    Kubernetes reviews

    Kubernetes automates the deployment, scaling and self-healing of containerized applications, with costs coming from the infrastructure that runs it.

    Kubernetes carries no license cost; the decision point is whether the team can absorb the compute and management fees of a managed Kubernetes offering, or the time cost of self-hosting.

    About

    In practice. What you can do with Kubernetes.

    Kubernetes orchestrates containerized applications: it schedules them across machines, restarts and replaces failed containers, handles rolling updates and rollbacks, and manages service discovery and load balancing through declarative YAML manifests.

    It is free and open source under Apache 2.0, so the real budget line is the compute, storage and managed control-plane fees charged by whichever cloud provider or self-hosted infrastructure runs it. It fits a developer or small technical team that already needs to run containers at scale, not someone looking for the simplest way to put an app online.

    Practical uses

    • ScalingAutomatically add and remove application instances as traffic changes, without manual server management.
    • ResilienceRestart and reschedule failed containers automatically to keep a service available during incidents.

    Features & use cases

    Devops

    Pros and cons. What Kubernetes does well, and what to expect.

    Pros

    • No license fee: the software itself is free and open source.
    • Self-healing and rolling updates reduce manual intervention once a cluster is running.

    Cons

    • Steep learning curve and real operational complexity to run and maintain.
    • Requires ongoing cluster operations (upgrades, security patching, networking) unless fully managed.

    When it makes sense. Keep Kubernetes, or challenge it?

    Keep if

    • A developer or technical team already needs to run and scale multiple containerized services and has the skills (or budget for a managed service) to operate a cluster.

    Challenge if

    • A single application needs to go online without dedicated operational time, where a simpler managed deploy platform fits better.

    Our verdict. What to know about Kubernetes.

    Why this verdict

    Average

    Added value

    Kubernetes itself has no license fee, but the real cost is the compute, storage and managed control-plane fees of the infrastructure running it, so the value only pays off once an application genuinely needs orchestration at scale.

    Simplicity

    The documentation itself describes a steep learning curve and significant operational complexity compared to simpler deployment platforms, plus ongoing cluster operations unless using a fully managed offering.

    Fit for purpose

    Delivers what it announces: automated deployment, self-healing restarts, rolling updates/rollbacks, service discovery and load balancing through declarative manifests.

    Performance

    Covers the full orchestration stack (deployment, self-healing, rolling updates, service discovery, load balancing) rather than a subset of it.

    Reversibility

    Neutral score: export and portability of workloads leaving a given Kubernetes setup are not covered by the collected sources.
