This way of working does come with its own set of challenges. Typically organizations have had to make compromises when deploying Argo CD in varying topologies depending on their specific priorities (for example, management or scalability). But multi-cluster deployments just got easier to manage and secure with the Argo CD Agent in Red Hat OpenShift GitOps. A new addition to the GitOps operator, the agent is part of the Red Hat OpenShift Platform Plus (OPP) subscription. Broadly, there are two common topologies for implementing Argo CD. The first is centralized, in which a single Argo CD instance runs in a management cluster and is responsible for deploying resources across a fleet of OpenShift or Kubernetes clusters. This provides for a single pane of glass which simplifies management, but can become challenging to scale as the number of applications and clusters grow. The other common topology is distributed, in which Argo CD is distributed across the fleet of OpenShift or Kubernetes clusters. This provides increased scalability, but also increases the complexity of provisioning and managing those instances. Scale has become the major blocker for large production implementations. It's not just Argo CD's performance that's important.
