Difficulty: MediumAWS Compute Services

An organization is evaluating different AWS compute offerings for its upcoming migration. Match each workload requirement to the most appropriate AWS compute service.

  • A short-lived microservice that processes media uploads under 45 seconds and must scale to zero when inactive.AWS Lambda
  • A legacy accounting application requiring custom kernel modifications and direct root access to the underlying operating system.Amazon EC2
  • A containerized e-commerce API that needs serverless deployment without any virtual machine management overhead.AWS Fargate
  • A simple promotional WordPress website needing low, predictable monthly pricing bundled with data transfer.Amazon Lightsail

Answer

The correct matches pair: 1) the event-driven scaling-to-zero workload with AWS Lambda; 2) the legacy system requiring kernel-level OS configurations with Amazon EC2; 3) the serverless containerized workload with AWS Fargate; and 4) the simple website with predictable pricing with Amazon Lightsail.
The correct matches map each distinct application requirement to the AWS compute service that meets its management, pricing, and infrastructure needs: AWS Lambda for event-driven serverless functions; Amazon EC2 for workloads needing full operating system customization; AWS Fargate for serverless container workloads; and Amazon Lightsail for simple, low-cost virtual private servers.

Step-by-Step Solution

1
Analyze each workload on the left to identify their primary constraints.
Identified specific characteristics: event-driven serverless scaling (left_1), kernel/root OS access (left_2), serverless containers (left_3), and predictable, simple cost VPS (left_4).
Understanding key workload characteristics is necessary to match them with specialized AWS compute categories.
2
Evaluate the capabilities of the compute services on the right.
Mapped AWS Lambda (event-driven functions), Amazon EC2 (fully customizable virtual machines), AWS Fargate (serverless container orchestration), and Amazon Lightsail (predictable VPS packages).
This defines the target features of each compute offering to determine the ideal pairings.
3
Perform the matching based on architectural best practices.
Matched left_1 with AWS Lambda, left_2 with Amazon EC2, left_3 with AWS Fargate, and left_4 with Amazon Lightsail.
This aligns the workloads with their corresponding optimal AWS compute service.
