Did you know you can use CloudFormation to manage third-party resources? The AWS CloudFormation Public Registry provides a searchable collection of CloudFormation extensions and makes it easy to discover and provision them in CloudFormation templates and AWS Cloud Development Kit (CDK) applications.
AWS Partner Network (APN), third parties, and the developer community contribute these extensions to the Public Registry.
After creating a resource from a third-party resource type, CloudFormation will detect changes to the third-party resource from its template configuration, known as configuration drift, just as it would with AWS resources.
This will show you a list of available third-party resources in your region (note that different regions may have a different set of third-party resource types).
