Kubernetes Infrastructure Migration

We containerise the workloads on your servers and migrate them wave by wave to a Kubernetes platform built with security and observability standards. On-prem, cloud or hybrid: the platform is yours, the discipline is ours.

Why now

If these symptoms sound familiar

  • Servers are set up by hand; no two environments are exactly alike.
  • Capacity has to be added manually during traffic spikes; night-time calls are increasing.
  • A package that works in test behaves differently in production.
  • High availability relies on expensive and complex solutions.
  • The cloud bill keeps growing, but nobody can see which workload spends what.

Highlights

  • Amazon EKS, Azure AKS, Google GKE, OpenShift and on-prem
  • GitOps-based delivery with Argo CD
  • Autoscaling and high availability
  • Monitoring with Prometheus, Grafana and OpenTelemetry

Scope

Scope and deliverables

Every item is adapted to the scope and priorities agreed together after the assessment.

  1. 01

    Readiness assessment

    Workload inventory, dependencies, state (stateful / stateless) and compliance requirements; a migration-wave plan.

  2. 02

    Platform design

    Cluster topology, environment strategy (dev / test / prod), networking (CNI, ingress, service mesh), storage (CSI), identity and access management.

  3. 03

    Containerisation

    Dockerfile standards, image security (scanning and signing), packaging with Helm charts or Kustomize.

  4. 04

    GitOps and CI/CD

    Declarative delivery with Argo CD or Flux; promotion across environments; secret management with Vault and External Secrets.

  5. 05

    Security and compliance

    RBAC, Pod Security standards, NetworkPolicy, policy enforcement with Kyverno / OPA and audit logging.

  6. 06

    Observability and SRE

    Prometheus, Grafana, Loki and OpenTelemetry; SLO definitions, alerting rules and on-call runbooks.

  7. 07

    Migration and cutover

    Wave-by-wave migration, parallel running, controlled traffic shifting and a rollback plan for every wave.

  8. 08

    Cost optimisation

    Right-sizing, HPA / VPA / Cluster Autoscaler, mixed node pools and FinOps reporting.

Outcomes

What changes after the transformation

Autoscaling

Capacity grows on its own when load rises and cost falls when it drops.

Self-healing workloads

Unhealthy containers restart automatically; workloads move when a node is lost.

Consistent environments

Dev, test and production derive from the same definition; "it worked on my machine" is over.

Visible cost

Resource usage is reported per namespace and team; optimisation becomes continuous.

FAQ

Frequently asked questions

Can stateful applications such as databases be migrated too?

Yes, but we assess each one separately. Some databases are better run on Kubernetes with operators, others on managed cloud services or on their existing servers.

Is Kubernetes possible in our own data centre?

It is. We build on-prem and hybrid platforms with OpenShift, Rancher or kubeadm-based installations, without creating dependency on a cloud provider.

Will our existing CI/CD pipeline be preserved?

Largely, yes. Your existing tools such as Jenkins, GitLab CI, Azure DevOps or GitHub Actions keep building images; the deployment layer is standardised with GitOps.

Will there be downtime during migration?

Our target is zero downtime. Workloads move in waves, old and new environments run in parallel for a while and traffic is shifted in a controlled way; every wave has a rollback plan.
