Relationship Between Cloud Computing and Virtualization
Cloud Computing is a technology of some companies that want to reduce costs, and access to the programs and applications that are not installed physically in the Computer or Server. The concept of power-perhaps in comparison to how this technology works, although the consumer, know where and how the electricity is produced, consumers still have the power, if you need only to connect to a device and activate it. This concept is almost the same as cloud computing, but the most important type of communication is with this technology the internet. The cloud computing by NIST or National Institute of Standards and Technology the technology is defined, that provides scalable IT capabilities that offers services via the internet to various users, many users share pooled resources, reducing costs and the resulting computing efficiency.
Think of it this way, a company computer, you must deploy various systems and services, transmission and storage of the information, the means also, the more computers you have, the more software licenses, servers and storage devices would be necessary, as your business grows. Behind all this there are several people working throughout the day to ensure that the servers, applications and storage to work properly and up to date. The company also then need to save, servers, and storage devices, to prevent overheating you can also heat need devices that cost money. With cloud computing several of this hiring will be. If these companies use, or a Migration to cloud computing, you need only one Computer, and sometimes on a single server, the operations work without problems. All other computers are then outsourced to the clouds, the Server and storage devices in different locations can be enabled or disabled, according to the company’s computing demand. No more expensive software licenses, no more need for multiple servers and support of the people, all of them. These companies will then pay the cloud computing provider as they use the services, it is like a Taxi-and pay device during the measurement.
Virtualization is a technology that helps businesses and individuals in order to make your Computer, applications, storage devices and servers more efficiently. This can be defined as the ability to run multiple instances of something (operating system) in something (computers) when it is only an example. There are different types of virtualization. Server virtualization Is type of virtualization that consolidates multiple physical servers to virtual servers, and then was run on a single physical server. Application virtualization – an application that is executed on another computer where it is installed and you can Remote access it from another computer. Example of this is the virtualization of desktop, presentation virtualization – runs on a framework known as Citrix, the application is then run in a different computer however, you can also see on the customer screen. Network virtualization This type of virtualisation uses the network in a carved up way, which, after being executed, for multiple purposes, through the switch, NIC, VLAN, storage devices, and other control devices of a network Storage-virtualization is that storage devices will be consolidated and managed in virtual memory, the Server in which it is connected, the device is aware of the physical location of the virtualized storage.
Cloud Computing and virtualization are two different technologies that will be exchanged most of the time. These technologies work without the other. Even though cloud computing is used even better if the virtualization of desktop is done first, since the majority of Cloud-computing means that several virtual servers and storage devices, or which multi-tenancy can call. Virtualization, on the other hand, allows you to save a company or a private person, in their computing needs and resources through virtualized version of a physical resource in the same resource. For example, A server, only a 30 per cent, most of the times, and the server B is used only to 50 percent, These two can be combined to a virtual server to A server B, and therefore is not physically connected to the Server-A more. This means that you will be able to save money and resources to remove A server from the equation.
More in-depth explanation of Server virtualization
Virtualized servers on a physical server to run side by side in the same environment without any compatibility problems, since these virtual servers are isolated and, then, encapsulated with different layers. From the Hardware layer, Virtualization layer and different environments, such as operating systems and applications. at the Hardware layer to each virtual server has dedicated to the memory, hardrive and processor allocated to the physical server. Therefore, as it is a space of Physical server. Most of the times the Virtualization instead of converted 20 physical servers, turning nineteen this physical server in a server virtualized.
Cloud computing, on the other hand, does not use the physical resources access to these resources operating for servers, applications, systems, storage devices, etc. If you say you compute through a cloud, this means that the computing resources are outsourced to vendors while you pay these providers for what you use. On the other hand, when using the conventional system of the computer, then you need to all devices, people and software that works for all without problems. Cloud computing means that these resources be made available to you, you take care of the thoughts of a company, without the maintenance, space for its equipment and software licenses because your supplier of cloud computing is this. All you have to do is sign in to your computer, monitor your use try release, or more servers according to your requirements.
