A Virtual Private Server is created by partitioning the physical server into multiple mini servers, made possible by the technology of Server Virtualization. The term Virtual Server is widely used by Internet hosting services and it is often used to refer a Virtual Machine. A Virtual Private Server VPS works in a federated environment used by other virtual machines. But in all aspects the functionality is equivalent to that of an environment created by a physical computer dedicated to individual customer needs. It offers the same privacy, which is seen in separate physical computer environment, configured to run server software. Virtual Private Servers are also known with the synonyms Virtual Root Server VRS and Virtual Dedicated Server VDS.
Traffic Handling Users of the server may be hampered by an excessive number of requests from a webpage or application. Your website may become very slow or even temporarily stop. Because this system has its own piece of server capacity that other users can not access, you will not be hampered by other websites or applications. The performance of your website will naturally become a little better and more reliable. The question of being hampered by other websites or applications do not arise at all.
I was running a small private weather website in AWS and the satellite images got "picked up" by a news website and they regularly use them during major weather evenings. AWS' 12c per GB of outbound network traffic made things expensive and VPSServer makes this a lot more manageable and has excellent data volumes included with the price of the VPS. I also get many more CPUs for the price compared to AWS, so I am a happy customer.
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
