AWS Service Catalog Introduces Support for YAML-formatted AWS CloudFormation Templates
You can now create Service Catalog Products using YAML-formatted AWS CloudFormation templates (YAML Version 1.1) in addition to JSON-formatted templates. This allows template creators to choose the format they feel most comfortable working in to describe AWS infrastructure. YAML-formatted CloudFormation templates follow the same anatomy as existing JSON-formatted templates.
You can also view the CloudFormation documentation topic for YAML-formatted templates here. Visit here for an introduction to CloudFormation template basics.
AWS Service Catalog is currently available in the US East (N. Virginia, Ohio), US West (Oregon), Canada (Central), Europe (Ireland, Frankfurt, and London) and Asia Pacific (Sydney, Singapore and Tokyo) Regions. For more information, see the AWS Service Catalog product page.
