EC2 vs Fargate for periodic workloads

Question

Context:

Workload will be periodic and predictable
Don't want to go with on-demand EC2 since most of the time it won't be active.

Questions:

How we can only spawn an ec2 when we need and close it after it's done with a task?
Would fargate be a better choice for this situation?

Answer

Also if the processing does not take long (less than 15 minutes), you can consider using Lambda functions - https://aws.amazon.com/lambda/faqs/

If your processing can take longer than 15 minutes, you can also consider AWS Step Functions Standard Workflows - https://aws.amazon.com/step-functions/faqs/

Both Lambda functions and Step Functions are completely serverless. You don't have to worry about provisioning any infrastructure.

Answer

[AWS Batch](https://aws.amazon.com/batch/faqs/?nc=sn&loc=5) would be highly recommended here.
