Generally, IT organizations deploy a panel of servers for running different sorts of applications. In a few words, dedicated physical servers are meant to run a specific application. Subsequently, servers stay idle and remain unused for most of the time. Hence, the Servers only run a fraction of their full capacity which leads to non-agile mechanisms. Servers having the potential to operate at higher capacity tend to work at limited bandwidth with reduced consumption. Subsequently, resources that are not being consumed lead to higher operating costs. In efforts to save from drawbacks, a virtualization concept was introduced. In conclusion, an organization is surrounded by uncountable virtualization benefits.
What Does Virtualization Mean? Understanding the Simplest
Virtualization is the process of creating software or virtual machines for use with dedicated hardware layers. With this, we mean creating virtual space without the knowledge of the user as they perceive using the resource differently but actually multiple users are accessing the same resource. Basically, it creates software or virtual architecture of different IT components like virtual applications, servers, storage, and networks. In conclusion, Virtualization is the technology that forms the base for cloud computing.
9 Benefits – Adapting Best for Business
- Cutoff IT expenses
- Adding agility to variable-sized business
- Boosting efficiency, responsiveness, and productivity
- Less capital and operational costs
- Improved compatibility between applications and resources
- Simple disaster recovery
- Easy data center management
- Faster availability of resources
- Greater workload mobility and automated operations
How Virtual Network Works? Stepping Into Virtual Machines
Have you heard about the term Virtualization 101? Virtualization 101 refers to creating a virtual version of all the IT assets running within the organization. Previously, the x86 server architecture deployed multiple servers, each with a different operational capacity to keep up the pace with high storage and processing demands. Consequently, this led to huge inefficiencies and excessive operating costs.
Later and now, we entered into the virtual age which totally relies on the simulation of hardware components and thus creating a virtual computer space. This virtual architecture setups IT organizations to run, execute more than one virtual system, multiple operating systems, applications but all of them on a single server. Consequently, you get the benefit of huge scalability and improved resource efficiency.
Firstly, a virtual computer system is also known as a virtual machine or VM. With VM, we mean a tight bundle of software containers along with an operating system and application inside. Moreover, each self-contained VM works totally independently. Installing multiple virtual machines on a single computer lets several OS and apps to run over one physical server. Commonly, this is referred to as a host. However, a software layer called “hypervisor” decouples the virtual machines from the host. Additionally, hypervisors are responsible to allocate computing resources to each virtual machine as required.
Key Properties of Virtual Machines
Partitioning
- Executing multiple OS on a single physical machine.
- Allocating system resources among virtual machines.
Isolation
- Give fault and security isolation at the hardware level.
- Retain performance with advanced resource controls.
Encapsulation
- Backup the entire state of a virtual machine to files.
- Move and copy virtual machines similar to files.
Hardware Independence
- Move or migrate any virtual machine to any physical server.
Types of Virtualization – Fit for Different Organizational Needs
So, Virtualization is broadly classified into different categories.
1. Network virtualization
2. Server virtualization
3. Desktop virtualization
4. Hardware virtualization
5. Software virtualization
6. Storage virtualization
In the final analysis…
Hence server virtualization is the most common. Server virtualization includes getting resources from one or more physical servers and allocating them to multiple virtual servers. Above all, Hypervisor lists among special tools used for virtualization purposes. Furthermore, you have various types of hypervisors like type 1 hypervisors ( also called bare-metal hypervisors that directly run on raw hardware, also referred to as virtual machine virtualization) and type 2 hypervisors (hypervisors that run on a guest OS). While the key players of the type 1 market include VMware, Microsoft, and Citrix. So, Red Hat’s Kernel-based Virtual Machine (KVM) is a popular type 2 product.
