NixVPS - A Virtual Private
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,
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 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

NixVPS - Benefits Over a Dedicated Server
NixVPS gives you the functionality of a dedicated server at a fraction of the
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
NixVPS is functionally equal to a dedicated server.
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
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.
