NixVPS - A Virtual Private Server Solution

  What is NixVPS?

NixVPS is a Virtual Private Server solution that is at current the most advanced step in server virtualization technology. It is used to partition a single physical server into many isolated virtual private servers where each virtual private server looks and behaves exactly like a real networked server system, complete with its own set of init scripts, users, processes, filesystem, etc.

  NixVPS - The Basics

Each NixVPS instance behaves exactly like an isolated stand-alone server


- has its own processes, users, files and provides full root access
- has its own IP addresses, port numbers, filtering and routing rules
- has its own configuration files for the system and app. software
- has its own versions of system libraries or modify existing ones
- can delete, add, modify any file, including files in /root, and install its own application software or custom configure/modify root application software

  NixVPS - The Technology

Here at Nixperience, we use the Xen virtualization system because it's simply the state of the art in virtual private server solutioning. With Xen, end users enjoy short cpu, hard drive and network latencies, a direct result of the accurate scheduling mechanism deployed by Xen.

Xen is totally different from other virtualization technologies like UML, vServer or Virtuozzo. In Xen, memory is not shared and is not burstable among users. The physical memory and physical disk space is split up and given to each Xen instance as a dedicated resource. There is no sharing and certainly not a chance for overselling by the provider. Each Xen instance has its own dedicated resource and that's the beauty of the technology.

Xen or officially known as "Xen Hypervisor",  is a unique open source technology, developed collaboratively by the world's best engineers at over 20 of the most innovative data center solution vendors, including Intel, AMD, Cisco, Dell, Egenera, HP, IBM, Mellanox, Network Appliance, Novell, Red Hat, SGI, Sun, Unisys, Veritas, Voltaire, and XenSource. Xen is licensed under the GNU General Public License (GPL2) and is therefore an Open Source Technology. More information about Xen can

  NixVPS - Benefits Over a Dedicated Server

NixVPS gives you the functionality of a dedicated server at a fraction of the cost.

Data Integrity
NixVPS provides you with reliability, build on a RAID 1 array to ensure data integrity and maximum uptime. Additional access to backup facilities can also be arranged for maximum data integrity and maintainability.

All NixVPS instances come complete with management. The nature of a virtual private server means we can manage all aspects of software upgrading and patching.

NixVPS is functionally equal to a dedicated server.

Resource Efficient
Resources are dedicated to each instance. Resources are also easily scalable to suit your needs as you grow.

  NixVPS - Benefits Over a Shared Hosting

NixVPS gives you root access to the system, this allows you to modify server configuration files, install applications or modify system software, in a shared environment you have to rely on server settings that are a 'best fit' for all clients and this may not suit your specific needs.

Your NixVPS file system is not accessible or viewable by any other NixVPS owner, unlike a shared environment where anyone with shell access can browse through your files, NixVPS ensures full privacy and security.

In a shared hosting environment you are 'held hostage' to the actions of others, if another shared account runs a script that crashes the server then your site goes down too. With NixVPS, you have complete resource isolation, no matter what another NixVPS user does, it will not affect your server.

In a shared environment, resources goes to the site 'that shouts the loudest'. In other words, a large site can potentially drain all resources and leave yours performing badly. In a NixVPS environment, you are guaranteed a set of resources to ensure your site always performs at full speed. These resource guarantees ensure that other NixVPS servers have no affect on the performance of your site.

  NixVPS - Coming Good with Hardware

Nixperience places reliability above all else. As such, physical hardware monitoring is vital for the smooth provisioning of any NixVPS solution. NixVPS instances are tightly monitored and their individual CPU loads are charted carefully to ensure smooth and reliable functionality for all concerned. Nixperience engineers will be on-hand to recommend alternative solutions should a NixVPS solution be unsuitable for your needs.
