A company needs to troubleshoot its Amazon Aurora Serverless MySQL database. The company selected a db.t3, medium instance class for the database’s initial deployment. The database experienced light usage, and performance was normal. As the number of client connections increases, the application that is connected to the database is experiencing higher latency and occasional lost connections.
