    Pros

    • Industry standard with a huge ecosystem of tools, operators and Helm charts
    • Runs the same way on every major cloud and on your own hardware
    • Self-healing, rolling updates and autoscaling built in

    Cons

    score / 100

    Cons

    • Linux only; no native Windows or macOS server
    • Still Kubernetes underneath, so the concepts and learning curve remain
    • Large production estates often need a fuller distribution or managed service

    61.8

    score / 100
