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.
The alternative: 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 in an emergency. With vSphere skills the way in here is much shorter.
What it is for
Two cases.
Development teams need Kubernetes clusters to build and test containerised applications.
The other: organisations that write no software of their own also need a platform for containers, because third-party software increasingly ships only as a container image.
What to watch
Storage classes, networking and access rights want deciding before the first cluster exists.
