Our version control and CI/CD pipeline infrastructure is strategically split between GitLab and GitHub platforms. While we leverage GitHub for public open-source repositories to maximize community visibility and engagement, GitLab serves as our primary platform for closed-source customer projects, particularly due to its self-hosting capabilities. This decision was influenced by reliability concerns with our customer's on-premise GitLab installation and limited access to critical configuration sections due to security restrictions.
The dual-platform approach has proven to be effective, with GitLab demonstrating superior performance characteristics in our enterprise deployments. While both platforms serve their intended purposes well, our team has observed better performance metrics with GitLab compared to GitHub, particularly in terms of response times and overall system stability. This experience continues to validate our platform selection strategy, although it's worth noting that this architecture was established as part of our organization's longer-term technical strategy.
