How Iterative Infrastructure Fixes Tamed a Chaotic 20-Service Gamedev Stack

A growing game development project running nearly two dozen services across Python, Go, C++, and a mobile client had accumulated deeply inconsistent infrastructure, with each service deployed differently and configurations stored directly on servers. Rather than attempting a disruptive full-scale refactoring, the team adopted an iterative approach where each small change delivered immediate value without breaking existing workflows. Centralized CI templates were introduced so that a single fix could propagate across all services, and configuration management was split into static configs handled via a dedicated repository and runtime configs managed through a GitOps workflow with schema validation. Secrets previously scattered across CI variables and server files were consolidated into a dedicated secrets manager, reducing both security risk and operational confusion. The overarching principle guiding the sequence of changes was to establish observability first — logs, metrics, and alerts — before restructuring anything else.
