AWS CloudFormation Template Formats

You can write AWS CloudFormation templates in JSON or YAML formats.

I love using Cloudformation to define infrastructure, create resources quickly. Cloudformation has varuious benefits:

• Version control your infrastructure
• Predictably and reliably deploy infrastructure at speed
• Perform testing on different environmentiont easier than ever.

Infrastructure as code has a huge promise.

What language is this code written in?

There are 2 options for you to write cloudformation templates.

1. JSON: this use to be the only option until AWS introduced YAML support to write cloudformation templates
2. YAML:

• Human friendly readable syntax.
• You can write comments on a YAML cloudformation template using #
• No Brackets , but indentation
