Most teams either start from a blank file and guess the architecture as they go (Greenfield), or they stare at a legacy codebase and hope GitHub Copilot figures out what it should become (Brownfield). Both approaches leave enormous value on the table. Spec-Driven Development changes the game: you define the contract first, then let Copilot and Spec2Cloud generate, validate, and deploy the implementation.

In this full-day hands-on workshop, you will learn and practice the full Spec-Driven Development workflow using GitHub Copilot and Spec2Cloud — covering both Greenfield and Brownfield scenarios. In the morning we build a new cloud-native application from scratch: starting with an OpenAPI spec authored with Copilot, generating the implementation skeleton with Spec2Cloud, and iterating with Copilot agents until we have a tested, deployable service. In the afternoon we tackle Brownfield: we take a real legacy application, use Copilot to reverse-engineer its implicit contract into an explicit spec, then drive a structured modernization using Spec2Cloud to produce a cloud-ready target.

By the end of the day you will have hands-on experience with both flows, a reusable methodology for your team, and working code you can adapt immediately.
