The processed tsv file will be moved to the processed folder. I dont know the best way to implement this in AWS?

Manual approach is:

You can do it without an Amazon EC2 instance:

  • Create an AWS Lambda function that will perform the process (call API and log the response)
  • Store any persistent data in an Amazon S3 bucket and have the Lambda function download/upload from there
  • Create a CloudWatch Events rule to trigger the AWS Lambda function at the desired interval

AWS Lambda functions provide 512MB of storage in the /tmp/ directory, so you can download the TSV file to there, perform your operations and then upload the resulting file back to S3.

You will only be charged for the duration that the Lambda function actually runs.
