KUBERNETES

Kubernetes and Amazon EKS production consulting

RTZ Labs provides Kubernetes consulting for production environments – reviewing cluster architecture, workload reliability, scaling behavior, and day-2 operations, with a focus on Amazon EKS.

A Kubernetes cluster that worked at one scale often stops working at the next, and the reasons are usually structural: resource requests that were guessed once and never revisited, disruption budgets that block node rotation, autoscaling that reacts to the wrong signal, or upgrade debt that has compounded. We review clusters against how they behave under real load and failure, not against a checklist.

All expertise

What we do with Kubernetes

Review cluster architecture, node group design, and multi-AZ failure domains
Analyze workload reliability – resource requests and limits, probes, disruption budgets, and eviction behavior
Diagnose scheduling and autoscaling problems, including Cluster Autoscaler and Karpenter behavior
Assess and plan Kubernetes and EKS version upgrades, including API deprecation impact
Establish workload guardrails and paved-road patterns product teams can adopt by default
Investigate control plane throttling, API server pressure, and the client behavior that causes it
Review cluster networking – CNI, ingress, DNS, and the traffic path to your services

Problems we are called in for

Usually described this way before anyone knows the cause.

The cluster has grown organically and namespaces have become snowflakes

Pods are evicted or OOM-killed under load and the limits were never revisited

Node upgrades stall or drain unsafely

Autoscaling reacts too slowly, or scales on a metric that does not track real demand

Version upgrades have been deferred and the gap is now uncomfortable

Developers need a platform engineer to ship anything new

Scope and boundaries

Our primary focus is Kubernetes on AWS, particularly Amazon EKS. We work with other managed distributions, and will say plainly where our depth is lower.
