Explanation
Amazon EC2 (Elastic Compute Cloud) is an Infrastructure as a Service (IaaS) offering where customers have full control over the operating system and are responsible for:
- Applying operating system patches
- Security updates
- Application patches
- Operating system configuration
Why the other options are incorrect:
- Amazon DynamoDB: A fully managed NoSQL database service where AWS handles all patching, maintenance, and scaling
- AWS Lambda: A serverless compute service where AWS manages the underlying infrastructure, including operating system patches
- AWS Fargate: A serverless compute engine for containers where AWS manages the underlying infrastructure and operating system
In the Shared Responsibility Model, Amazon EC2 falls under the customer's responsibility for operating system management, while the other services are fully managed by AWS.
