Virtual Private Servers or VPS technology allows website proprietors to share the costs of a dedicated web server with other users. It also gives the website owner total control over the applications installed and run on the web server.
Several virtual private servers can run as isolated processes within an internet server and provide dedicated root access and complete privacy to unmetered VPS hosting accounts, as well as guaranteed bandwidth, CPU resources, disk space, storage, and the like.
Unmetered VPS hosting offers a perfect blend and balance between regular shared hosting and dedicated server hosting. A VPS is a single hardware node split into multiple digital machines (known as VPS or VDS). Virtualization technology, either Xen or OpenVZ, fully separates each of these VPS / VDS / VMs from each other. This means each VPS is provisioned with a guaranteed set of resources (CPU, Ram memory and Hard Drive space) and that all VPS comes with full root access.
Traditionally guaranteed resources and root access were originally only available with full dedicated servers but, today, virtualization technology now allows dedicated server hosting companies to offer very competitively priced Virtual Private Servers that cost less than a dedicated server.
VPS infrastructure is much sought after by many companies as compared to dedicated servers. Each hardware node is a Supermicro or Dell organization class server featuring 16 Intel XEON CPU/Processors, 32GB DDR3 ECC Memory and 4 or 8 RAID10 hard drives. Of course, hardware for any VPS has to be this heavy if it is to serve its function as a hosting server with a specialization.
VPS actually has features of both shared and dedicated hosting but, removes the limitations of both types of hosting. It uses special software that takes an one physical web server and divides it into 2 or more separate virtual web servers. Each digital server functions as if it is a totally individual machine. The main large server is partitioned and leased out to different users, thus giving them their own os’s and main access to these partitions. The gain access to provides the users with great technical control and ability to revise, install or change system software needed and to execute root user operations.
