Transition to the Cloud Return
summary
A small core team migrated an application estate from an on‑prem datacenter running OpenShift and MSSQL to Azure over a rapid timeframe: they moved to AKS, Azure AD, Azure Key Vault, GitHub Actions and Terraform, using bespoke migration tools. Over ~6 weeks they migrated 100+ microservices with a bulk cutover by end‑October, cut over databases afterward, ran automated rollback scripts and dry runs in production, and entered November hypercare while implementing Zero‑Trust access, APM and stricter GDPR controls for visibility and autonomy.
