Re-Imagining Virtualization with Kubernetes and KubeVirt – Part II

Re-Imagining Virtualization with Kubernetes and KubeVirt - Part II

KubeVirt – Traditional Virtualization with the New Kubernetes Previously, in Part I of this blog series, we introduced the idea that KubeVirt is about balance: Mature virtualization features and concepts, yet Kubernetes philosophy and semantics. Pods and containers disappear when stopped. Virtual machines have a life cycle and their configurations persist so they can be […]

Controlling Namespace Configurations

In the Kubernetes namespace model, the high-level idea is that a development team is given access to a namespace. Within the confines of that sandbox, they have the freedom to perform any action they desire. There are, however, a set of namespaced objects whose ownership is not so immediately clear. For example, while it’s obvious […]

As with any new technology there can be the temptation to “move everything to containers”, yet history shows the length of such transitions is measured in years, or even decades. With a major part of the current application […]
