The article provides a comprehensive overview of Argo CD architectures as of 2025, highlighting various deployment strategies such as Hub and Spoke, Standalone, Split-Instance, and Control Plane, each with distinct advantages and challenges. Argo CD is praised for its scalability in performance, security, usability, and failover capabilities, with high-availability options supporting numerous applications and clusters. The security model is robust, featuring Role-Based Access Control and Single-Sign-On, though it acknowledges potential risks with manifest rendering. Usability is emphasized, though scaling can introduce complexity and necessitate memory tweaks. Failover considerations focus on the ease of configuration recovery. The article advises careful selection of architecture to minimize the blast radius of potential failures and discusses the benefits and drawbacks of each model, encouraging further exploration through resources like the GitOps certification and Codefresh's control plane offerings.
