3. Easy Debug
4. Scalable
5. Fast

Steps to Create Ubuntu VM

1. After Downloading the Terraform 64 bit and extract to C:\
2. create a new folder in your pc and cd to the folder, create a new ‘main.tf’ file with vscode and paste the below code
3. run the code with ‘C:\terraform.exe ’
4. if issue arises login to azure with ‘az login’
5. Once vm Creation is done use putty to connect with ip and username, password

To use Terraform copy and paste the below code to your file
