What it is
vSphere Kubernetes Service, formerly vSphere with Tanzu, puts Kubernetes into the vSphere stack. Containers run on the platform that is already there and are managed with the same tools.
Why that is the point
Because the alternative is a second platform. Standing up a separate Kubernetes estate means a second operating model, second monitoring, second set of permissions, and a second team who know it at three in the morning. With vSphere skills the way in here is much shorter.
What it is for
Two cases, and the second gets overlooked.
Development teams need Kubernetes clusters to build and test containerised applications. That is the obvious one.
The other: organisations that write no software of their own still cannot avoid it, because third-party software increasingly ships only as a container image. The question stops being whether you run containers and becomes what you run them on.
What to watch
Kubernetes moves complexity, it does not remove it. Storage classes, networking and access rights want deciding before the first cluster exists, or the first use case decides them for every one after it.
