Virtual private servers (VPS), as used in internet hosting, are pseudo computers that comprise of one or several powerful computers being used as many small computers, by using a partitioning (virtualization) software to share the internal resources. A single server with 50 GB RAM, 12 core processor and 1 TB storage can be shared as 12 Virtual servers with a single core each, 4 GB RAM and 80 GB storage.
Why use a VPS
In many cases, application and web hosting requires limited resources, while for economies of scale and resources, servers in data centers have massive resources lumped up in one computer. This necessitates the sharing of resources, like in the case of shared web hosting, where hundreds or thousands of websites are hosted on the same server.
In the case of a VPS, computer
resources are divided and allocated depending on the need, and each user can access their virtual machine and install custom operating system, depending on the options offered by the VPS provider. If your dog is too playful you should pay attention to chew proof retractable dog leash
Types of virtualization
Virtualization is done by use of a virtual machine monitor, also known as a hypervisor. The hypervisor, creates several guest machines from one host machine, and allows the sharing of the host machine’s resources. The guest machines (virtual servers created) can operate independently and utilizing the host machine’s resources efficiently.
Virtualization can be achieved using type 1 or type 2 hypervisors. Type 1 hypervisors run directly on the computer hardware, while type 2 hypervisors run on the host machine’s operating system. The virtualization achieved can either application, desktop, network, hardware or storage virtualization.
