A searchable database of all companies with VPS Hosting capability around the world.
What is VPS?
Virtual private servers or Virtual dedicated servers are a form of virtualization that split a single physical server into multiple virtual servers. The practice of partitioning a single server so that it appears as multiple servers has long been common practice in mainframe computers, but has seen a resurgence lately with the development of software and technologies such as VMware, Xen, FreeBSD Jail, User-mode Linux, Linux-VServer, FreeVPS, OpenVZ, and Virtuozzo.
The benefits of VPS Hosting are many:
- You have root access to the server
- Install any application you want, ROR, PHP, Tomcat, Oracle...
- Have just about any flavour of linux, Debian, Suse, Redhat...
- Some virtualization software lets you use different flavours of Windows
- Guaranteed uptime with most suppliers
What is Xen?
Xen is an open source virtual machine monitor, developed by the University of Cambridge and now XenSource. It is intended to run up to 100 full featured OSs on a single computer. Operating systems must be explicitly modified ("ported") to run on Xen (although compatibility is maintained for user applications). This enables Xen to achieve high performance virtualization without special hardware support.
What is Virtuozzo?
Virtuozzo is a proprietary operating system virtualization product produced by SWsoft, Inc. A version that supports Linux has been available since 2001; a version that supports Microsoft Windows became available in 2005.
Note: We don't index quite a few providers who use Virtuozzo as they do not specify guaranteed RAM (not burst RAM) on their hosting plans. Having said that, guaranteed is not necessarily guaranteed because Virtuozzo services (unlike Xen) can be oversold.
