The challenge
A single-region deployment meant every cloud incident became a customer-facing outage, and releases needed a maintenance window.
Our approach
- 01
Designed active-active clusters across AWS and GCP with Istio for traffic control.
- 02
Moved every environment into Terraform with automated drift detection.
- 03
Introduced canary releases with automatic rollback on error-rate spikes.
The outcome
Uptime in the first year: 100% · Deploy time: Hours → min · Maintenance windows: 0. The Stratos Enterprise team now owns the full codebase and documentation, with Promettis on hand for ongoing improvements.
