Hyper V vs VMware : Detailed Comparison
Hyper V vs VMware
In computing, virtualization refers to the act of engendering a virtual version of one thing, as well as virtual constituent platforms, storage contrivances, and electronic network resources. On a very broad level, there are 3 styles of Server Virtualization –
- Full virtualization
- OS-level virtualization.
A hypervisor, conjointly referred to as a virtual machine monitor, is a method that makes and runs virtual machines (VMs). A hypervisor permits one host laptop to support multiple guest VMs by nearly sharing its resources, like memory and process.
Generally, there are a unit 2 kinds of hypervisors. Type-1 hypervisors, which is also known as “bare metal,” runs directly on the host’s hardware. Type-2 hypervisors, also known as “hosted,” run as a package layer, like alternative laptop programs.
What is Hyper V?
Hyper-V functions by running each VM in their respective isolated space, while leveraging the same hardware. Each Virtual Machine in this scenario may have their own Operating system independent of other VMs. Infact, such logical partitioning by virtualization helps keep the issues like crashing etc local to the VM while other workloads can run independently.

What Is VMware?
VMware is a company that provides platform for virtualization. Vmware was launched in year 1998 in Palo Alto, California. The first virtualization software was VMware Workstation. In year 2001, VMWare GSX Server and VMWare ESX server were introduced in the market. It is notable that majority of the VMware virtualization software programs are for business use.
VMware vSphere is a server virtualization platform created by VMware. Basically, vSphere encompasses a collection of virtualization products that hold the ESXi hypervisor, vSphere shopper, VMware digital computer, vCenter, and others.
Editions of VMware are:
- VMware vSphere Standard
- VMware vSphere Enterprise Plus
- VMware vSphere Operations Management Enterprise Plus
- VMware vSphere Platinum

Some PROS and CONS of Hyper V:
PROS OF HYPER V
CONS OF HYPER V
|Minimal device driver management.||A crash of the primary OS will crash all VMs.|
|A wide range of compatible devices.||OS must be installed in order for the Hypervisor Layer to operate.|
|New server roles are easy to install.||Frequent OS and security updates translate into more overhead.|
|High resilience to corrupt external code.||Lack of support for service templates.|
|Shorter initialization time.|
|Zero downtime to perform maintenance or apply security updates.|
|Readily scalable services.|
Some PROS and CONS of VMware:
PROS OF VMware
CONS OF VMware
|No OS is required for controlling the management components.||Vendor support unavailable in issue with Incompatibility of hardware.|
|No additional patch required for Controlling Layer components.||Trial software missing some functionality.|
|Vendor support is good.||Steep learning curve.|
|Out-of-the-box governance feature set.||Complex device drivers will slow the initialization time.|
|Available AWS applications.||Corrupt external code may slow initialization or hang a server.|
Hyper V and VMware are both extremely powerful hypervisors on which you can run your enterprise data center production workloads. Each have various characteristics that make them unique. Each of these characteristics serve the basis on which many make the decision to go with one hypervisor or another for running their enterprise data centres.
