Most VPS hosts only offer servers running Linux-based operating systems; you'll need to dig a bit to find Windows-based VPS hosting. This is important to note if you're planning on running software that requires a Microsoft-compatible environment. That said, Linux-based VPS hosting will save you a few bucks; Linux servers usually cost $10 to $20 less than Windows servers.
It’s recommended that you do not statically assign the private IP assigned to the Azure virtual machine within the operating system of a VM, unless necessary, such as when assigning multiple IP addresses to a Windows VM. If you do manually set the private IP address within the operating system, ensure that it is the same address as the private IP address assigned to the Azure network interface, or you can lose connectivity to the virtual machine. Learn more about private IP address settings. You should never manually assign the public IP address assigned to an Azure virtual machine within the virtual machine's operating system.
However another option is to pool together a cluster of physical servers into a cloud arrangement whereby the data is stored across several physical disks in several physical machines. This dramatically reduces the possibility of hardware related downtime by spreading the load and the risk of hardware failure. This is a High Availability Cloud setup which Pickaweb uses.
Virtual Private Server (VPS) hosting definitely seems to be the future of the web hosting world. An unmanaged VPS hosting service is a solution that is completely under the control of the customer. Web hosting providers do not recommend such a service to people who don't know how to establish, manage, and function a web server; in such a case, managed VPS hosting provides a better solution.
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
