Learn the pros and cons of desktop virtualization technologies by allowing Endpoint Engineers to help you
leverage virtualization to its fullest. Below are some useful explanations of virtualization and its benefits.
Full Virtualization
Full virtualization uses specific software called a hypervisor. The hypervisor interacts straight with the physical server’s CPU and disk space and serves as a virtual server’s operating systems program.
Hence, the hypervisor keeps each virtual server wholly independent and unaware of the separate virtual servers working on the physical machine.
The hypervisor observes the physical server’s resources. As virtual servers run applications, the hypervisor sends resources from the physical machine to the relevant virtual server.
Para-Virtualization
The para-virtualization program is a little different. Unlike the full virtualization technique, the guest servers in a para-virtualization system are aware of one another.
Therefore, a para-virtualization hypervisor doesn’t require as much processing power to control the guest operating systems.
Each OS is already conscious of the demands the other operating systems are setting on the physical server. The entire system works collectively as a cohesive unit.
OS-Level Virtualization
An OS-level virtualization program doesn’t use a hypervisor at all. Instead, the virtualization ability is part of the host OS, which fulfills all the functions of a fully virtualized hypervisor.
The most unusual limitation of this approach is that all the guest servers must work on the same OS. Hence, each virtual server remains free from all the others, but you can’t mix-match operating systems between them.
As all the guest operating systems must be the same, this is called a homogeneous environment.
Benefits
Increased reliability and higher availability
Using shared storage software minimizes downtime since data is independent of the computing resources. The degradation of a server component doesn’t impact the data itself.
Better
Scalability
This is an essential attribute of nearly any aspect of today’s data center and is especially important for data storage.
Central Management & simplicity
One pool of storage to manage, which is operationally easier, compared to managing storage server by server.
Advanced data features
Shared storage systems are designed as specialized storage solutions. Their task is to store data in a reliable and effective manner, and thus come with many data storage technologies which enable just this.
