Kubernetes & Container Orchestration — Scale Without Limits

Kubernetes is the industry standard for running containerized workloads at scale. WebDirect designs, deploys, and manages production-grade K8s clusters on AWS EKS, Google GKE, and Azure AKS. Our engineers hold CKA certifications and have orchestrated infrastructure for fintech, SaaS, and e-commerce platforms — from 3-node development clusters to 50-node production deployments.

What is Kubernetes?

Kubernetes (K8s) is an open-source container orchestration platform originally developed at Google that automates deploying, scaling, and operating containerized applications. Instead of manually managing individual servers, Kubernetes declares your desired state (5 replicas of service X, minimum 2GB memory each) and continuously reconciles reality to match it. 96% of organizations are using or evaluating Kubernetes according to CNCF's 2024 survey, and CKA/CKAD/CKS certifications appear in over 3,000 global job postings — making Kubernetes expertise one of the most in-demand DevOps skills of 2025–2026.

Why Your Business Needs Kubernetes

Auto-Scaling Under Load

Kubernetes Horizontal Pod Autoscaler (HPA) and Cluster Autoscaler add capacity within seconds during traffic spikes and remove it when demand drops — you pay only for actual usage.

Zero-Downtime Deployments

Rolling updates, blue-green deployments via Argo Rollouts, and readiness probes ensure new versions are fully healthy before traffic is shifted — eliminating deployment-induced downtime.

Self-Healing Infrastructure

Failed containers are automatically restarted. Unhealthy nodes are drained and replaced. Failed pods are rescheduled. Kubernetes continuously works to maintain your declared desired state.

Multi-Cloud & Hybrid Portability

Kubernetes runs identically on AWS EKS, Google GKE, Azure AKS, or bare metal — preventing cloud vendor lock-in and enabling hybrid cloud strategies at the application layer.

Efficient Resource Utilization

Resource requests and limits allow bin-packing multiple services on shared infrastructure — typically reducing server costs by 40–60% vs. dedicated VMs per service.

Industry Standard for Microservices

96% of enterprises using containerization are using Kubernetes. Teams, tools, and job candidates expect Kubernetes — building on it ensures compatibility with the entire cloud-native ecosystem.

Our Kubernetes Delivery Process

01

Containerization Assessment

Evaluate which applications benefit from containerization, which need refactoring, and which are unsuitable. Create a migration roadmap.

02

Cluster Architecture Design

Node sizing and instance type selection, CNI plugin choice (Calico for network policies, Cilium for eBPF performance), storage class configuration, and ingress controller selection.

03

Cluster Provisioning

EKS/GKE/AKS cluster deployment via Terraform (fully auditable, reproducible), RBAC configuration, network policies, Pod Security Standards, and node group auto-scaling.

04

Application Deployment

Helm charts or Kustomize for each application, HPA configuration, resource limits tuning, readiness/liveness probes, and GitOps deployment with ArgoCD.

05

Observability Setup

Prometheus + Grafana for cluster and application metrics, Loki for log aggregation, distributed tracing with OpenTelemetry and Jaeger, and alerting rules for critical cluster events.

06

Security Hardening

RBAC least-privilege policies, Network Policies for service isolation, Pod Security Admission, Trivy image scanning in CI, Falco runtime threat detection, and Secrets managed via Vault or AWS Secrets Manager.

Kubernetes FAQ

What is Kubernetes and why does my business need it?
Kubernetes is a container orchestration platform that automates deploying, scaling, and managing containerized applications. Businesses need it when they run multiple services that need independent scaling, zero-downtime deployments, and self-healing infrastructure. If you're running more than 3–5 services in containers, or you're experiencing deployment-induced downtime, Kubernetes is likely the right tool.
Should I use AWS EKS, Google GKE, or Azure AKS?
GKE (Google Kubernetes Engine) is the most mature managed Kubernetes service and offers Autopilot mode for near-zero ops overhead — ideal for teams that want to focus on applications. AWS EKS is best if you're already in the AWS ecosystem. Azure AKS is the natural choice for Microsoft-centric organizations. All three are production-grade; choice depends primarily on your existing cloud provider and team knowledge.
Can you migrate our existing Docker Compose setup to Kubernetes?
Yes, this is a common migration path. We convert docker-compose.yml files to Kubernetes manifests or Helm charts, add resource limits and probes, configure persistent storage, and set up ingress. The migration typically takes 5–15 business days depending on the number of services and their complexity.
How much does Kubernetes management cost?
Kubernetes cluster setup (design + provisioning + app migration + monitoring) starts from €1,500 as a project. Ongoing managed Kubernetes (upgrades, security patches, incident response, capacity planning) is available as part of our DevOps as a Service retainer from €2,500/month.
How do you handle Kubernetes cluster upgrades without downtime?
We follow a structured upgrade process: first upgrade the control plane (managed by EKS/GKE/AKS with zero downtime), then roll out node group upgrades using surge upgrades (add new nodes before removing old ones), with workloads protected by Pod Disruption Budgets. We test upgrades in staging first and monitor closely during the production upgrade window.
What is the difference between Kubernetes and Docker Swarm?
Docker Swarm is simpler to set up but lacks Kubernetes' advanced scheduling, RBAC, network policies, custom resources, and ecosystem integrations. Kubernetes has a steeper learning curve but is the de facto industry standard — 96% of containerized enterprises use it. For production workloads beyond basic setups, Kubernetes is the right choice and the one we recommend.
