Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 511 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 511
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company hosts a data-processing application on Amazon EC2 instances. The application polls an Amazon Elastic File System (Amazon EFS) file system for newly uploaded files. When a new file is detected, the application extracts data from the file and runs logic to select a Docker container image to process the file. The application starts the appropriate container image and passes the file location as a parameter.

The data processing that the container performs can take up to 2 hours. When the processing is complete, the code that runs inside the container writes the file back to Amazon EFS and exits.

The company needs to refactor the application to eliminate the EC2 instances that are running the containers.

Which solution will meet these requirements?

  • A. Create an Amazon Elastic Container Service (Amazon ECS) cluster. Configure the processing to run as AWS Fargate tasks. Extract the container selection logic to run as an Amazon EventBridge rule that starts the appropriate Fargate task. Configure the EventBridge rule to run when files are added to the EFS file system.
  • B. Create an Amazon Elastic Container Service (Amazon ECS) cluster. Configure the processing to run as AWS Fargate tasks. Update and containerize the container selection logic to run as a Fargate service that starts the appropriate Fargate task. Configure an EFS event notification to invoke the Fargate service when files are added to the EFS file system.
  • C. Create an Amazon Elastic Container Service (Amazon ECS) cluster. Configure the processing to run as AWS Fargate tasks. Extract the container selection logic to run as an AWS Lambda function that starts the appropriate Fargate task. Migrate the storage of file uploads to an Amazon S3 bucket. Update the processing code to use Amazon S3. Configure an S3 event notification to invoke the Lambda function when objects are created.
  • D. Create AWS Lambda container images for the processing. Configure Lambda functions to use the container images. Extract the container selection logic to run as a decision Lambda function that invokes the appropriate Lambda processing function. Migrate the storage of file uploads to an Amazon S3 bucket. Update the processing code to use Amazon S3. Configure an S3 event notification to invoke the decision Lambda function when objects are created.

Selected Answer: C
By combining Amazon ECS with Fargate tasks, AWS Lambda for the container selection logic, and Amazon S3 for event-driven processing, Option C provides a serverless and scalable solution that meets the requirements while minimizing the need for EC2 instances and leveraging the strengths of each AWS service. While this solution requires migrating the file storage from Amazon EFS to Amazon S3, it addresses the requirement of eliminating EC2 instances by leveraging AWS Fargate for the processing tasks and AWS Lambda for the container selection logic. Additionally, it utilizes the event notification capabilities of Amazon S3 to trigger the Lambda function when new files are uploaded. The other options are either not feasible due to the limitations of Amazon EFS (Options A and B) or introduce additional constraints by using AWS Lambda for the long-running data processing tasks (Option D).
