This can leave your organization with outdated technology and insufficient support, hindering your ability to stay competitive.
  • Vendor lock-in: Increased dependency on traditional hypervisor solutions can severely limit your flexibility. This dependency can make future transitions to alternative solutions more challenging and costly, constraining your organization’s ability to adapt to new technologies and market demands.
  • Operational complexity: Having separate environments for VMs and containers adds to the management complexity during application modernization compared to a Kubernetes-native solution that can run containers and VMs on the same platform.
  • Security and compliance: Traditional type-1 hypervisors, while still current, can present security vulnerabilities and compliance challenges due to their complex architecture. KubeVirt’s modern, streamlined architecture offers significant security and compliance advantages. It enhances the security posture of your virtual machine infrastructure and simplifies the process of maintaining regulatory compliance. However, it’s important to note that while KubeVirt fortifies the underlying infrastructure, the security of the applications running on these VMs remains the organization’s responsibility. By transitioning to KubeVirt, you ensure a more secure and compliant foundation, reducing the risk of breaches and easing regulatory adherence.
  • Economic pressure: In the current economic climate, optimizing costs and improving efficiency are critical. The cost savings from moving to KubeVirt can provide a significant financial advantage.

For executive decision-makers, there is real urgency to move from traditional type-1 hypervisor technologies to KubeVirt within a Kubernetes environment. With the current market dynamics in the space and the fact that the future of applications has shifted to cloud-native microservices, this transition needs to happen. The transition enhances operational efficiency and reduces costs and positions the organization for future growth and innovation. Embracing KubeVirt is a strategic move that aligns with goals around modernizing and prepares the organization to meet the challenges and opportunities of the modern digital landscape.


We must also consider the risks that come with adoption. While Diamanti alleviates many challenges, organizations with limited internal expertise in managing advanced Kubernetes environments might face adoption hurdles. The intricate nature of container orchestration and persistent storage integration demands a certain level of technical acumen, which could pose a barrier to less mature IT teams. Among the concerns in a transition to KubeVirt-based VMs:

  • Disruption during transition: Migrating from well-established hypervisors to KubeVirt will be a training opportunity for your IT teams in operations. However, the migration tools will have a familiar operating environment to those you have likely used in the past. We recommend testing in a POC environment before going live.
  • Learning curve: IT teams may face a steep learning curve; however, those lessons learned from your DevOps teams can be leveraged to speed up the learning curve, and having a single platform for all your applications is a benefit worth investing in.
  • Compatibility issues: Since this is a virtual machine environment, compatibility issues are expected to be minor; however, check with your vendor support teams to see if there are any changes to support. We also recommend prioritizing those applications that support KubeVirt.
  • Storage integration: Integrating persistent storage in a Kubernetes environment must be considered and carefully planned for data consistency, availability, and performance.
  • Security management: KubeVirt introduces additional layers beyond native Kubernetes that need to be secured, such as the VM layer on top of containers. This will result in a single platform to secure and govern, where before you had at least two. Short-term risk for long-term benefit.
