Description
We have many EC2's used for development purposes.
EC2's with tag "Stack" equal to "Develop" are all used for development purposes only.
To save money, we should change their status to "Stopped" at the end of very workday - 6:30 pm Easter Standard Time.
Currently, Dr. Loraine manually does this - when she remembers to do it.
We need an automated approach instead.
A lambda function attached to the Loraine Lab account would probably be the best approach - it is simple and relatively easy to set up.
For example, according to this documentation – https://aws.amazon.com/premiumsupport/knowledge-center/start-stop-lambda-cloudwatch/ – you can create a lambda function that would then be triggered by a timer configured in cloudwatch.
Alternatively, you can do something like this - read: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/UsingAlarmActions.html#AddingStopActions
For this task, investigate the best way to automate stopping ECs with Stack equal to Develop. It should be super simple and easy for Dr. Loraine to manage and maintain.
Give an overview of the solution here.

Thank you very much for the explanation. It is very helpful!
Confirming: EC2s in the loraine lab account got shut down at the proper time via cloudwatch.
Thank you Chirag Chandrahas Shetty for the very helpful code!
need to update cloudwatch for daylight savings time
[~aloraine] We can change the string in step 3 from "30 22 * * ? *" to "30 23 * * ? *".
Thank you - it is done!
For review, can you ask one of the other students to try doing this in their account?
