Managing Kubernetes clusters at scale can be complex. As organizations expand, they often run workloads across multiple clusters—sometimes across different regions, environments, or even cloud providers. This is where Red Hat Advanced Cluster Management for Kubernetes (RHACM) becomes essential.
With RHACM, you can deploy, manage, and govern applications across multiple clusters in a unified way. And when combined with GitOps, it gives you a consistent, reliable, and automated approach to application deployment.
What is RHACM?
RHACM is a management tool from Red Hat that provides:
A single dashboard to view and manage multiple Kubernetes and OpenShift clusters
Policy-based governance and compliance
Simplified application deployment across clusters
Integration with GitOps workflows for continuous delivery
Why Use RHACM with GitOps?
🔄 Consistency – Ensure every cluster runs the same version of your app
🚀 Faster Delivery – Deploy updates automatically whenever code changes in Git
🔒 Compliance & Security – Apply cluster-wide policies with ease
🌍 Scalability – Manage apps across data centers, public cloud, and edge clusters
How Application Deployment Works with RHACM
Connect Your Clusters
RHACM brings multiple Kubernetes/OpenShift clusters under one management console.
This can include on-premises clusters, cloud-based clusters, or hybrid setups.
Define Your Application in Git
Applications are described in a Git repository (the single source of truth).
Any change in Git triggers an automated sync to your clusters.
Create an Application Placement Policy
Decide where your application should run (e.g., only in dev clusters, or in multiple production clusters).
RHACM enforces these rules consistently.
Deploy and Monitor
RHACM automatically deploys the application across the selected clusters.
You get a central view of application health and compliance.
Real-World Use Cases
Multi-Cloud Strategy – Deploy the same app on AWS, Azure, and on-prem clusters for availability.
Disaster Recovery – Run critical apps across clusters in different regions.
Development & Testing – Deploy apps to dev clusters first, then promote to production clusters.
Best Practices
Keep your Git repositories well-structured and version-controlled.
Use RHACM policies to enforce security, networking, and compliance rules.
Regularly monitor cluster health and app performance from the central dashboard.
Final Thoughts
Deploying applications in a multi-cluster environment doesn’t have to be complicated. With Red Hat Advanced Cluster Management and GitOps, you get the power of automation, consistency, and governance—all from one place.
This means faster deployments, greater reliability, and freedom to run your apps anywhere your business needs them.
