What is a Virtualization Service?

Virtualization is a technology that lets you create useful IT services using resources that are traditionally bound to hardware. It allows you to use a physical machine’s full capacity by distributing its capabilities among many users or environments. Virtualization’s widespread applicability helped reduce vendor lock-in and made it the foundation of cloud computing. It’s so prevalent across enterprises today that specialized virtualization management software is often needed to help keep track of it all.

How does Virtualization work?

Software called hypervisors separate the physical resources from the virtual environments—the things that need those resources. Hypervisors can sit on top of an operating system (like on a laptop) or be installed directly onto hardware (like a server), which is how most enterprises virtualize. Hypervisors take your physical resources and divide them up so that virtual environments can use them.
Resources are partitioned as needed from the physical environment to the many virtual environments. Users interact with and run computations within the virtual environment (typically called a guest machine or virtual machine). The virtual machine functions as a single data file. And like any digital file, it can be moved from one computer to another, opened in either one and be expected to work the same.
When the virtual environment is running and a user or program issues an instruction that requires additional resources from the physical environment, the hypervisor relays the request to the physical system and caches the changes—which all happens at close to native speed.

The Benefits of Virtualization

REDUNDANCY AND INSTANT FAILOVER ABILITIES
System crashes can cause insurmountable losses for enterprises, but thankfully, virtualization allows images on one machine to be instantly re-imaged on another for easy recovery in case of system crash. Without redundancy, many businesses would get into numerous problems over lost data. Virtualization provides instant failover abilities which make things more efficient.
SMOOTH MIGRATION OF RESOURCES
Virtualization makes it easy to switch from physical to virtual infrastructure as need arises. Different technologies allow for virtual disk storage, but you can quickly turn to physical storage. You also have the option to migrate from fully allocated virtual disk to a thin-provisioned virtual disk. This way, administrators have the power to prevent wastage of resources by provisioning only what’s needed at a certain time without a negative impact on businesses.
VIRTUAL FIREWALLS AND SECURITY
Security is a major challenge for businesses, but virtualization provides a solution. Business ventures can benefit from virtual firewalls to protect access and data at lower costs than traditional methods. It is also beneficial to have an experienced security professional looking out for your security needs. Virtual security involves the use of advanced controls such as a virtual switch to protect against malicious attacks coming from unverified sources.
IMPROVED IT SUPPORT
Companies must provide excellent customer support if they intend to keep or maintain their customers. This can be quite a challenge for ventures without enough manpower to provide customer support when it is needed. Moving to the virtual space is a great solution that instantly improves IT support to ensure a seamless flow of data for various operations.
REDUCED COSTS AND A GREENER ENVIRONMENT 
The traditional one enterprise app for one server model set the stage for increased costs and underutilized servers in the traditional hardware model. This is the opposite with virtualization as machines are consolidated across fewer physical servers reducing compatibility issues and cutting down costs. There is no wastage with this approach that makes sure virtual machines are allocated just the resources they need. In so doing virtualization reduces data center carbon footprint which goes a long way in preserving the environment.
