What are the differences between RHEV and VMware vSphere?

Hi Sridhar,    This is Rajkumar Gera, VP IT  in one of the Telecom. Below are some of the points, may help you: 

Here is a comparison of the two hypervisors, RHEV (Red Hat Enterprise Virtualization) and VMware vSphere:

RHEV

Pros:

• Open source


• Highly scalable


• Cost-effective

Cons:

• Not as mature as VMware vSphere


• Not as widely supported as VMware vSphere

VMware vSphere

Pros:

• Mature and widely supported


• Wide range of features


• Easy to use and manage

Cons:

• Not open source


• Can be expensive

Some prefer RHEV because it is open-source and cost-effective. However, VMware vSphere may be the better option if you need a hypervisor with a wide range of features and support.

As to which solution consumes fewer resources, RHEV is a lighter-weight hypervisor than VMware vSphere, so it consumes fewer resources. However, you must remember that each hypervisor's resource consumption depends on the configuration and workload.
