Run cron job in AWS

Question

Hi Team,

We are planning to run a cron job in AWS, The job will run 60 minutes every day. So we need best AWS resource to do it. 
                          1) If we use EC2, we need to spend money for rest of 23 hours.
                           2) If we use lambda, it will time out after 25 min
                           3) AWS batch also not suitable it seems.

So please suggest best option for us here

Accepted Answer

Given that you have ruled out the possibility of using AWS Batch and Lambda does not meet your requirements in terms to total time for execution, there are 2 possible options:-

1 ECS Scheduled Tasks - This would require code to be containerized (docker)

2 Automate starting and stopping of EC2 instances - This solution helps reduce operational costs by stopping resources that are not in use and starting resources when their capacity is needed.

Answer

Without knowing more details about the job you're trying to run this is a difficult question to answer. However, a few things to think about:

If the task has to run on EC2, then why not use [instance scheduler](https://aws.amazon.com/solutions/implementations/instance-scheduler-on-aws/) to run the instance and then shut it down when it is finished? That way you're not paying for the extra 23 hours a day.

An alternative might be to run the task in a container on [Fargate](https://aws.amazon.com/fargate/) and use [EventBridge](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-create-rule-schedule.html) to schedule it.
