What is the difference between Virtualization & Cloud?

By bryanwaltersmn ·
Tags: Cloud
While reviewing some technology blogs have landed up on a discussion where a technology expert said that many hosting providers fake about their services and they offer virtualization options to existing hosting packages and call it as Cloud. which create the misconception about Cloud.

I would really like to know what are the key factors that differentiate Virtualization from Cloud technology?

What is the difference between Virtualization & Cloud?

by liyagrey In reply to What is the difference be ...

Virtualization is a simple process in which software is used to simulate hardware. It can exist without the cloud. But cloud computing cannot exist without virtualization. Cloud computing allows businesses to store and access applications and data on virtual servers, rather than in a physical machine.

Thank you.

Your explanation on cloud and virtualization sounds much easier and acceptable.

I stumbled upon this a while ago..it might help you understand

The term virtualization refers to a process used to create a virtual environment.

Virtualization allows a user to run multiple operating systems on one computer simultaneously. It is like getting multiple servers for each physical server you buy.
It is creation of virtual (rather than actual) version of something such as an operating system, a desktop, a server or network resources, etc.
The technology behind virtualization is known as virtual machine monitor (VMM) or virtual manager. Virtualization is also known as the backbone of cloud computing.


The term cloud computing has become a buzzword in the tech industry, which refers to automated control, built on top of a virtualized infrastructure consisting of storage, compute and network components.

Cloud computing gives your company access to complex applications and computing resources via the Internet.
Virtualization manipulates hardware and cloud computing manipulates the result.
It is the delivery of shared computing resources, software or data as a service (SaaS) on-demand through the Internet.

Short description and difference

by DarwinJones In reply to I stumbled upon this a wh ...

Virtualization, refers to a software that separates physical infrastructures to create various dedicated resources. It powers cloud computing.

cloud or cloud computing, refers to the hosted services over the internet that is being delivered.

virtualization is software that manipulates hardware, while cloud computing refers to a service that results from that manipulation. Here’s an article that discusses this question and provides examples and detailed explanation

virtuallzation and cloud

Cloud computing is the delivery of shared computing resources, software or data — as a service and on-demand through the Internet." Most of the confusion occurs because visualization and cloud computing work together to provide different types of services, as is the case with private clouds

Virtualization Vs Cloud

by jessenickol In reply to What is the difference be ...

There are two ways to answer this - one about the concept and the technology and second about the way these technologies are being used in the real world to solve similar problems.

1. The technologies at a high level

Virtualization is about taking a physical device and breaking it down into smaller pieces that can be provisioned, shared, moved, etc. thus making resources more efficient and more dynamic.

Cloud is about making IT resources (virtualized usually) available on-demand, with a pay-as-you-go, model, accessible via an API (a software program can access, create, configure, etc. virtual resources)


2. About how they are used to solve IT problems

While similar in the technology they use (most cloud solutions rely heavily on virtualization technology), they are two solutions to two different problems

Virtualization is about resource optimization. Large IT departments had hundreds of applications running on old hardware, so they had to manage hundreds of old servers too. Virtualization served like an app Tetris, where multiple applications, sometimes hundreds, could run on one physical server. This resulted in a dramatic reduction in the number of physical servers that have to be managed, resulting in performance, cost, and energy consumption savings plus time and effort saved by keeping these old servers running.

Virtualization has evolved since, allowing replication of virtual machines, moving machines across servers, etc. however, the fundamental concept is still the same: administrators move apps between servers in this Tetris game.

With the cloud, infrastructure is completely transparent. A cloud creates a pool of IT resources (compute power, storage, networking, etc.) and makes it available to customers on demand. A user requests resources that are provisioned immediately and the user has no concept of the underlying hardware other than what is the capacity allocated to him or her.

The real power of cloud comes from the automation made possible by creating applications that are smart enough to control the infrastructure resources they need via an API.

With virtualization, an application that needs scaling usually gets a bigger Tetris brick: the virtual server gets larger (but is still limited to the total physical server capacity).

With cloud, an application can scale vertically by resizing the server to a larger one, but it can also scale horizontally - creating more servers in a cluster as the application requires, across
