Question

A company has a social media application that receives large amounts of traffic. User posts and interactions are continuously updated in an Amazon RDS database. The data changes frequently, and the data types can be complex. The application must serve read requests with minimal latency. The application's current architecture struggles to deliver these rapid data updates efficiently. The company needs a solution to improve the application's performance. Which solution will meet these requirements?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Create an Amazon ElastiCache for Redis cluster. Update the application code to use a write-through caching strategy and read the data from Redis. Amazon ElastiCache provides in-memory caching (Redis/Memcached) to reduce latency and offload the database.
