Xen Vps Hosting. If you want to find good and reliable Xen Vps Hosting you have to be able to evaluate different Xen Vps hosts, but first you need to understand more about Xen and virtualization. Read this post to learn more. In the end I will share some links to some of the best and most reliable Xen Vps hosts.
Lets get you started.
What is Xen? Xen is a hypervisor. Hypervisor is a software which enables several operating systems to run on the same hardware ( server ).
In fact hypervisor is controlling the hardware, allocating its resources to each operating system. There are Type I and Type II hypervisors.
Main difference is:
- Type I: Installed as a bare metal install ( directly without OS on the server).
- Type II: Installed on top of already installed OS.
Most popular type I hypervisors are:
- Red Hat Enterprise Virtualization (RHEV)
- Citrix XenServer
- Microsoft Windows Server 2012 Hyper-V
- VMware vSphere / ESXi
And what about XEN?
Xen was started as a research project in 2003, on university of Cambridge.
Citrix acquired XenSource Inc in 2007, and developed Citrix XenServer.
Recently Citrix announced that Xenserver 6.2 will beome full open source.
Important feature of Xen is its robustness and small footprint ( very, very lean code). It is important to know that some of the biggest clouds today are running on Xen. XEN is probably the most widespread virtualization technology used for vps hosting today.
Biggest advantage of XEN virtualisation is isolation.
Other important advantages of XEN vps is security and stability.
Some of the most reliable VPS hosts today use XEN because of these features.
XEN is actually the only open source type 1 baremetal hypervisor.
Remember baremetal means that XEN is installed directly on server without OS.
Exactly this fact is the main reason why XEN is a superior method of VPS virtualization, enabling:
- Small footprint
If you want to go into more details on how exactly XEN virtualization works read this post.
For even more details on virtualization and XEN architecture read this post.
If you are not technical person it is important to know that:
- XEN is installed directly on hardware.
- XEN works by managing hardware.
- XEN enables simultaneous different operating systems on the same hardware.
XEN approach to virtualization is very different from another popular virtualization method OpenVZ/Virtuozzo. This post explains very good pros and cons of both methods.
Most sources will agree that XEN approach to virtualizaion is superior to openVZ.
XEN will create VPS which characteristics are very close to characteristics of dedicated server.
XEN VPS is very stable and you can customize it almost as dedicated server.
Important advantage of XEN is that it manages memory and resources much better than OpenVZ.
One of advantages of OpenVZ is that it is often slightly cheaper than XEN vps.
Main reason for this is because it is harder to oversell XEN ( but not impossible).
These are some of the most known XEN VPS hosts:
Linode is probably the most famous XEN VPS host.
They have been around since 2003, and right now are one of most reliable VPS hosts around. Linode usually receives very good customer reviews and is perceived as one of most reliable VPS hosts.They offer reasonable range of VPS plans.
Important and very interesting offer is Linode Managed.
For non technical people managing VPS hosting can be difficult. I wrote about managed VPS hosting in one of earlier posts.
If you can afford it I strongly suggest managed VPS.
Another interesting option for XEN vps hosting is PhotonVps.
One of the things I always try to mention when choosing your web host is how long has company been around. This is very important as the age of the company shows that they have been in this business for a long time and that they have the experience of dealing with many different issues and challenges.
PhotonVPS has been around since 90ies. They offer large range of different hosting plans.
They also receive good reviews from real people ( not bogus review sites).
I hope I was able to help you with your quest for XEN Vps hosting.
