Question

Difficulty: MediumAWS Compute Services

A digital marketing agency needs to deploy two new workloads on AWS:
1. A simple promotional website that requires a pre-configured web server, database, and domain management, all under a predictable monthly pricing plan.
2. A short-lived, event-driven microservice that runs code in response to user contact form submissions, executing for less than five seconds.

Which TWO AWS compute services should the agency select to host these workloads? (Select TWO.)

  1. Amazon LightsailAnswer
  2. AWS LambdaAnswer
  3. C
    Amazon EC2
  4. D
    AWS Fargate
  5. E
    AWS Elastic Beanstalk

Answer

Amazon Lightsail and AWS Lambda
Amazon Lightsail is the best choice for the first workload because it provides pre-configured templates for popular web applications and databases with a simple, predictable monthly pricing plan. AWS Lambda is the ideal fit for the second workload because it is a serverless service that executes code on demand for short-lived events, scaling automatically without needing server management.

Step-by-Step Solution

1
Analyze the requirements of the first workload: a basic website requiring a pre-configured stack (web server, database) and a predictable, simple monthly cost.
Amazon Lightsail is designed specifically for this use case, providing a simplified console, bundled resources, and predictable pricing.
Choosing Amazon Lightsail satisfies the first requirement efficiently without administrative overhead or variable billing concerns.
2
Analyze the requirements of the second workload: an event-driven, short-lived task running for less than 5 seconds in response to uploads.
AWS Lambda is a serverless compute service that runs code only when triggered by events and charges only for execution time.
Choosing AWS Lambda avoids provisioning a continuous server for sporadic, short-lived tasks, minimizing costs.

Key Concept

Selecting appropriate AWS compute services based on workload characteristics such as administrative effort, event-driven nature, and cost predictability.
