Centralized Power: How TeamCity's Architecture Solves Jenkins' Scaling Problem

A comparison of Jenkins and TeamCity CI/CD architectures focused on scaling challenges. Jenkins at enterprise scale often requires multi-controller setups, careful plugin management, and significant operational overhead. TeamCity's centralized server-agent model addresses these issues by keeping configuration centralized while scaling execution horizontally through build agents. Key TeamCity advantages covered include elastic cloud agents, visual build chains with dependency graphs, intelligent agent selection based on capabilities, and fewer third-party plugin dependencies. A detailed comparison table covers architecture, scaling strategy, plugin dependence, orchestration, agent management, workload placement, and maintainability.
