The term "virtualization" in the context of computing or cloud computing refers to the creation of virtual resources from a single resource of its kind, which appears as a few individual isolated resource s or environments. Users can use them as separate physical resources (like a virtual server, virtual storage device, virtual network switch, or even a virtual operating system for that subject).
Data accessibility has been made more accessible because of the flexible computing platforms made possible by cloud computing, which are now available to businesses and the general public. Instead of using personal devices, which don't give as much accessibility, the cloud computing model uses the web as its host to make data storage, security, recovery, analytics, networking, and database administration more easily accessible. Additionally, virtualization contributes to a clearer understanding of the cloud computing concept.
Virtualization enables cloud computing to give consumers the resources they need for computing. Through virtual servers, physical computer resources may be accessed effectively. Through cloud computing, virtualization has provided the digital world with several advantages for affordable accessibility and IT agility that is often associated with hardware.
Let us now interpret "What is Virtualization in Cloud Computing?"
Virtualization: What is it?
The process of creating a virtual desktop, operating system, network resource, or server is referred to as "virtualization." Cloud computing relies heavily and mostly on virtualization.
By doing this, it is ensured that the actual resource and its physical distribution are two independent things. As a result, it helps reduce the resource's cost or storage requirements. Furthermore, thanks to this technology, the end user may run numerous desktop operating systems and apps simultaneously on the same hardware and software.
The procedure also ensures the virtual emulation of products and services on the same computer without affecting the speed or the system's functionality.
The concept of virtualization was first conceived during the mainframe era, and as newer technologies advanced over time, it was eventually accomplished through specialized software.
- More flexible and efficient resource allocation.
- Increase development productivity.
- It reduces the cost of IT infrastructure.
- Scalability and remote access
- Disaster recovery and high availability
- Pay-per-use IT infrastructure on demand
- Allows the use of multiple operating systems.
The Hypervisor is the software used for virtualization. It is entirely responsible for separating the hardware from the operating system and allocating the required resources, such as CPU, memory, storage, and so on, for each invoked virtual resource.
A hypervisor is a software layer that sits between real and virtual resources and allows virtual machines to function. An emulator enables the host system to create numerous virtual machines and assign actual resources to them as needed. These virtual computers work on a single piece of hardware, lowering running expenses.
A host system that works with a hypervisor may be considered an entire virtual computing system since it has access to all the physical features of a system that can be accessed virtually.
A hypervisor is the foundation of virtualization and comes in two varieties. The Native Hypervisor, for example, works with the hardware of the host device to construct virtual computers. The next is the embedded Hypervisor, which operates as software on the host devices.
What is virtualization in cloud computing?
- We're all familiar with the cloud computing paradigm. A cloud provider will own all the physical resources in their environment, such as servers, storage devices, network devices, and applications and software. These physical resources are rented to clients on a pay-per-use basis.
- Cloud vendors will incur costs if they begin renting out new individual physical resources to each client. Because, in an ideal world, no physical resource is ever entirely depleted. This is why virtualization would be a great way to better use the silos (a silo is a storage system for bulk components). The cloud vendor, for example, can virtualize his one large server to give smaller, lower-spec servers to several clients.
Virtualization's Role in Cloud Computing
- Virtualization enables the benefits of cloud computing, such as ease of scaling up, security, fluid or flexible resources, etc. If another server is necessary, a virtual server will be quickly constructed, and a new server will be readied. When we need more memory, we increase the current virtual server configurations and now have the extra RAM we require.
- Virtualization is essential in cloud computing because it leverages virtualization technology to establish a virtual environment where users can access virtualized services without purchasing a hard drive. It is a framework that allows cloud computing companies to extend their virtual services into fully cloud-based solutions.
- As the basic technology of virtualization led cloud computing to scale up and gain even more critical characteristics, this "reflective" layer of computing operations provided organizations with vast room to offer and embrace innovations. Furthermore, cloud computing enables the creation of both private and public virtual ecosystems that individuals and businesses may use to access various services.
- As a result, virtualization is the key capability of the cloud computing business model.
Types of virtualization:
- Hardware Virtualization.
- Operating System Virtualization
- Server Virtualization.
- Storage Virtualization.
1) Hardware virtualization
Hardware virtualization occurs when the virtual machine software, or virtual machine management (VMM), is physically installed on the hardware system.
The primary responsibility of the Hypervisor is to regulate and monitor the CPU, memory, and other hardware resources. We may install multiple operating systems and run different apps on virtualized hardware systems.
Because operating virtual computers is significantly easier than running a real server, hardware virtualization is usually used for server platforms.
2) Operating System Virtualization
Operating system virtualization occurs when the virtual machine software, or virtual machine management (VMM), is placed on the host operating system rather than directly on the hardware system.
Operating System Virtualization is primarily used for cross-platform app testing.
3) Server Virtualization
Server virtualization occurs when virtual machine software, or virtual machine management (VMM), is directly installed on the server system.
Server virtualization divides a single physical server into several servers on demand and balances the load.
4) Storage Virtualization:
Storage virtualization combines physical storage from several network storage devices to appear as a single storage unit. Storage virtualization is also accomplished through the use of software programs.
Storage virtualization is mostly used for backup and recovery.
Important Virtualization Terminologies
Virtualization relies on a few key technologies, which are as follows:
- A virtual machine is a virtual kind of computer that functions under a hypervisor's supervision.
- Containers: These are lightweight virtual machines that are a subset of the same operating system instance or Hypervisor. They are a group of processes that execute with appropriate namespaces or process identifiers.
- Virtual network: This is a network that has been conceptually split and is present within the servers. These networks can be expanded to include several servers.
- Virtualization software: This software aids in virtualization deployment on computer devices.
