Virtualization and Cloud Computing-These two words are liable to be confused as they are very similar in nature but not the same. Many people feel that the two are the same and it is not a difficult task to understand the difference between virtualization and cloud computing. As said by an IT company, “Cloud computing and virtualization are two approaches to computing that attempt to make more efficient use of computer hardware”. Here, in this Article, we are going to discuss “What is the difference between Virtualization and Cloud Computing?
Virtualization allows businesses to use a single piece of physical hardware to perform the work of a large number of machines. Multiple instances of an operating system running on a single hardware device are much more cost-effective than a piece of hardware for each server task.
Today, these are two major products on the market that offer powerful, free, paid or embedded solutions in the Windows Server 2008 R2 Operating System or Server 2012.
IT data is growing exponentially. Organizations are increasingly depending on IT processes to increase productivity and competitiveness. Hence. the possible decrease in IT infrastructure management costs is a top business priority.
In recent years, several ways have emerged to address this cost reduction, including virtualization and cloud computing. Virtualization and Cloud Computing are two different but complementary concepts. This article will focus on presenting you the definitions of these two terms, as well as their advantages and possible uses for companies.
What is Virtualization and Cloud Computing?
What is Virtualization?
There are many types of virtualization, such as client virtualization or supercomputer virtualization. The most popular form of virtualization is server virtualization. Thus, virtualization helps in dematerializing the behavior and data of a server or a machine to run several of these dematerialized instances on the same physical server. In this way, the different instances created to share the resources of the physical server. But beyond this sharing, virtualization requires the respect of several principles:
- An exact partitioning: each instance or operating system must operate totally dependent and without interfering with other bodies.
- A transparent operation: being virtualized should in no way change the behavior of the operating system or applications
- Compatibility between all applications in a virtualized instance
What are the Benefits with Virtualization?
The benefits with virtualization are obvious:
it is possible to reduce costs, both in terms of investment and operating costs on a daily basis (electricity, cooling, operation, etc) This is possible by sharing resources, and by avoiding the need to multiply the buying of physical servers. This is more interesting, that a server is generally used well below its capacity.
In addition, by managing multiple instances virtually, it is possible to greatly facilitate the daily administration of servers and to arrange and distribute them much faster than it would be possible with physical resources. For example, setting up a new server, mounting a test server, or setting up a new server in case of an incident is easier and faster.
Virtualization is no more dangerous in terms of security. It would even tend to be the opposite. Physical server security that encompasses all virtualized instances is critical. By centralizing data and hosting locations for applications and reducing the number of components, security management becomes easier to implement, work and to maintain.
Types of Virtualization in the Cloud Computing
- Network Virtualization
- Hardware Virtualization
- Memory Virtualization
- Desktop Virtualization
- Software Virtualization
- Data Virtualization
- Storage Virtualization
Virtualization and Cloud computing
While virtualization and cloud computing are not the same, they are however based on common fundamentals. As of today, the delivery of cloud computing services almost certainly involves virtualization. Because Cloud is the delivery of services available in an index. The Cloud works by combining multiple resources, which will be servers, storage locations, databases or even firewall for example.
Thus, if virtualization is necessary, it is the automation of the provision of these resources, as well as the monitoring of their consumption for billing purposes, which is truly called the cloud.
The Benefits with the Cloud Computing
In addition to virtualization technology, the benefit of the cloud is the ability of customers to manage these virtual instances simply, quickly, dynamically, and lively. The services thus implemented must be immediately available and usable for the clients without the need for a system administrator.
Thus, one could say that the advantage of cloud computing, compared to virtualization, is to make possible for the customer a real coordination of resources, usable and billable as a service. But the cloud also benefits from all the advantages of virtualization, since the latter is one of its components. Cloud benefits also from cost reduction, the liveliness offered by the implementation and the reduction of the energy bill.
Avoid Risks with the Cloud Computing
- Choose the right Cloud Service
- Better to keep multiple copies of Data
- It is always good to secure your data
- Do not use cloud services if you do not know why you are using the cloud
Cloud or virtualization – What should we choose?
Since virtualization is a component of the cloud, of course, it is not a question of choosing. Both maximize IT resources and therefore reduce costs and increase liveliness. But the cloud and virtualization are not synonymous: while virtualization is a technology to simulate multiple virtual instances within the same physical hardware, cloud computing makes it easy to coordinate the management of these instances virtual and transform the delivery of these resources in a service billable consumption.
Cloud Computing – The Future of Technology
The user can use virtualization without the Cloud and the Cloud without Virtualization. In general, these two are combined, but they need not be like that always. The cloud technology is going to emerge as the future of technology.
Virtualization is therefore not the heart of the cloud concept but given by the current technological advancements in IT infrastructure management, it is now an integral part of its operation. It is in this sense that we must understand the relationship between these two concepts
