# Day 44 : Implementing Auto Scaling for High Availability in AWS

Welcome to Day 44. Today, we will learn how to implement auto scaling for high availability in AWS. In this lab, you need to create a launch template named **datacenter-launch-template**, define a User Data script, create an Auto Scaling Group named **datacenter-asg**, create a target group named **datacenter-tg**, and create an Application Load Balancer named **datacenter-alb**. In this lab, you can't use the t2.micro instance type because it is no longer supported for Amazon Linux 2 AMI. So, I used the t3.micro instance type instead.
