Learning Objectives
CloudFormation is a powerful AWS service that allows you to define and provision AWS infrastructure as code. CloudFormation templates allow you to define your AWS infrastructure using JSON or YAML in a declarative template format. Using CloudFormation templates ensures that your infrastructure is provisioned consistently across different environments (e.g., development, staging, production). Creating and managing templates can sometimes be challenging. This Cloud Lab discusses common issues and errors that might arise during template creation and deployment.
In this Cloud Lab, you will deploy a CloudFormation template with a VPC with two subnets, two EC2 instances, a NAT Gateway, and an S3 bucket. The EC2 instances will host the web application. The template will initially contain some errors, which you will troubleshoot step by step during the Cloud Lab. You will be using CloudFormation events, the cfn-signal helper script, the DependsOn attribute, and cfn-init logs to troubleshoot the infrastructure.
By the time you finish this Cloud Lab, you’ll be able to detect and resolve infrastructure problems in a CloudFormation template using CloudFormation events, the DependsOn attribute, and cfn-init logs.
The provisioned infrastructure by the end of this Cloud Lab is shown in the illustration below:

Your method is simple, straight to the point and I can practice with it everywhere, even from my phone, that's something I have never had in other learning platforms.
I highly recommend Educative. The courses are well organized and easy to understand.
I prefer Educative courses because they have a nice mix of text & images. I find that with full video courses, it can often be too easy to go into passive learning mode.
