What is a Hypervisor

What is a Hypervisor and Which Type Fits Your Business Module?

Essentially, a hypervisor is a machine manager which has the capacity of creating and running virtual machines. This is a process which separates a computers operating system from different physical hardware, this machine manager is the underlining concept behind virtualization.

A hypervisor will empower businesses with the unique ability to run multiple virtual machines on a single physical host. This will instantly maximize the efficiency of the main physical host as it enhances various functions such as memory, CPU cycles, cyber security and network bandwidth.

Background of Hypervisors

Previously this was only possible on main frame computers which were designed by IBM, they had focused on virtualization way before any other manufacturer in the market. IBM’s main frame computer was brilliantly engineered to allow programmers to develop virtual functions without affecting the stability and efficiency of the main system. Furthermore, these devices were way ahead of their time as IBM was already focusing on the concept of virtualization without the deployment of expensive development systems.

However, hypervisors gained exponential popularity after the inception of Unix and Linux operating systems. These systems were built to allow virtualization and fueled the growth of hypervisors as businesses started to understand the true potential of this process. Generally speaking, this process is allowing a single unit to perform simultaneous functions without compromising on the efficiency of the host unit. This consolidation of servers has paved the way for virtualization and businesses all around the world are integrating their modules to reap the vast benefits of hypervisors.

However, before you invest in this network upgrade, it is imperative that you understand which type best suits your commercial entities specifications. To make sure that you make an informed decision, we have articulated a guide on the different types of hypervisors. This list is as follows,

Hypervisor Type 1

These systems run directly on the physical hardware and are also known as bare metal embedded hypervisor. Some of the most profound versions are mentioned below.

VMware ESX and ESXI: This type of hypervisor offers the highest level of scalability and functionality; however, you will need a license to operate this system which will increase your operational costs. You can find cost effective bundles for small businesses but these do not offer the same level of scalability.

Furthermore, there are many different versions available in the market and each of them is unique in their own perspective. VMware is currently the most popular system in the market, they offer free editions and various commercial editions as well.

Microsoft Hyper-V: Microsoft’s hypervisor does not provide the same level of scalability or performance, that VMware provides. However, this product is highly demanded all around the world as the cSphere, Xenserver and hyper-V have found their way in almost every business type.  

Currently there is only one free edition offered but this does not include GUI or any virtualization rights. The commercial versions have recently been enhanced after the development of the latest Windows server and can easily integrate with any network.

Oracle VM: The Oracle VM is derived from the open source Xen. Although this system is being offered for free, all of the upgrades are quite expensive. Additionally, the Oracle VM has limited functions and is mostly used by small businesses with restricted digital architecture.

Citrix XenServer: This server is completely free of cost as it was developed as an open source project. The Citrix Xenserver is offered in four different commercial editions and each of them utilizes Xen as the main commercial server.

Hypervisor type 2

This type of hypervisor is run on a host server which will also provide a variety of different services. Due to the rapid digital transformation of today’s market eco-system, most business choose type 2 Hypervisor to increase network transparency.

Red Hat Enterprise Virtualization:  This type of hypervisor has the capacity of transforming Linux kernel into hypervisor. This allows the network to have seamless access to the main physical unit and provides both types of hypervisors.

KVM: Another popular type 2 of hypervisor is the KVM as this provides a virtual infrastructure which includes a plethora of different extension facilities.

VMware server: This is another free version of hypervisor and it has been present in the market for over a decade now. This server is quite efficient in terms of seamless integration but it has not been updated for a very long time now.

VMware server: This is the most advanced edition in the market today and it is being used by all of the power house companies in the world. The VMware server is ideal for sandbox environments and if you want to operate different systems on a single desktop.

Of course truly understanding the applications and versatility of each hypervisor will require a high degree of knowledge in computer sciences. However, anyone can clearly understand the true potential of these systems and the vast benefits that they provide. To enunciate why investing in a hypervisor is a viable investment, here is a list of the top benefits of Hypervisors.

  • Immediate reduction in the requirement of hardware
  • Provides airtight security
  • Boosts efficiency by a substantial margin
  • Impeccable network, if one software fails, the rest will not be affected
  • Eases the process of upgrading a system to new hardware
  • Immediate reduction in costs
  • Does not require a high level of maintenance
  • Will help optimize your business module


So which type of hypervisor best suits your business?

By now you should have a thorough understanding about the different types of hypervisors and the popular versions available in the market. As a business owner you will first have to determine how many functions will you integrate to a single unit, you will clearly have to define what functions are required for your business. A host server will solve many integration issues and will instantly provide your business with powerful digital tools while a type 2 would be more cost effective. Keep your functional requirements and budget in mind, to determine which type best suits your business.
