Question

A company has an application that stores data in Amazon RDS instances. The application periodically experiences surges of high traffic that cause performance problems. During periods of peak traffic, a developer notices a reduction in query speed in all database queries. The team’s technical lead determines that a multi-threaded and scalable caching solution should be used to offload the heavy read traffic. The solution needs to improve performance. Which solution will meet these requirements with the LEAST complexity?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Use Amazon ElastiCache for Memcached to offload read requests from the main database. Amazon ElastiCache provides in-memory caching (Redis/Memcached) to reduce latency and offload the database.
