Answer: Amazon ElastiCache, which improves database performance by caching frequently accessed data in-memory.
The correct answer is C, Amazon ElastiCache. It is an in-memory data caching service that can significantly improve the performance of I/O intensive applications, including databases like Amazon RDS. By caching frequently accessed data in-memory, ElastiCache reduces the database load and the number of read operations sent to the database, thus enhancing overall performance. Option A, Amazon DynamoDB Accelerator (DAX), is designed for Amazon DynamoDB and not for Amazon RDS. Option B, Amazon EMR, is used for big data processing and is not specifically aimed at improving RDS performance. Option D, Amazon Redshift, is a data warehousing service and does not directly address the performance improvement of an Amazon RDS database.
