The Kubernetes platform’s evolution allows organizations to revisit how they develop new applications using microservices and containers. 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 landscape residing in virtual machines, the mission of the open source KubeVirt project is to re-imagine virtualization in a Kubernetes world – enabling the use of Kubernetes as a converged platform for running and managing both application containers and virtual machines side by side.
The beauty and simplicity of KVM virtualization is that virtual machines are Linux processes, benefiting from existing Linux features. Virtualization is mostly used in managed environments, orchestrating virtual machines (compute) across a cluster of hosts, network and storage. Kubernetes is orchestrating containers (processes) across a cluster of hosts, network and storage.
With KVM virtual machine being a Linux process, why not use Kubernetes to orchestrate virtual machines?
