Скачать или смотреть Argo CD hub and spoke model risks explained

When one team revealed they're running 30,000 applications on a single Argo CD instance, it sparked an important discussion about the security tradeoffs of hub-and-spoke architectures.

The setup: One central Argo CD instance managing deployments across multiple Kubernetes clusters - a classic hub-and-spoke model that seems elegant on the surface.

The problem: This architecture creates a single point of failure from a security perspective. If an attacker gains access to that one central Argo CD instance, they effectively have the keys to every vault - access to all your clusters and applications.

This is why many organizations are moving away from hub-and-spoke models despite their operational simplicity. Yes, it makes management and observability easier when everything goes through one place, but it significantly increases your security risk profile.
