Compute
RecognitionAmazon EC2
Resizable virtual compute instances in AWS, relevant here as an application runtime and role-backed workload surface.
Key points
- Instance roles provide temporary AWS credentials to application code.
- Application artifacts and configuration can target EC2 without requiring candidates to administer operating systems.
- Instance health and load-balancer health do not replace application observability.
Best-known use cases
- Host applications requiring virtual-machine control.
- Run role-authenticated application workloads in existing compute environments.
What candidates often confuse it with
- EC2 exposes virtual instances; Lambda runs event-invoked functions without server administration.
- Elastic Beanstalk manages an application environment over AWS resources; EC2 is the underlying compute primitive.
Key takeaway
Recognize EC2 as a workload runtime, while keeping server and operating-system administration outside DVA-C02.
