AWS Certified Developer Associate DVA-C02 Practice Question
A developer has built a web application that interfaces with a product catalog stored in Amazon DynamoDB. The application experiences intermittent periods of high read traffic which could potentially throttle DynamoDB read capacity. To maintain application responsiveness, which service should the developer integrate to provide an effective caching layer?
Amazon ElastiCache is the appropriate service to be used for adding a caching layer because it supports caching strategies like write-through, read-through, and lazy loading which can handle high traffic and prevent throttling issues with DynamoDB. It supports both Memcached and Redis in-memory data stores which are suitable for various caching use cases.
