A gaming company has a web application that displays scores. The application runs on Amazon EC2 instances behind an Application Load Balancer. The application stores data in an Amazon RDS for MySQL database. Users are starting to experience long delays and interruptions that are caused by database read performance. The company wants to improve the user experience while minimizing changes to the application's architecture.
What should a solutions architect do to meet these requirements?

2. B. Use RDS Proxy between the application and the database.
3. C. Migrate the application from EC2 instances to AWS Lambda.
4. D. Migrate the database from Amazon RDS for MySQL to Amazon DynamoDB.

Correct Answer: A
ElastiCache can help speed up the read performance of the database by caching frequently accessed data, reducing latency and allowing the application to access the data more quickly. This solution requires minimal modifications to the current architecture, as ElastiCache can be used in conjunction with the existing Amazon RDS for MySQL database.
