Question

A company is updating an application to move the backend of the application from Amazon EC2 instances to a serverless model. The application uses an Amazon RDS for MySQL DB instance and runs in a single VPC on AWS. The application and the DB instance are deployed in a private subnet in the VPC. The company needs to connect AWS Lambda functions to the DB instance. Which solution will meet these requirements?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Create Lambda functions inside the VPC with the AWSLambdaVPCAccessExecutionRole policy attached to the Lambda execution role. Modify the RDS security group to allow inbound access from the Lambda security group. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon RDS is a managed relational database that handles patching, backups and failover.
