Virtual private servers connect shared Web hosting services and dedicated hosting services by filling the gap between them. Because virtual dedicated servers can have their own copy of the operating system, VPS provides the user with super-user privileges in the operating system. VPS enables the user to install any kind of software that is capable of running on that operating system.

Perhaps the best way to approach the virtual server is the idea of a virtual machine. A VM allows you to run an emulation of a computer within your computer, drawing on the resources of the physical one –  disk space, RAM, CPU, etc. This tactic allows you to run an entirely separate operating system (OS) solely for the purposes of the VM, even if its type and version of OS are identical to what’s on your hardware.
During the Nutanix demo, Andy did what he does better than anyone I know – he drew a full stack of Nutanix on the whiteboard and covered the hyperconverged technology from end to end. I was intrigued by Andy’s presentation of hyperconvergence. For more information see the results of Gartner’s Peer Insights: Nutanix vs VMware Review. Some folks say Nutanix is the solution to the VMware tax.
Virtual Private Server is one of the best servers if you are looking for dedicated server functionality at a lesser price. VPS goes economical once you go for a unmanaged plan. In unmanaged plan you root login details where you can manage your server. Unlike the managed VPS, your do not bear pain of managing server optimization, server security. All such procedures are taken care by our technician. Unmanaged VPS are for those people who have sound knowledge of technical details of Linux. Once you have the technical knowledge you can manage any operating system and other details for testing or running a hosting server for your customers.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.[3]
