Existing application running on a fleet of EC2 spot instances

Question

Hello,

Can somebody tell me the right option for the below question?

The customer has an existing application running on a fleet of EC2 spot instances. This application processes millions of messages from SQS and generates CSV to be stored in s3. Customer is considering to move to ECS farget. What changes will be needed?

a. Continue to use spot instances and bundle the app as a docker image.
b. moving to containers is not recommended because containers will add overheads
c. consider using the self-launch mode to migrate the existing ec2 instances to farget launch mode
d. use DMS service to port the application

Answer

The correct option is (a) Continue to use spot instances and bundle the app as a docker image. The customer can migrate their application to ECS Fargate by packaging their application into a Docker container image, which can be run on Fargate instances. This will allow the customer to take advantage of Fargate's managed infrastructure and eliminate the need to manage EC2 instances.
