PreBake AWS AMIs for Auto Scaling
Welcome to this hands-on AWS Learning Activity in which you will learn how to create Pre-Baked AMIs for the purpose of simplifying EC2 instance provisioning in an Auto Scaling environment.
When provisioning EC2 instances it is often necessary to bootstrap these instances to configure software on the instances at launch time. But this often can be a time consuming task and delays the instance being in a ready state. Pre-Baking AMIs with already installed software is a technique to ease the burden of bootstrapping and to decrease the time it takes to launch and provision EC2 instances. Pre-baking can be especially helpful in deploying EC2 instances in Auto Scaling groups. The Pre-Baked AMI can be part of the launch configuration for the Auto Scaling group.
