AWS Cloudformation contd

• linked templates or nested templates Refer Here
• For complex infrastructures Using nested stack is recommended Refer Here
• Terraform modules are much flexible compared to cf nested stacks
• count doesnot exist in cloud formation Refer Here
• Can the resources be imported => yes (refer classroom video)

Exercise:

• Create a dynamo db table with Partition key LockID in cloud formation.
  • with name of table
• Create an s3 bucket
  • with name of bucket
• Call the template as backend.json
