By decoupling software from physical servers, teams can run multiple workloads on a single machine, speed up provisioning, and improve reliability. This approach is common in data centers and also in public and private clouds today. Hypervisors are the engines behind virtualization. They come in two main flavors: Type 1, which runs directly on hardware, and Type 2, which runs on an operating system. Type 1 examples include VMware ESXi, Microsoft Hyper-V, and KVM.
