Customer Success Story

TQ Systems
At TQ-Systems, there was a need for a Kubernetes environment. Their developers had already built a vanilla Kubernetes cluster in a test environment and recognized its complexity in deployment and day-2 management. vSphere is used in combination with Tanzu. In this way, a Tanzu Kubernetes cluster is made available quickly, easily and in a controlled manner. With Tanzu Mission Control, a central cloud-based control layer is used to centrally manage each Kubernetes cluster.
