I've used JSON & YAML to coordinate AWS Cloud Development. They're OK. 

I've started looking into their "new-ish-to-me" CDK which allows the use of programming languages to coordinate AWS resources. Its great in that (I feel) it offers a more expressive way to build and deploy SaaS applications to AWS.

Be sure to follow the v2 CDK examples

• https://aws.amazon.com/cdk/

• https://marketplace.visualstudio.com/items?itemName=AmazonWebServices.aws-toolkit-vscode

  • You can run "cdk synth > template.yaml" to translate from CDK to this GUI-based composer.

  • Conversely you can use the CDK migrate tool to translate from your yaml template to your CDK high-level language of choice.

  • Remember to include --profile <your profile> after the cdk command if you're setup with multiple profiles in your environment

To note that if you're using AWS SSO there can be issues with authentication when running CDK. This article has good notes and a nice python script to help manage this pain point.

This is an amazing tool for docker/kubernetes and microservices coordination and deployment.
