Server Virtualization

Bare Metal to Fully Virtualized

More than 85% of all workloads will be processed by cloud data centers in the coming years, up from less than 20% in 2018. This trend of virtualization and cloud computing shows that, more and more organizations are shifting towards virtualization to take advantage of the benefits it provides.

What is Virtualization?

Virtualization takes advantage of something called a Hypervisor. This Hypervisor can partition a server into multiple virtual servers. This is known as “Hypervisor Virtualization.”

Hypervisor virtualization is a technology that allows multiple virtual machines (VMs) to share a single physical host. Here are 10 facts you should know about hypervisor virtualization:

  1. Hypervisor virtualization is also known as hardware virtualization or Type-1 virtualization.
  2. Hypervisors are software programs that create and run virtual machines. They are also responsible for managing the resources of the physical host, such as CPU, memory, and storage.
  3. Hypervisors can run on top of the host operating system or directly on the host’s hardware.
  4. Hypervisors are categorized into two types: Type 1, also known as native or bare-metal hypervisors, runs directly on the host’s hardware and provides a high level of performance and security. Type 2, also known as hosted hypervisors, runs on top of a host operating system and provides lower performance and security.
  5. Hypervisors are used for a variety of purposes, such as server consolidation, cloud computing, and disaster recovery.
  6. Hypervisors can support multiple operating systems on the same physical host, which allows for greater flexibility and cost savings.
  7. Hypervisors can also provide advanced features such as network virtualization, storage virtualization, and live migration of virtual machines.
  8. Some popular hypervisors include VMware vSphere, Microsoft Hyper-V, Citrix Hypervisor, and Oracle VM VirtualBox.
  9. Hypervisor virtualization also has security concerns, as a single vulnerability in the hypervisor can potentially compromise all the virtual machines running on it.
  10. Hypervisor virtualization can also have a performance impact on the virtual machines, due to the overhead associated with running on top of the host, this is why it’s important to choose the right hypervisor that can perform well and handle the load of the virtualized infrastructure.
