Which formats can AWS Cloud Formation Templates be in?

AWS CloudFormation Templates can be created in either JSON or YAML format. Both of these formats are widely used for configuration files and are well-suited for defining the infrastructure as code in AWS CloudFormation.

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is commonly used in programming with a variety of languages and is a standard format for many APIs.

YAML (YAML Ain't Markup Language) is another human-readable data serialization format, which is often considered more user-friendly than JSON. YAML tends to be easier to read and write for many users due to its indentation-based structure and support for comments, making it particularly popular among DevOps and infrastructure automation professionals.

The flexibility of using either JSON or YAML allows developers to choose the format that best fits their needs or preferences when defining stacks in AWS CloudFormation. This choice enhances usability and accessibility when managing various AWS services and infrastructure, helping teams implement and manage resources more effectively.
