Difference between Virtualization and Hypervisor

  • Last Updated : 23 Feb, 2021

1. Virtualization :
Virtualization, as name suggests, is a software that allows OS instances to run concurrently on single computer. Its type includes CPU virtualization, memory virtualization, device and I’O virtualization. It is applied in existing parts of system, so it always results in better efficiency and performance. It overall improves performance as due to technology that can balance resources.

2. Hypervisor :
Hypervisor, as name suggests, is a software, hardware, or firmware that generally make virtualization possible. It simply creates virtualization layers that separates CPU/processors, RAM and all other physical resources from virtual machines that we create. Its type includes Native hypervisor and Hosted hypervisor. It is used to allocate each VM resources such as CPU, memory, storage, and network to simply run guest OS and applications.

Difference between Virtualization and Hypervisor :



It uses software to create virtual version of something rather than actual one.It is software used to create and run virtual machines. 
It generally allows to use physical machines full capacity simply by distributing its capabilities among different users and environments.  It generally allows one host computer to support various guest virtual machines simply by sharing its resources virtually. 
Its main function is to manage workloads by transforming tradition computing radically simply to make it more scalable.  Its main function is to allocate system resources properly to each virtual machine that it manages.
It is most effective way to reduce IT expenses, boost efficiency, and agility for small to large size business.  It is most effective way to ensure that virtual machines are working effectively or not, smooth functioning of virtual machine, reduces costs of operations, etc. 
It is generally used for testing application on different platforms for OS, to conserver physical space, reduce cost, increase efficiency and productivity, etc.It is generally used for various tasks such as cloud computing, server management, running programs compatible with OS, etc.  
Its advantages include control independence and DevOps, enhance resiliency, reduce downtime, simplify data center management, etc. Its advantages include consolidating servers, desktop virtualization, data replication, etc.  
It is more cost-effective as compared to hypervisors. It is less cost-effective as compared to virtualization.
