I will design, deploy, and optimise a production-ready Kubernetes cluster on your cloud provider of choice — AWS (EKS), Google Cloud (GKE), or Azure (AKS). This service covers end-to-end cluster configuration including node group sizing and auto-scaling policies, namespace and RBAC design, network policy configuration, ingress controller setup (NGINX or ALB), certificate management with cert-manager, and integration with your existing cloud IAM and VPC/VNet. I will also review and optimise existing clusters for cost efficiency, resource utilisation, and security posture. Deliverables include working cluster configuration, Terraform or Helm chart code (where applicable), and clear documentation of the architecture and operational runbook.
