Basics

User serverless.com video and reference material, and for this initial task prefer the Node.js option.

MVP will be a tested deployment to an AWS Gateway API for demo consumption

##Later Consider

• deployment within org's AWS infra, IAMs, etc.
• Correlation ID passthrough
• Logging integration
