Amazon ElastiCache is a fully-managed, in-memory caching offering from Amazon Web Services. It's primarily used to improve application and database performance and can also be used for storing ephemeral data such as sessions and analytics.

Learning how to implement different caching strategies using Amazon ElastiCache will make you more effective at building high-performance solutions on AWS.

In this lab, you will create a simple data access layer that stores data in an Amazon S3 bucket. You will then extend the data layer to cache the Amazon S3 in Amazon ElastiCache in order to improve performance.

Please note: this lab creates an Amazon ElastiCache cluster which can take up to fifteen minutes to complete. Please make sure you have enough time available before starting the lab.
