Automating Infrastructure with AWS CloudFormation (IAC)

Deploying infrastructure in a consistent, reliable manner is difficult. It requires people to follow documented procedures without taking any undocumented shortcuts. It can also be difficult to deploy infrastructure after hours when fewer staff are available. AWS CloudFormation changes this situation by defining infrastructure in a template that can be automatically deployed—even on an automated schedule. In this lab, you learn how to deploy multiple layers of infrastructure with AWS CloudFormation, update a CloudFormation stack, and delete a stack (while retaining some resources). After completing this lab, you should be able to do the following: Use AWS CloudFormation to deploy a virtual private cloud (VPC) networking layer. Use AWS CloudFormation to deploy an application layer that references the networking layer. Explore templates with AWS CloudFormation Designer. Delete a stack that has a deletion policy.
