Virtualization or Virtual Private Server is division of a physical server and its resources into multiple servers where more than one user operates mutually. The concept of virtualization is vast and the upgraded solutions of virtual servers are not limited to the implementation or configuration of the equipment. It goes beyond the limitations and extends to three aspects of virtualization that are application virtualization, server virtualization and presentation virtualization.
Application server is a technology that creates a unique environment within the operating system to run applications dynamically. Talking about server virtualization, the resources underlying in the server are either hidden or masked and the physical server is distributed into multiple virtual server to create that virtual environment. It can either run a couple of virtual servers or support a dozens of server on single physical machine. This was initially put into action for experiment purpose, as it was easier, cost-effective and fast process than the real server. However, with time virtualization gained immense popularity and now it is one of the highly used technology.
Advantages of Virtualization
- Reduced operational cost
The biggest advantage associated with VPS hosting is it is cost-effective that reduces the burden of investing huge amount in infrastructure equipment or for hiring. With virtualization, users get access to a same level of software and server performance, availability and scalability without spending more on it, which further cuts down your capital expenditure. Once the server is virtualized, all operations are automatized that lowers time-consuming processes and operational expenses.
- Energy Efficient
As the size of the hardware and footprint of server is reduced considerably via virtualization, it burns up less energy, making the technology energy efficient. With virtualization, companies gain the ability to diminish the amount of carbon emission that could further make a huge difference.
- Easy administration
When the server goes down, the administrator needs to make his trip to the prime location of the VPS to perform the necessary alterations or manage the server. Virtualization enables you to access the consoles of the virtual server from the workstation itself that eliminates the need to visit the server virtually.
- Back up and disaster recovery
To add to this, back up and disaster recovery is another crucial feature of Virtual Private Servers. Virtualization lets you replicate your server disk immediately and maintain a backup, which is entirely transparent to users. This promotes business continuity and with virtualization, the possibility of your business turning down is relatively low.
