This is not your typical AWS reference course. You won’t find most of the knowledge that's shared here in the AWS docs. The goal here is to help you realize which AWS features you’d be foolish not to use — features that have passed the test of time by being at the backbone of most things on the Internet.

In this course, you'll learn a technique used to help make reliable technical choices without getting paralyzed in the face of so many options. You’ll start by going through the most fundamental services AWS offers such as DynamoDB, S3, EC2. Each section breaks down how it’s used, the pros and cons, why you should (or shouldn't) be using it, and more.

This course was written by a former Amazon engineer with 15 years of experience working on AWS.

The Good Parts of AWS: Cutting Through the Clutter

# Objective
- Replace explicit EC2 instances with Auto Scaling.

# Steps

- Remove `Instance` and `Instance2`.

---

# Removing the explicit instances

Now that our new ASG instances are up and are serving requests through our load balancer, we can safely remove our explicit instances without causing any disruption. To do so, we just need to remove every reference to them from our `main.yml` script, and redeploy:

* The entire `Instance` resource.
* The entire `Instance2` resource.
* The entire `Targets` property from the `LoadBalancerTargetGroup` resource.
* The `Ec2TagFilters` property from the `StagingDeploymentGroup` resource.
* The `InstanceEndpoint` and `InstanceEndpoint2` outputs.

Now, let's redeploy our infrastructure by running `deploy-infra.sh`.
