Nested CloudFormation Stack: a guide for developers and system administrators
AWS’s CloudFormation is widely used by developers and system administrators and it’s not hard to see why. CloudFormation helps you to provision your AWS resources in a predictable order, allowing you to easily configure dependencies and run-time parameters. The collection of AWS resources provisioned by CloudFormation is known as stack.
Nested CloudFormation stacks
Nested stacks are AWS CloudFormation stacks inside stacks. These nested stacks under the main stack are considered as a resource. To more easily understand, let’s call child templates “functions,” and let our main stack act as an entry point for calling those functions.
CloudFormation and dependencies
However, Jeff was still worried about parallel provisioning of resources as there are some environment dependencies, but later he found that wherever there was a dependency that one child stack should come up before another child stack, he can use DependsOn attribute or GetAtt function.
