Answers
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.
Suggested answer: D

Explanation:

Amazon ElastiCache for Redis:An in-memory data store known for extremely low latency, ideal for caching frequently accessed, complex data.

Write-Through Caching:Ensures that data is always consistent between the cache and the database. Writes go to both Redis and RDS.

Performance Gains:Redis handles reads with minimal latency, offloading the RDS database and improving the application's responsiveness.
