在您的数据中心中运行Kubernetes集群的位置在哪里？在裸金属上，您可以避免虚拟化层的开销和成本。然而，由于容器的共享内核特性以及Kubernetes缺乏内置的多租户功能，共享裸金属Kubernetes集群以最大化硬件利用可能既不安全也不方便。另一方面，虚拟化长期以来广泛采用，用于在多个工作负载之间共享裸金属主机并保持安全隔离。但是，商业虚拟化产品的总拥有成本可能令人生畏，其功能集可能过于庞大，甚至对于像Kubernetes集群这样的现代分布式工作负载来说可能是负担。通过使用云超级虚拟机（Cloud Hypervisor VMs）使Kubernetes能够在现代云工作负载中专门设计的轻量级虚拟化程序，Virtink使得主机Kubernetes集群能够以安全、轻量级和高效的方式托管客户Kubernetes集群。

Where to run Kubernetes clusters in your data center? On bare-metals, you avoid both the overhead and costs of a virtualization layer. However, due to shared-kernel nature of containers and lacking of built-in multi-tenant features in Kubernetes, it can be both unsafe and inconvenient to share bare-metal Kubernetes cluster across multiple users to maximize hardware utilizations. On the other hand, virtualization has been long adopted widely for sharing bare-metal host between multiple workloads while keeping them safely isolated. But the total cost of ownership for a commercial virtualization product can be daunting, and its feature set can be an overkill or even a burden for modern distributed workloads like Kubernetes clusters. By enabling Kubernetes with Cloud Hypervisor VMs, a lightweight hypervisor designed specifically for modern cloud workloads, Virtink makes a host Kubernetes cluster possible to host guest Kubernetes clusters in a safe, lightweight and efficient way.
