Stop searching, start operating: Scale hybrid clusters with Red Hat Advanced Cluster Management for Kubernetes 2.16

If you’ve been following our journey from elevating multicluster operations in 2.12 to expanding hybrid cloud reach in 2.13, then you know our goal has always been unified control. However, as fleets grow, "unified" can quickly turn into "crowded." In our previous 2.15 update, we focused on helping you see more and click less. With Red Hat Advanced Cluster Management for Kubernetes 2.16, we're moving beyond mere visibility into intelligent, self-service operations that work for your entire team.

Here are the four ways 2.16 helps you reclaim your nights and weekends.

1. Mobility without boundaries: Live migration of virtual machines

In Red Hat Advanced Cluster Management 2.15, we overhauled the virtualization perspective so you could find virtual machines (VMs) faster. Now we're making them move. Virtualization cross-cluster live migration is now Generally Available (GA). Instead of a VM being anchored to a single cluster, you can move them between clusters and namespaces using the command-line interface (CLI) or API.

The benefit: You can balance your fleet's load and perform maintenance without application downtime. This brings the flexibility you love about local VMs to your entire multicluster fleet. Moving a workload is as simple as a few clicks. No downtime, no drama.

2. Scale your infrastructure with total freedom.

Fluidly move your bare-metal clusters between hubs without ever losing your configuration or GitOps state. You can evolve your environment as fast as your business grows while keeping everything exactly where you need it. With our new hub cluster migration capability, you can transfer fully provisioned, bare-metal clusters from one hub to another while maintaining every bit of your configuration and GitOps state.

The benefit: You can deploy a new hub in parallel and migrate clusters gradually, helping eliminate the risk of a single in-place upgrade failure.

The "so what?": If a migration hits a snag due to infrastructure issues, the system includes built-in automatic rollback to keep your clusters safe. 

The result: You get zero-disruption upgrades and the ability to redistribute load across your control plane whenever you need to optimize capacity. 

Uniform security at scale: Centralizing role-based access control (RBAC) and GitOps delivery

Managing ten clusters is a task. Managing hundreds without controls and consistency is a nightmare. Red Hat Advanced Cluster Management 2.16 introduces the ArgoCD add-on to streamline how your workload deployments scale.

• Zero-friction GitOps: We've created out-of-the-box add-ons for installing the GitOps operator and agents. This means automated, consistent content delivery across your fleet without the manual overhead.
• Precision control: We've also brought virtualization and search RBAC to GA. Now you can centrally manage user permissions across search, applications, and VMs from the hub itself.

The benefit: Your site reliability engineer (SRE) gets a playbook for success, helping ensure that everyone from the developer to the operator has exactly the access they need and nothing they don't.

3. Stop the "just in case" resource waste

We all know the fear of under-provisioning, which usually leads to the expensive habit of over-provisioning.

• Right-sizing for VMs: We've graduated our right-sizing recommendations to GA. By leveraging Prometheus recording rules, Red Hat Advanced Cluster Management now provides CPU and memory recommendations at the VM, namespace, and cluster levels.

The benefit: You get high-level visibility for strategic resource planning. No more guessing…just data-driven optimization that reduces capital expenses and helps increase company revenue.

One more thing: Meet your new AI assistant (Tech Preview)

Ever wished you could just ask your fleet a question? We're introducing AI-enabled search through a model context protocol (MCP) server in Technology Preview. This prototype allows external AI models (like LLMs) to consume ACM search data.

The dream: Natural language queries and AI-driven workflows that allow you to manage your Kubernetes fleet by simply having a conversation.

Manage your Kubernetes fleet from a unified control plane

Red Hat Advanced Cluster Management 2.16 is designed to be the central nervous system for your hybrid cloud whether you run Red Hat OpenShift or other CNCF conformant Kubernetes distributions. By focusing on the speed and control your team actually needs, we’re helping you turn complex infrastructure into a competitive advantage.
