How do I use autoscaling effectively with CloudFormation?

Using autoscaling effectively with AWS CloudFormation involves defining scalable resources in a way that allows your application to handle varying loads.

To set up autoscaling in CloudFormation, you need to create an Auto Scaling group and a Launch Configuration. The Auto Scaling group manages the scaling policies and the number of instances running, while the Launch Configuration specifies the instance type and settings.

Here’s an example CloudFormation template snippet that demonstrates how to create an Auto Scaling group with a Launch Configuration:
