Cloud computing is a technology that many companies use, which wants to reduce costs, and access programs and applications that are not physically installed in their computer or server. The concept of electricity probably compares how this technology works, even though the consumer does not know where and how electricity is produced, consumers still have access to electricity whenever they are plugging them in a device and It needs to be turned on. This concept is almost like the cloud computing, but the main type of communication used with this technique is the internet. Cloud computing, defined by NIST or National Institute of Standard and Technology, is a technology that provides scalable IT capabilities to be offered as services through the Internet to many users, many users then reduce costs IT will share the resources and as a result the computing capacity will be high.
Think of it this way; A company that uses a computer will need several systems to provide services, communicate and store information, this also means that you have as many computer licenses, servers and storage devices as computer You will need because your company grows. Many people are working all day long to ensure that the servers, applications and storage devices are working properly and there are updates. The company will also need space to store these servers and storage devices, and you will also need cooling appliances to stop overheating, in which money is spent. Many of these purchases are discontinued with cloud computing. If these companies use or migrate cloud computing, they only need a computer and sometimes a single server to run the business smoothly. All other computing needs are outsourced to the clouds, which are server and storage devices in different places, which can be turned on or off based on the computing demand of the company. No more expensive software licenses, many servers are not required and support people to maintain all of these. This company will later pay the cloud computing provider because they use the services, it is like taking a cab and paying through the meter.
It can be defined as running several instances of some (operating system) operating in some computer (when it is designed to run only one instance). There are different types of virtualization. Server virtualization – is a type of virtualization that integrates many physical servers for virtual servers and then runs on the same physical server. Application Virtualization – An application is run on another host where it is installed and remotely accessed from a different computer. The example is desktop virtualization, running on a mat frame like Presentation Virtualization – Citrix, the application is then run in a different host, although the client can also be viewed on the screen. Network Virtualization – This kind of virtualization uses the network carvings, which can then be run through the switch, NIC, VLAN, storage device, and other devices for many purposes, which can control network storage virtualization – This means the storage device is then consolidated and managed in a virtual storage device.
Cloud Computing and Virtualization are two separate technologies that interconnect most of the time. These techniques will work without the other. However, cloud computing is better used if desktop virtualization is done first because most virtual cloud computing requires many virtual servers and storage devices to work or you can call multitense. Virtualization, on the other hand, enables a business or a person to create a virtualized version of physical resources in the same resource and save their computing needs and resources. For example, the use of Server A, only 30 percent of most of the time and server B is used by only 50 percent, both of these can be combined together by creating Virtual Server A in Server B and therefore physically the server A Not used. This means that you save money and resources by removing server A from the equation.
Server Virtualization Deep Details
In a physical server, virtualized servers run side by side in the same environment without compatibility issues, because these virtual servers are isolated and then encapsulate with different layers. With hardware layers, virtualization layers and various environments such as operating systems and applications. Each virtual server in the hardware layer has a dedicated memory, hardware and processor which is allocated for it in the physical server. Like it’s an operational physical server. Most time of liaison converts 20 physical servers by turning nineteen into physical server
