Operating System level virtualization and its benefits

Organizations all around the globe are utilizing virtualization in order to eliminate needs such as physical space for the servers, expenses related to CapEx and OpEx, and power consumption. Virtualization is a technology that is revolutionizing the computing industry with its countless benefits and providing solutions for these problems as well.

Organizations are also benefiting from virtualization as this technology helps in simplification of their operations, induces agility in their IT processes and increases the uptime for their servers and time-sensitive applications. 

There are seven types of virtualizations out of which we will discuss OS-level virtualization today. In this article, you will learn what OS-level virtualization is, what are its types and advantages.

Operating system level virtualization

Operating system level virtualization is one of the server virtualization methods. In this virtualization, a single server is used to run more than one operating systems instead of dedicating one server per OS type. The kernel of the host operating system allows the creation of multiple isolated instances referred to sometimes as software containers or virtual private servers.

OS-level virtualization is extensively used in virtual hosting environments for hardware resource allocation among multiple isolated users. Some administrators use it for consolidation of server hardware as well. Through this technique, space and cost related to servers are saved as the requirement of purchasing servers for different OS is not required anymore and management is simplified.

Benefits of Operating System Level Virtualization

1.     This virtualization type is economical as the applications present in software containers can utilize most of the resources of the machine.

2.     In terms of creating guest servers, this technique is quite efficient. OS-level virtualization is perfect for cost-efficient and convenient for web hosting companies where there is a requirement of a blade on which virtual web servers are running simultaneously and patches applied on the host server are effective on all the guests. Companies that need to manage multiple similar servers in the same data center can also use OS-level virtualization.

3.     Companies can have a greater return on investment in server hardware purchases with the help of this virtualization as the hardware is efficiently used which in turn makes operational activities effective as well.

4.     Data center management staff is reduced greatly as the service and maintenance of the OS-level based infrastructure is smaller in number and easier to manage.

5.     Tools for workload balancing, capacity planning, and monitoring are available in the virtualized environment which is why maintaining performance is an easy task in such an environment.

6.     Deployment of virtual servers and OS is quite agile and fast as compared to the traditional ones because the VMs can be readied beforehand and deployed as necessary but in case of the traditional ones, all the machines need to be prepared individually. Virtual machines can be made with ease as their templates are reusable which is why OS-level virtualization has a high uptime and fast backup deployment.

This was our take on operating system level virtualization and its advantages. The world is currently facing many issues at the moment. Scarce resources and environmental pollution are two of the impending problems that are related to the IT industry. It is a fact that no company can survive the future without employing virtualization.
