AWS Certified Solutions Architect – Professional (SAP-C02) — Question 125
A delivery company needs to migrate its third-party route planning application to AWS. The third party supplies a supported Docker image from a public registry. The image can run in as many containers as required to generate the route map.
The company has divided the delivery area into sections with supply hubs so that delivery drivers travel the shortest distance possible from the hubs to the customers. To reduce the time necessary to generate route maps, each section uses its own set of Docker containers with a custom configuration that processes orders only in the section's area.
The company needs the ability to allocate resources cost-effectively based on the number of running containers.
Which solution will meet these requirements with the LEAST operational overhead?
Answer options
- A. Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster on Amazon EC2. Use the Amazon EKS CLI to launch the planning application in pods by using the --tags option to assign a custom tag to the pod.
- B. Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster on AWS Fargate. Use the Amazon EKS CLI to launch the planning application. Use the AWS CLI tag-resource API call to assign a custom tag to the pod.
- C. Create an Amazon Elastic Container Service (Amazon ECS) cluster on Amazon EC2. Use the AWS CLI with run-tasks set to true to launch the planning application by using the --tags option to assign a custom tag to the task.
- D. Create an Amazon Elastic Container Service (Amazon ECS) cluster on AWS Fargate. Use the AWS CLI run-task command and set enableECSManagedTags to true to launch the planning application. Use the --tags option to assign a custom tag to the task.
Correct answer: D
Explanation
Option D is correct because it utilizes AWS Fargate, which abstracts away the infrastructure management, resulting in the least operational overhead while still allowing for tagging. The other options involve Amazon EC2, which requires more management and operational oversight, making them less suitable for the company's needs.
