This is now deprecated and won't be developed further. Use the following solution by AWS: https://aws.amazon.com/answers/infrastructure-management/instance-scheduler/

This service was created to automatically stop the development resources during nights and weekends so you don't have to pay for their use.

There's a regular schedule for triggering a Lambda script that checks all the resources for Nightly tag key. The value is UTC offset which allows you to set when people using them are in work.

For now only statically defined start and stop hours. Start at 7 and stop at 18. Can be changed by rewriting the script.

Tag the supported resource with key Nightly. Use the required timezone offset as value. For example:

If there are multiple teams using the resource, you can use multiple offsets separated by comma. If there's at least one offset that matches the running hours of resource during the check, it's left running.

• EC2 (outside ASG)

• CloudFormation deployment
• support more services (RDS, ASG...)
• configuration in DynamoDB
• be stateful (don't start what wasn't running)
• tests
