Question

Difficulty: MediumAWS Compute Services

Match each application workload requirement to the most appropriate AWS compute service.

  • A simple web application that needs a low-cost, all-in-one virtual private server (VPS) with pre-configured software stacks.Amazon Lightsail
  • A containerized microservice that must run continuously without the overhead of provisioning, configuring, or scaling physical virtual machine instances.AWS Fargate
  • An event-driven backend service that processes files in response to uploads, running only for a few seconds per execution.AWS Lambda
  • A legacy database application requiring custom operating system kernel modifications and full administrative root access to the virtual machine.Amazon EC2

Answer

The correct matches pair the simple VPS application with Amazon Lightsail, the serverless containerized microservice with AWS Fargate, the event-driven short-lived service with AWS Lambda, and the legacy database requiring root OS access with Amazon EC2.
The matches correctly align each business workload with the most appropriate AWS compute service based on the level of management control, scaling behavior, and application packaging. Amazon Lightsail is best for simple, bundled VPS hosting. AWS Fargate is ideal for serverless container workloads. AWS Lambda is the standard service for short-lived, event-driven functions. Amazon EC2 provides the required root operating system access for custom legacy applications.

Step-by-Step Solution

1
Analyze the operational control and management requirements of each workload.
Identify workloads that require full guest OS administration versus those that can be run in a serverless or packaged environment.
This establishes the basic distinction between Infrastructure as a Service (IaaS) like EC2 and serverless or managed services like Fargate and Lambda.
2
Differentiate between containerized, event-driven, and standard VPS requirements.
Classify the microservice as container-based, the file-processing script as event-driven/short-lived, and the simple web app as a standard VPS.
This matches workloads to specialized compute offerings designed to optimize cost and management overhead for those specific paradigms.
3
Map each categorized workload to its corresponding AWS compute service.
VPS workload maps to Lightsail; containers without host management maps to Fargate; event-driven functions map to Lambda; root-access OS virtualization maps to EC2.
Completes the matching alignment in accordance with official AWS architectural best practices.
