VPS stands for Virtual Private Server. The Virtual Private Server or Virtual Dedicated Server (VDS) hosting is one of the forms of web hosting that has recently gained popularity. In VPS hosting, the physical server in the data center is divided or partitioned into multiple virtual servers or spaces where resources can be allocated in a way that does not directly reflect the underlying hardware.
Data is stored on a virtual server in the form of a virtual machine (VM), and this VM works just like the server you may have located. You can have multiple VMs on a single server, or you may share your server with the data from other companies without interacting with each other, despite the fact that they share the same server where only you have the proper permission to access it.
With a VPS, you can have access to a far greater amount of space as well as to multiple VMs, if you want to host each web site using a different operating system or give each one with different permission. With VPS hosting, your information and data are absolutely secure, and you enjoy a level of isolation or independence. Unlike the shared hosting services, the other websites on a same server are not affected with a troubled neighboring website and significantly; most of the functions on a virtual private server are in the hands of the user not the hosting company. Of course, the maintenance for the virtual private server will lie in the hands of the VPS hosting company allowing you to focus on your websites rather than worrying about upgrades, patches, and repairs.
