Automatically change AWS EC2 instance size with Lambda

AWS Auto Scaling enables the automatic scaling of EC2 instances by launching and terminating instances. This is known as horizontal scaling, or scaling out. Sometimes, we want to scale vertically (or "up").
AWS does not provide an automated service to manage this process but we can create our own solution using the EC2 API and some custom code. In this video, you'll learn how to automatically scale an instance vertically using an AWS Lambda function that runs some Python code and modifies the EC2 instance type.

You're an amazing teacher, if I have the chance, I'll do all of your Udemy courses.

Can we factor in zero downtime in this ? By building the launch configuration template and replacing the instance, waiting till the old gets drained and new instance is launched.

[@DigitalCloudTraining]

There will be some downtime while the old instance fulfills existing requests before terminating.

thanks for share! :)

Could you add multiple ec2 instances to this code? I need to update about 50 servers to the same server type and want to do it in bulk
