Difference between Virtualization and Emulation
  • Last Updated : 22 Feb, 2021

1. Virtualization :
Virtualization, as name suggests, is a technique that is used for having access to computing resources and devices in completely function manner no matter what is their physical layout or location. It provides virtual environment simply for running virtual windowsXP machine. It simply manages workloads by transforming traditional computing radically to increase scalability. It also improves operating effectiveness and provide greater workload mobility.

2. Emulation :
Emulation, as name suggests, is a technique in which Virtual machines simulates complete hardware in software. There are many virtualization techniques that were developed in or inherited from emulation technique. It is very useful when designing software for various systems. It simply allows us to use current platform to access an older application, data, or operating system.

Difference between Virtualization and Emulation :

Virtualization 

Emulation  

It is a process of creating virtual version of something such as OS, server, storage device, etc.  It is a process of simulating another kind of device.  
It generally increases IT agility, increase scalability, improve flexibility, saves costs, etc.  It generally increases customer satisfaction, install acceleration at customer site that minimizes impact on production, increase confidence, etc.  
It simply allows and help us to use full capacity of physical machines by distributing its capabilities among different environments or users.  It simply allows and help us to run software from totally different device on our computer.  
Its main aim is to centralize administrative tasks that in turn improves scalability and workloads.Its main aim is to allow subsystem to present same interface and characteristics as another.  
It runs code directly with different set of domains in use language.  It’s uses interpreter that translate and convert source code into readable format of host system so that it can be processed further.  
It creates an isolated environment.It reproduces behavior of same hardware including quirks, bugs, etc.  
It usually accesses hardware directly without any need of software bridge.  It usually requires software bridge to access hardware. 
It is less cost-effective I.e., costlier as compared emulation.  It is more cost-effective as compared to virtualization.  
It provides effective and better backup solutions as compared to emulation. It provides less effective backup solution as compared to virtualization.  
It makes use of and rely on CPU.  It does not use CPU.  
It is normally faster than emulation.  It is unnecessarily slower than virtualization.
