Kubernetes: adoption, upgrades and operations

Your applications on AKS, EKS or GKE. Step by step, with GitOps, monitoring and a runbook for every service.

What we do

  • Honestly assess whether Kubernetes makes sense for you. For many companies a simpler platform is the better choice, and we’ll tell you so.
  • Build or fix the cluster (AKS, EKS, GKE) as code, with separate environments, network policies and identity management.
  • Package applications into containers and Helm charts and deploy them via GitOps. The cluster state matches what’s in Git.
  • Set up monitoring, alerts, autoscaling and backups. Every application gets a runbook: what to do when something breaks.

What you get

  • A cluster that survives a node failure and an upgrade. Verified, not assumed.
  • Deployment through Git. A change in the repository propagates to the cluster on its own, including rollback.
  • Visibility into cost and performance. Which services cost how much and where there’s room to scale down.
  • A team that can run it. Documentation and a workshop so the cluster isn’t a black box.

How we work

We start with an assessment using read-only access. Within a week you know what state the cluster is in and what needs doing. Upgrades and migrations are done in waves, always outside production first and with a prepared way back. Production changes only in an agreed window.

Typical engagements

Scope and price are agreed upfront. Most engagements fit into days and weeks, not months.

Cluster assessment

Scope: 1 week

Deprecated APIs and Helm charts, add-on compatibility, resilience to node failure, security and cost. The output is an upgrade or remediation plan with a fixed price.

Zero-downtime upgrade

Scope: 2–3 weeks

First we fix what would block the upgrade. Then non-production, then production in waves in your maintenance window, with a prepared way back.

Kubernetes adoption

Scope: 6–8 weeks, up to 3 applications

Containers, Helm charts and GitOps with ArgoCD. Applications moved in waves with a pilot and a parallel run, plus monitoring and a runbook for each of them.
