This is not ordinary dedicated server virtualization. We run Cloud VPS and the differences between them I already showed by pasting the links, but let me explain more about it in the thread.
What is Cloud VPS?
When you have the ordinary dedicated server virtualization you have it on one physical machine, which can be divided into the virtual machines with limites resources. Also, this type of virtualization is not self managed and you would not be able to do much in it.
The cloud VPS virtualization is based on Xen core and the actual virtual machines are created on the Hypervisors and SAN (Storage units) connected with CISCO router to the Internet (well CISCO we use).
In this case hypervisors are responsible for CPU and RAM and SAN for storage (the actual disk space)
We have hypervisors with 144GB RAM and Quad Core Xeon CPUs, that give the perfect performance for each of the virtual machines. Each of the resources are dedicated and their are not oversold and none burstable, which gives the ultimate performance for any type of the machine, no matter what size it is.
The cloud vps allows you to have unlimited resources for your machine, so for instance you start from 256MB RAM and can upgrade up to any size of it, the same comes with CPU, Disk Space and any other resources like IP addresses, network speed, etc.
We do not limit BANDWIDTH, and you can have up to 1Gbit line for your machine, all RESOURCES are dedicated, so you can be sure, that no matter what size of machines are in the cloud they do not take your virtual machine performance.
Also, the uptime and failover features are more combined together, which means that if any HDD will crash your machine will be online. Hope I have explained you much of it.
So, it does not matter what machine you have or what machines are in the cloud the performance stays the same. This solution is the same as Amazon cloud, but they do not give IP addresses as much as you want (as we do), the prices are sky high (charged per hour, as we charge month, no matter how you use your machine).
