We support both Operating System virtualisation (using OpenVZ) and Native virtualisation (using KVM, including VIRTIO for increased disk performance.)
VPS Advice - Buying Guidelines
When buying or leasing a VPS you are in effect buying these components:-
Bandwith: Is there enough for your needs and is the device located physically close to your users? If there is a large physical distance (many cheap providers are located in the US) things will be less responsive. Depending on what you're hosting this could matter, or it might not.
- Our servers are in a Tier4 data center only 2ms from the London INternet eXchange point (LINX) with more than 20Gbps redundant access.
RAM: A VPS can show that it has 512MB of memory, but this might not be instantly available when your VPS needs it. Much like airlines oversell plane tickets a VPS host can over sell RAM by swapping your applications to disk. This has the effect that things could be up to 100X slower until some RAM is freed up and the your application is swapped back in.
- Our servers have more than enough RAM, and in fact do not even have swap memory allocated.
CPU: This is the most easily over sold component since in most environments it is the least used. The key is to ensure that computational tasks are responsive - perhaps log the time it takes to run certain key functions to ensure you're not on an overloaded host.
- We operate Dual Quad core Intel Xeon servers and would be happy to show CPU utilisation graphs to prove we have the reasouces to accommodate you.
Hard drives: Hard drives start writing data on the outer edge of their platters, data access here is almost 1.5X faster than toward the inside.
- We use RAID1+0 (for best redundancy and best performance) and ensure that when individual drives are more 50% used we move data onto another drive.
You could have access to a standard Linux VPS in less than 1hr (perhaps a little longer over weekends) - We have images available for CentOS, Debian and Ubuntu.
Commercial Internet Solutions were the complete package when it came to service. As a total IT novice, I need to use someone whom I feel is 100% trustworthy and in whom I have total confidence. We were dealing with a firm who we never felt were being totally open with us and as a result we felt the need to move the server away from them to a firm who we were completely comfortable with. both in terms of pricing and professionalism. The service provided to RVB was clear and utterly professional and as a result I would have no hesitation in recommending their services. Christopher Birts, RVB Currency
We support both:
Operating System virtualisation (using OpenVZ). This is flexbile and cheap, but won't work is all situations. We have ready made templates for CentOS 5, Debian 6.0 (squeeze) and Ubuntu Lucid.
- We use this technology to host our Asterisk IPBX products.
- not suitable for Windows hosting or if you intend to run Java applications.
- will be delivered with the basics set up and a single IP address. Webmin can be installed if required to allow remote administration. Cost are from £150pa for 512MB RAM and 15GB diskspace.
and Native virtualisation (using KVM). This is more expensive, but will host any operating system required i.e. Windows Small Business Server essentials or any version of Linux. We can not publish pricing for this since 3rd party licenses might be required. Please contact us with details for a quote. We support the Virtio drivers for increased performance.
