AWS Certified Developer Associate DVA-C02 Practice Question
An e-commerce site hosted on AWS uses Amazon RDS MySQL to store product catalog data. During seasonal sales events, the application experiences high read latency because the same catalog queries are executed thousands of times per second. The development team wants a fully managed service that can keep transient, in-memory copies of this frequently requested data to reduce latency and offload reads from RDS. Which service should they implement?
Amazon ElastiCache for Redis provides a managed, in-memory data store that can cache the results of frequent product catalog queries, delivering sub-millisecond response times and reducing the read load on Amazon RDS.
Amazon RDS read replicas reduce read pressure but still rely on disk-based storage and introduce replication lag. Amazon CloudFront caches HTTP objects at edge locations; it cannot cache database query results served from an RDS instance within a VPC. Amazon DynamoDB Accelerator (DAX) is a caching layer only for DynamoDB tables, not for MySQL databases. Therefore, ElastiCache is the best fit for this scenario.
