Which solution will meet these requirements MOST cost-effectively?
Modify the RDS for MySQL DB instance to a larger instance size.
Modify the RDS for MySQL DB instance to Amazon DynamoDB.
Configure RDS Proxy. Modify the application configuration file to use the RDS Proxy endpoint.
Modify the RDS for MySQL DB instance to a memory optimized DB instance.
Explanations:
Increasing the instance size could help with more connections, but it would be a costly solution and would require a restart, which may not resolve the root issue of connection management.
Switching to Amazon DynamoDB is a drastic change that would require significant code modifications. It does not directly address the issue of “too many connections” in MySQL.
Configuring RDS Proxy helps manage database connections efficiently by pooling and reusing connections, reducing the strain on the MySQL instance. It requires minimal code changes and is cost-effective.
Memory optimized DB instances (e.g., db.m6g.2xlarge) are more suitable for memory-intensive workloads but do not directly address the connection management issue, and would increase costs significantly.
As I recall, the answer is:
Configure RDS Proxy. Modify the application configuration file to use the RDS Proxy endpoint.
