VPS Hosting is short for Virtual Private Server. What this means means is a physical server (host machine) is virtualized into a few smaller virtual servers, ie, a VPS.
We purchase extremely powerful servers and load them with Ram. This allows us to make sure your VPS has full access to the resources of the plan, meaning we do not over-sell the host server capacity. Additionally, our host servers are in a highly available environment so that your VPS will be automatically brought up on a different host server should the host server fail that it is running on.
