What is the difference between Cloud servers and VPS servers?
We offer two types of virtual servers; Cloud Virtual Datacenters (Cloud VDC) and Standard VPS plans. We will go over a brief synopsis of each below, and then the differences afterward.
Cloud Virtual Datacenters (Cloud VDC/Cloud VPS)
Our Clouds are essentially just a pool of resources. Using these resources you will provision Virtual Machines (VMs) inside your cloud. Clouds can host single VMs, or multiple -- they are very flexible.
Standard VPS servers
The standard VPS servers are a single server instance. These are very similar to the Virtual Machines that you would provision inside your Cloud with a Cloud Virtual Datacenter
So, what's the difference between a Cloud and a VPS?
1) Storage Method
The virtual servers inside a Cloud VDC use redundant SANs (Storage Area Network) to store the virtual machine's data. The SANs are large disk appliances that are not physically attached to the host node that the virtual machine is on. What this does is allow for your VM to be booted on a spare hardware node in the event that the host node goes offline. In short, higher availability for the server.
The Standard VPS plans use local disks, much like a standard desktop computer, so in the event that one of those host nodes goes offline the data cannot be retrieved to boot your server up on a spare node.
2) Resource Customization
Another main difference is that the Cloud systems are incredibly customizable. You can pick your resources A'la Carte, in millions of different configurations. This flexibility, combined with the ability to host multiple VMs inside one cloud tends to be more economic, and easier to manage. The Standard VPS plans have far fewer customizations available and in almost all cases you would need to upgrade the entire plan level in order to increase a single resource
3) Operating System Availability
Lastly, the Clouds can host both Windows and Linux virtual machines, but the Standard VPS plans are only available in Linux. If you need Windows the Clouds are the only choice.
