What is a VPS?
A Virtual Private Server (called as Virtual Dedicated Server or VDS)is a method of partitioning a physical server computer into multiple servers such that has the appearance and capabilities of running on its own dedicated machine. Through the software installed on the server, accounts are created in complete isolation from another.Each Virtual Server can run on its own full-fledged operating system, each server can be independently rebooted. Each Virtual Private Server looks and behaves exactly like a real networked server system, complete with its own set of scripts, users, processes, filesystems, etc.
The practice of partitioning a single server so that it appears as multiple servers has long been common practice in mainframe computers, but has been a resurgence lately with the development of virtualization software and technologies for other architectures.
Instead of allowing the kernel or operating system to interface directly with hardware components, virtualization software intercepts requests, queues them, and manages their interpretation.
How does VPS work ?
What can I do with a VPS ?
A Virtual Private Server (VPS) is capable of hosting a business website, a database driven online store, or a corporate intranet. Many companies use Virtual Private Servers as dedicated mail servers or development platforms.

Virtual Private Servers are the most advanced step in server virtualization technology. Virtual Private Servers are fully managed with complete management package. This includes hardware management, network management, operating system and software support, proactive security patches and updates, proactive monitoring, firewall, spam prevention, server hardening and more.
All VPS accounts run the latest of CentOS Linux 5 by default and include full root access.
The Flexibility of a VPS
Users share system resources, such as the CPU and memory, but unlike shared hosting (a virtual host on a shared hardware server) the file system is fully partitioned. This means you would get a guaranteed share of the server's resources, while full root access allowed you to completely customize the virtual server, adding or changing modules and installing your own software
Shell Root Access in a VPS Account
Generally, VPS account provides you a root login and full root access, so you have the possibility to install and run your own scripts or software on your Virtual Private Server.
A VPS account generally is limited by
- Quantity of RAM
- CPU usage or CPU Processes
- Amount of disk space
- Transfer or Bandwidth
VPS Memory
Memory for each VPS hosting account varies. The RAM of each VPS is isolated from the other virtual servers cans the RAM usage never affects any other virtual server in the physical server. You can confirm the guaranteed memory in VPS plans page. The guaranteed memory is the minimum amount of RAM allowed for your virtual server.
VPS CPU Usage
As the RAM, a limited CPU usage is dedicated for your Virtual Private Server, mostly equal sharing between all the CPU.
VPS Disk Space
With a Virtual Private Server you have the possibility to host several websites and install your own scripts and software in them. So it's important to choose a VPS hosting plan with a huge amount of disk space! In DigitalSwift ｙou get the Best of It, this amount of Huge Disk Space is not provided anywhere.
VPS Transfer Usage or Bandwidth ?
Bandwidth is the monthly amount of data transfer that you are allowed to use. In general, if you have a commercial site or a site that generates a lot of traffic, you should consider getting additional bandwidth. If you have a basic, personal site that you have set up for friends and family, you probably do not need to order additional bandwidth. Most providers do not provide you Unlimited Bandwidth, and that is the reason why Digital Swift provides you with Unlimited Bandwidth ie. You can transfer any amount of data of your need.
How is the Bandwidth usage Calculated?
Upstream and downstream bandwidth is tracked and aggregated for all IP's registered to your account.

This allows complex hosting configurations that cannot be run in shared hosting but under a VPS.
