Which AWS service should the company use to meet these requirements?

Explanations:

Amazon DynamoDB is a fully managed NoSQL database service. It abstracts away the underlying infrastructure, which means the company would not have control over patch management for guest operating systems.

Amazon EC2 (Elastic Compute Cloud) allows users to launch and manage virtual servers (instances) in the cloud. This provides full control over the operating system, including the ability to manage patches.

AWS Lambda is a serverless computing service that runs code in response to events. It does not provide control over an operating system, as it abstracts infrastructure management entirely.

Amazon RDS (Relational Database Service) is a managed database service. While it provides some control over database settings, it does not allow for patch management of the underlying guest operating systems.
