Jenkins was designed around a single controller architecture, which creates bottlenecks as organizations scale. Two common strategies—centralizing everything on one powerful controller or splitting across multiple controllers—each come with tradeoffs: single points of failure vs. instance sprawl and configuration drift. Plugin management compounds the problem at scale, requiring dedicated operational effort. Modern CI/CD platforms like TeamCity address these challenges through server-agent separation, built-in integrations, and centralized governance, reducing the operational overhead that Jenkins accumulates at enterprise scale. A comparison table and evaluation criteria for choosing a CI/CD platform are provided.
