Difficulty: EasyAWS Compute Services

A company is selecting compute services for various workloads. Match each business workload requirement with the AWS compute service that is most appropriate.

  • Amazon EC2Hosting a legacy application that requires full administrative (root) access to the underlying guest operating system.
  • AWS LambdaRunning code in response to events, such as processing a new file uploaded to an Amazon S3 bucket, without managing any infrastructure.
  • Amazon LightsailDeploying a simple, pre-configured WordPress blog with predictable, low-cost monthly pricing.
  • AWS FargateRunning containerized applications without needing to provision, patch, or manage the underlying virtual servers.

Answer

The correct matches pair Amazon EC2 with legacy applications requiring OS administrative access, AWS Lambda with short event-driven code execution, Amazon Lightsail with simple websites under predictable pricing, and AWS Fargate with serverless container deployment.
Each compute service on AWS is optimized for specific levels of control, scale, and simplicity. Amazon EC2 matches full administrative OS access; AWS Lambda matches short-lived, event-driven functions; Amazon Lightsail matches pre-configured software with predictable monthly pricing; and AWS Fargate matches containerized applications run without provisioning underlying EC2 instances.

Step-by-Step Solution

1
Evaluate the infrastructure management requirements of each workload (e.g., control over the OS, serverless execution, containerization, or simple pre-configured setups).
Identify that full root/OS access requires Amazon EC2, serverless execution of short-lived code requires AWS Lambda, simple pre-configured websites map to Amazon Lightsail, and serverless containers require AWS Fargate.
This establishes the fundamental alignment between the AWS compute service types and the business constraints.
2
Verify each service alignment against the AWS Shared Responsibility Model and operational model to ensure accuracy.
Confirm that Amazon EC2 provides maximum control, AWS Lambda is event-driven serverless, Amazon Lightsail is simplified VPS, and AWS Fargate is container-focused serverless.
Ensures no incorrect pairings are made based on minor service overlaps.
