Cloud & Kubernetes Engineering Hub

Welcome to vettom.pages.dev — a hands-on knowledge base, architectural blueprint collection, and reference guide covering Amazon EKS, Kubernetes, AWS, Containerization, SRE Observability, and DevOps automation.

  • Amazon EKS Auto Mode

    Explore AWS-managed compute, networking, and storage on EKS with built-in Karpenter autoscaling and API-based access control.

    Read Guide

  • Karpenter v1 Autoscaling

    Deploy fast, cost-efficient Kubernetes autoscaling with Karpenter v1, Spot instances, Bottlerocket/AL2023, and automated consolidation.

    Read Guide

  • Gateway API & Envoy Gateway

    Implement modern Layer 4/7 ingress using Envoy Gateway, AWS Network Load Balancer in IP mode, and client IP preservation.

    Read Guide

  • EKS Pod Identity & Security

    Map Kubernetes ServiceAccounts directly to AWS IAM roles with EKS Pod Identity — eliminating OIDC setup and simplifying multi-cluster management.
