You can use AWS Lambda to automate the start and stop operations of EC2 instances. This can be useful for cost optimization by ensuring that instances are only running when they are needed. Here's an overview of how to achieve this:
Create Lambda Functions:
Start EC2 Instances Lambda Function:
Create a new Lambda function.
Choose a runtime (e.g., Python, Node.js, etc.).
Add the necessary permissions to your Lambda function to interact with EC2 instances.
Write the code to start the desired EC2 instances. You can use the AWS SDK for your chosen runtime to interact with EC2 instances using APIs like start_instances.
Stop EC2 Instances Lambda Function:
Create another Lambda function following similar steps.
Add the necessary permissions for stopping EC2 instances.
Write the code to stop the specified EC2 instances using the appropriate SDK method, such as stop_instances.
