Cloud Server Hosting offers REAL Cloud Servers, not a simple VPS. What is the difference? A VPS is only a virtual machine running on a physical machine; whereas a cloud server is a highly available cloud server instance running on a highly available, fully redundant cluster of servers and SAN components. All cloud servers are instantly on-demand, scalable and highly available. Choose from Windows Server 2012, 2008 R2 Web/Standard/Enterprise editions or CentOS.
