Jenkins’ controller‑agent model hits performance limits as organizations add pipelines, agents, and plugins, often forcing multi‑controller deployments that increase operational overhead. The article contrasts this with TeamCity’s server‑agent architecture, where a single server centralizes configuration while agents scale horizontally. TeamCity adds built‑in elasticity, cloud‑hosted agents, visual build chains, and intelligent agent matching, reducing the need for extensive plugin ecosystems. The net result is a CI/CD platform that scales more predictably with lower maintenance effort.
Plugin‑centric CI/CD platforms such as Jenkins rely on thousands of community‑maintained extensions, exposing pipelines to inconsistent security practices, abandoned code, and broad permission grants. In 2025 Jenkins alone recorded over seventy plugin‑related CVEs, including remote‑code‑execution flaws that lingered on exposed...
