A method for separating a service from the underlying physical delivery of that service is virtualization cloud computing. It entails making a virtual copy of any object, including computer hardware. It was initially created in the age of mainframes. It involves creating a virtual or software-created version of a computing resource rather than the actual version of the same resource using specialized software. The use and flexibility of hardware can be increased by running multiple operating systems and programs concurrently on the same computer and hardware with the aid of virtualization.
Hardware-reduction, and energy-saving strategies employed by cloud providers. A single physical instance of a resource or program can now be shared by numerous consumers and businesses at once thanks to virtualization. Giving the physical storage a logical name and immediately delivering a pointer to the physical resource achieves this. Hardware virtualization is necessary to properly deliver Infrastructure-as-a-Service (IaaS) solutions for virtualization cloud computing. The term “virtualization” is widely used in this context to refer to both processes. Virtualization technologies offer a virtual environment for networking, memory, storage, and application execution in addition to a virtual environment for program execution. In this article, animalworlds.vn will discuss virtualization cloud computing and 6 best types of virtualization.
Benefits of Virtualization Cloud Computing
- More flexible and efficient allocation of resources.
- Enhance development productivity.
- It lowers the cost of IT infrastructure.
- Remote access and rapid scalability.
- High availability and disaster recovery.
- Pay peruse of the IT infrastructure on demand.
- Enables running multiple operating systems.
Drawback of Virtualization Cloud Computing
- High Initial Investment: Although clouds require a large upfront investment, it is also true that doing so will help businesses cut costs.
- Learning New Infrastructure: Businesses have switched from using servers to the cloud, thus in order to have highly skilled employees who can work with the cloud effortlessly, you either need to hire new personnel or train existing staff.
- Risk of Data: Hosting data on third-party sites puts the data at risk since it increases the likelihood that it will be attacked by a hacker or cracker.
Characteristics of Virtualization Cloud Computing
- Increased Security: Delivering a secure, controlled execution environment is made possible by the ability to entirely transparently control the execution of a guest program. The virtual machine typically receives all of the operations from the guest programs and translates and applies them to the host applications.
- Managed Execution: The most pertinent aspects are sharing, aggregation, emulation, and isolation.
- Sharing: Virtualization enables the creation of several computing environments on a single host.
- Aggregation: Although virtualization also makes it feasible for aggregation, which is the opposite operation, multiple guests can share physical resources.
Types of Virtualization Cloud Computing
1. Application Virtualization: Users can remotely access programs hosted on servers thanks to this technology. The program can still be run on a local workstation through the internet while the server keeps all user data and other program features. An example of this would be a user who needs to utilize two different versions of the same piece of software. Technologies that make use of application virtualization include hosted apps and packaged apps.
2. Network Virtualization: The ability to control a large number of virtual networks, each having a unique control and data scheme. On top of a single physical network, it coexists. It can be controlled by several parties who might not wish to exchange information. It is possible to swiftly and easily set up virtual networks, logical switches, routers, firewalls, load balancers, Virtual Private Networks (VPN), and workload security with the aid of network virtualization.
3. Desktop Virtualization: For users thanks to desktop virtualization. It allows the user to virtually access their desktop from any location using a different machine. If users want to use an operating system other than Windows Server, they must use a virtual desktop. User mobility, portability, and simple management of software installation, updates, and patches are the key advantages of desktop virtualization.
4. Storage Virtualization: A collection of servers used for storage virtualization is managed by a virtual storage system. Because they are unaware of the actual location of their data, the servers behave more like worker bees in a hive. It makes it possible to manage and utilize storage from several sources as one repository. Storage virtualization software ensures efficient operations, consistent performance, and a continuous variety of complex capabilities despite changes, issues, and variances in the underlying hardware.
5. Server Virtualization: The ability to conceal server resources is provided by this sort of virtualization. Here, numerous virtual servers are created by changing the identity number, processors, and central server (physical server). Each system can therefore independently execute its operating systems. when each sub-server is aware of who the central server is. It enhances performance and reduces operating expenses by transferring core server resources into a sub-server resource. It aids in the transition to virtualization, reduces energy use, lowers infrastructure costs, etc.
6. Data Virtualization: Without understanding more about the technological specifics, such as how data is gathered, saved, and structured, with this type of virtualization, data is gathered from many sources and managed in one place. The data is then logically organized so that users and other interested parties and stakeholders can remotely access its virtual view using a number of cloud services. Offering their services are such big, strong companies as Oracle, IBM, At scale, Cdata, etc.
