This article introduces the knowledge of "what is a virtual machine in the Kubernetes world". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

People participating in KubeCon know that container technology will continue to exist. In fact, "Gartner predicts that more than 75 per cent of global organizations will run containerized applications in production by 2022, a significant increase from less than 30 per cent in 2019". Submit applications in a timely manner to keep us competitive and relevant to our customer base. To do this, many companies have adopted container frameworks to improve efficiency and speed. Adapting to new technologies is not always easy. Some applications may need to use legacy technologies, or may need to invest a lot of time and effort to build new technologies. How do we deal with applications that need to use virtual machines without complicating the management of virtualization and container technologies? Welcome to KubeVirt.

The KubeVirt project reimagines virtual machines in the Kubernetes world. Virtual machines can be created or migrated from legacy frameworks to kubernetes-first management paradigms. Developers can use their existing Kubernetes toolset to natively manage VM or convert these workloads into containers. This provides space for organizing and supporting development teams to update applications on real-world timelines that make sense to their business.

Does that sound like fun? Maybe it's a little too amazing? Here are some ways to start experimenting with virtual machines in Kubernetes.

Support legacy architecture from a single control plane

The beauty of KubeVirt is that it allows development teams to redesign existing applications as cloud-native, container-first deployments, rather than placing developers with the burden of rebuilding everything on the Kubernetes with an impossible timeline. Simplifies the management of VM and containers through a single control plane in KubeVirt. Based on award-winning KVM technology, KubeVirt provides mature virtualization capabilities and performance, and directly brings the benefits of Kubernetes.

Application modernization

There are three key considerations when trying to implement an DevOps or cloud native application architecture: business requirements, technical requirements, and migration strategies.

Business requirements: modernize workloads that can benefit from Kubernetes capabilities while maintaining more traditional features on virtual machines. Use this opportunity to determine your business needs for the next 3-5 years and to understand what you are going to do today. Do you all use virtual machines? Are you interested in DevOps or Yunyuan? If you are interested in Kubernetes but know that there are dependencies on the virtual machine, you can include KubeVirt as a test option in the conversion process.

Technical considerations: when you know that Kubernetes will appear in your future, please consider the technical capabilities of KubeVirt. Kubernetes provides a management example that is different from traditional virtual machines. The strategies for resizing, backup, and even workload authentication may be different from what you are experiencing right now. One of the main advantages of KubeVirt is that it simplifies the number of management toolsets by placing virtual machines and containers under a single control plane. KubeVirt is a dynamic project-if the platform doesn't meet your needs 100% today, don't give it up.

Migration strategy: workloads, including file and web servers, .NET applications, Java, and enterprise databases, are ideal for migrating from traditional VM to Kubernetes. Starting with such a VM, you can experiment with the simplest settings before moving to more complex workloads. Here, you can import the virtual machine into KubeVirt and use best practices for VM mirroring or Windows installation.

Develop at one's own pace

It is easy to start using VM in Kubernetes (KubeVirt can be downloaded and deployed as an operator), and it is simple and effective to develop. If you are going to use KubeVirt, you can start a new virtual machine or migrate the existing VM to KubeVirt. Extending the cluster is as simple as adding a node and is executed entirely through the operator. There is no limit to the number of virtual machines supported, and virtual machines have the same data persistence that is common in traditional virtual machine environments. As you become more familiar with the platform, you can scale up and enhance VM and eventually replace traditional virtualization.

KubeVirt is used and deployed on a large scale by customers and community members around the world. OpenShift Virtualization is now a fully supported feature of the Red Hat OpenShift container platform. OpenShift Virtualization is the first fully supported product based on KubeVirt, eliminating the silo between operation and development that often exists in traditional application stacks.
