Cloudformation

• we write templates and to execute the template we create stack
• components
  • resources
  • parameters
  • outputs
• LEts create a vpc with 2 subnets and two ec2 instances
  
• Execute template Refer Here for changes done
  
  

ARM (Azure Resoure Manager) Templates

• Refer Here for the extension to vscode
• Refer Here for creating arm templates from vscode
• Refer Here for ARM Template reference
  
• Refer Here for resource manager
• ARM templates are written in json format Refer Here for sample template with network and two subnets
• Azure Bicep is a new format for deploying templates with dsl
