All software and infrastructure changes are gradually promoted through four rings based on rigorous test-driven checkpoints. The four rings are:
-
Dev
-
QA
-
Preview
-
Production (Prod)
-
-
After approval, all deployments use automation to reduce the risk of human error and improve reliability for customers.
-
Services are upgraded automatically without downtime for customers.
-
Change management is traced through work item tracking systems.
-
Only Cloud Operations employees have access to the Production ring infrastructure.
-
Hexagon Services and Presales teams use the Preview ring for configuration and demonstrations.
-
No Hexagon employees have access to customer Production tenants.
