Summary
In this chapter, we have learned about Amazon ElastiCache and how you can use it to help with performance problems on a database, minimize geographic latency, and help speed up query times for end users. We've learned that ElastiCache is a fully managed service and offers two types of caching databases, Redis and Memcached, which have different features and are used for different scenarios.
It's very important to know the differences between the two different engines and also between cluster mode enabled and cluster mode disabled for Redis, as the exam will ask questions about which version you can use for a given scenario.
In the next chapter, we will learn how to migrate a database to AWS and the tools that are available to help you – that is, AWS Schema Conversion Tool (SCT) and AWS Database Migration Service (DMS).
