Understanding the importance of in-memory caching options with Amazon Elasticache
Often, you will find yourself accessing a set of data regularly, which is what we term as frequently accessed data. Every time you run a query on the database, you consume resources to perform the query operation and then retrieve that data. Overall, this can add additional load to your database and may even affect performance as you constantly write new data to the database.
As part of your overall application architecture, you should consider using in-memory caching engines offered by AWS to alleviate the load on your primary databases. Amazon Elasticache is a web service that offers in-memory caching in the cloud. By caching frequently accessed data on Amazon Elasticache, applications can be configured to retrieve frequently accessed data from it rather than make more expensive database calls.
AWS offers two in-memory caching engines, as follows:
