This is part 2 of the blog where we are creating the Auto Scaling Group in AWS. Let's dive right in, where we left off in the last blog.

Now we are at Step 3, here we define the optional Load balancing details and Health checks. Later is something you should always have configured as a best practice.

Step 3 - Load balancing and health checks

In Step 4 we will configure the group size and scaling policies. You provide a minimum and maximum no. of instances along with a desired capacity which becomes the default no. of instances.

Step 4 - Group size and scaling policies

Scrolling down you have the scaling policies. I recommend having a "Target tracking scaling policy". There are different criteria that you can configure. In the screenshot below, you have the policy based on the average CPU utilization.

Optional scaling policies

You can configure various notifications on your auto scaling group next.


Finally, you have the option to configure tags on the auto scaling group.


Review all the settings and create the auto scaling group. That's all there is to it. Simulate some load on your application and monitor how the instances scale out and in compliance with your scaling policies.
