Recovery Time Cut by 98% Through Automated Domain Management  

Rather than implementing a temporary fix, we built a solution that eliminated the root cause of the problem and made future domain blocks fast and easy to manage. The work focused on three key areas.

Platform Stabilization

We quickly restored the service to minimize the business impact of the incident.

Eliminating Architectural Dependencies

We analyzed the entire system, identified every location where the domain was tightly integrated, and removed those architectural dependencies.

Automated Domain Management

We developed the Domain Management Platform, a dedicated management layer that applies domain changes automatically at the infrastructure level. Adding, replacing, or switching a domain can now be completed with a single click in about five minutes, without modifying the application code or involving the technical team.

How We Eliminated the Dependency on a Single Domain

The Domain Management Platform is a fully custom solution designed and built from scratch. It automates domain configuration management and the application of changes across different infrastructure components. The system separated domain management logic from the platform's internal components and eliminated the need to manually modify application code, the database, or configurations every time a domain changed.

The platform became a dedicated management layer responsible for applying changes at the infrastructure level. Instead of searching for and updating dozens of dependencies, the team gained a standardized process where all operations are performed automatically according to predefined rules.

To implement this, we used Amazon CloudFront, where flexible routing and request-processing rules were configured. This made it possible to control traffic behavior at the content delivery network level and apply the required changes without rebuilding the application.

We also used Istio EnvoyFilters for dynamic payload rewriting at the service mesh level. This made it possible to modify the required data while requests were being processed without changing the application code, making the domain-switching process independent of the system's internal logic.

As a result, the domain replacement process was transformed from a manual operation with multiple dependency points into a standardized, automated workflow.
