS Management Console

The AWS Management Console is the easiest way to manage Amazon ElastiCache. The console lets you create cache clusters, add and remove cache nodes, and perform other administrative tasks without having to write any code. The console also provides cache node performance graphs from CloudWatch, showing cache engine activity, memory and CPU utipzation, as well as other metrics.

The below diagram shows the ElastiCache dashboard after we login to the AWS console and navigate to ElastiCache service.

AWS CLI

You can also use the AWS Command Line Interface (AWS CLI) for ElastiCache. The AWS CLI makes it easy to perform one-at-a-time operations, such as starting or stopping your cache cluster. You can also invoke AWS CLI for ElastiCache commands from a scripting language of your choice, letting you automate repeating tasks.

The below diagram shows the result of AWS CLI command to describe the subnet groups we have for the ElastiCache clusters created.

AWS SDK

If you want to access ElastiCache from an apppcation, you can use one of the AWS software development kits (SDKs). The SDKs wrap the ElastiCache API calls and insulate your apppcation from the low-level details of the ElastiCache API. You provide your credentials, and the SDK pbraries take care of authentication and request signing.
