Overview

The ESP Deployment Pipeline project is an effort to automate the deployment of the ESP application suite (built by ESS) into customer environments using Azure DevOps (AzDO) YAML pipelines and PowerShell scripts.

We are the third team to inherit this work. Team Ludo started it, got the build working in AzDO, and began deployment work before being reassigned. We pick up from there.

Context — Why This Project Exists

Few original ESS engineers remain; those left are on paid customer work
Manual deployments are slow, risky, and rely on tribal knowledge
Business goal: all deployments are consistently repeatable with no manual VM work
Initial scope: ROMAC DEV environment only
Future scope: all environments including PROD and ESS's own data centre
