AWS CloudFormation

AWS CloudFormation - is a service that enables users to describe and represent infrastructure resources in the cloud with just a few lines of code. The service allows you to use programming languages or text files to build models and provide all the necessary resources for the application to run in any Region or under any account, automatically and securely. The AWS CloudFormation service is free, and you only pay for the AWS resources needed for your application.

AWS CloudShell - In this workshop, we will use AWS CloudShell instead of Cloud9. CloudShell is a browser-based shell that comes pre-integrated with the AWS CLI and necessary tools. Using CloudShell brings many benefits: fast initialization (no need to wait for EC2 instances to boot up), completely free, requires no network configuration (VPC/Subnet), and most importantly, automatically inherits the IAM permissions of the currently logged-in user, making the practice process simpler and safer.
