Control multicluster costs with right-sizing in Red Hat Advanced Cluster Management 5

By · Published by Everything Blog

In short

Platform engineering and FinOps teams can now generate tailored CPU and memory recommendations across entire Kubernetes fleets. The release establishes the multicluster observability add-on and Perses dashboards as standard interfaces, replacing older policy-based delivery models. Administrators can also leverage dual metrics collection paths for metric federation or existing allowlists during monitoring. Upgrades from earlier versions occur seamlessly while automatically purging obsolete governance resources.

Red Hat Advanced Cluster Management for Kubernetes 5 makes the multicluster observability add-on (MCOA) delivery model and Perses dashboards generally available (GA) for namespace and OpenShift Virtualization right-sizing recommendations. The release also adds configurable percentile profiles for more precise CPU and memory recommendations.

For platform engineering and FinOps teams, right-sizing a fleet is a balancing act. Requests that remain well above actual use lock capacity away from other workloads and increase infrastructure cost. Requests that remain below demand can cause throttling, degraded performance, and unstable applications. The challenge grows when the same analysis must cover many clusters, namespaces, and virtual machines (VMs).

Red Hat Advanced Cluster Management for Kubernetes 2.16 made Namespace and OpenShift Virtualization right-sizing recommendations generally available. The capability used long-term metrics from the multicluster observability stack to compare actual CPU and memory use with configured requests and present the results in Grafana dashboards.

In Red Hat Advanced Cluster Management 2.17, we introduced a developer preview of right-sizing recommendations delivered by the multicluster observability add-on (MCOA) and visualized with Perses. Customers could opt in to evaluate the new…
