A company has a web application that uses Amazon API Gateway to route HTTPS requests to AWS Lambda functions. The application uses an Amazon Aurora MySQL database for its data storage. The application has experienced unpredictable surges in traffic that overwhelm the database with too many connection requests. The company needs to implement a scalable solution that is more resilient to database failures as quickly as possible. Which solution will meet these requirements MOST cost-effectively?
