On July 11, the KubeVirt community officially announced the release of KubeVirt v1.0. As a fully matured Virtual Machine Management solution for Kubernetes, KubeVirt provides VM users another option to modernize IT infrastructure: in conjunction with Kubernetes persistent storage, users can conveniently run both VMs and containers on top of Kubernetes with no need to worry about the stability and performance of Kubernetes clusters.

As a leading enterprise-grade Kubernetes-native distributed storage, IOMesh can enhance VMs and containers in KubeVirt with outstanding performance and high availability. In the following sections, we will dive into key capabilities of Kubernetes storage in supporting KubeVirt, and explore how IOMesh performs through a case study. 

Gartner: Convergence of VM and Container Management is Dominating Kubernetes Deployment

Cloud-native technologies accelerate the modernization progress of IT infrastructure, and yet introduce new management challenges. One such challenge is how to combine existing virtualized workloads with new container workloads on one platform and achieve unified management of both. To address this issue, projects focusing on the convergence of VM and container management have emerged. 

Currently, there are two basic routes to converge VM and container management:

Coexist (Left) Vs. Container-Centric (Right)

As a container-centric solution, KubeVirt enables users to centralize the management of containers and VMs through the Kubernetes API. This reduces complexity in operations and maintenance (O&M) since administrators only need to familiarize themselves with Kubernetes operations. Moreover, unlike traditional virtualization that depends on vendors’ proprietary APIs, KubeVirt seamlessly integrates with Kubernetes through Kubernetes API. This close integration allows users to effortlessly tap into the rich ecosystem of Kubernetes and use its wide range of tools for monitoring, logging, networking, storage, etc. 

This is why Gartner highlights in Market Guide for Container Management that compared to using bare-metal servers, more users are turning to solutions that converge VM and container management; with a unified platform, users can enjoy advantages of both IT architectures and undertake IT transformation at their preferred pace.

How to Select KubeVirt-Friendly Storage?

To fully leverage KubeVirt’s potential in central management, it is essential to have underlying storage that can provide high performance for both containers and VMs. Therefore, block storage can be a better choice. Moreover, the storage solution should be KubeVirt-friendly, meaning that it can provide advanced features for VMs in KubeVirt. 

IOMesh: Reliable and Performant Distributed Storage for Containers and VMs in KubeVirt

IOMesh is an enterprise Kubernetes-native distributed storage solution. Leveraging Kubernetes native operation and tools, IOMesh can be fully integrated into the Kubernetes ecosystem, providing production-ready storage services to containers and VMs in KubeVirt through converged deployment.

Case Study

A video technological research company is developing offline video rendering services, with core applications running on VMs (Windows + Linux) and containers in KubeVirt.

Since these applications have high requirements for storage performance and availability, the user has evaluated and tested multiple cloud-native storage solutions. Yet, none of these solutions could meet their expectations. The user’s key requirements are listed below:

To find the right storage solution, the user tried out more options and conducted a performance test on IOMesh. The results were impressive: In the simulated production environment, IOMesh demonstrated outstanding single-node random read/write IOPS, achieving 130K+ and 45K+ respectively, while the sequential read/write bandwidth exceeded 1.6GiB/s+. Additionally, IOMesh’s extensive advanced features contributed to the enhanced availability of Kubernetes clusters.
