Centralized Power: How TeamCity's Architecture Solves Jenkins' Scaling Problem | The TeamCity Blog
Blog post from JetBrains
Jenkins, a widely used CI/CD platform, often encounters scaling challenges as its architecture requires careful management of controller load, plugin compatibility, and governance, leading to increased operational overhead in larger installations. Jenkins uses a controller-agent model, where multiple controllers may be necessary to distribute load, but this comes with additional complexities in plugin management and maintaining consistent configurations across instances. In contrast, TeamCity offers a server-agent architecture that centralizes orchestration and configuration, allowing for horizontal agent scaling and reducing the need for extensive third-party extensions. TeamCity's built-in features, such as visual build chains and intelligent agent selection, enhance scalability and maintainability, providing a more streamlined and predictable experience for DevOps teams. This centralized approach can alleviate the operational burden associated with Jenkins, especially for organizations experiencing growth in their CI/CD requirements.
