Hello SAS Community, We are in the process of moving some services to the AWS cloud and have around 8 SAS instances running. Our goal is to create an automation script to shut these instances down during off-hours to save costs. Here are a few specific questions we have: Shutdown Mechanism: When shutting down an EC2 instance using AWS commands, does it perform a graceful shutdown similar to a normal OS shutdown, or is it more like pulling the power cord? Shutdown Order: Is there a best practice for the order in which to shut down and start up instances? For example, should databases be shut down last and started first? Automation Tools: What are the recommended tools or methods for automating this process? We've looked into AWS Lambda and AWS Systems Manager but would appreciate guidance or examples. Handling Dependencies: How do we ensure that dependent services are shut down in the correct order to prevent issues? Here is what we are currently considering: Using AWS Lambda triggered by CloudWatch Events to stop instances. Ensuring that our shutdown sequence handles dependencies correctly (e.g., web servers -> application servers -> databases). Any insights, best practices, or sample scripts would be greatly appreciated! Thanks in advance for your help!
