What is VPS?
VPS is an abbreviation for ‘Virtual Private Server’ which literally means ‘virtual private (dedicated) server’. Most readers are probably acquainted with the notion of a physical server. But those who hear it for the first time should focus their attention on their CPU (if , of course, it’s not a laptop or a table that you use) because this is the physical server itself. The difference is that the majority of people use it only for games, music and movies. But if you install necessary server programs, you will be able to proudly call you CPU a Physical Server.
There are certain peculiarities which distinguish a VPS from a physical server; the main one being a possibility to create an almost unlimited amount of virtual -VPS servers- on the basis of a single physical server. What is more, every VPS server is going to have its own disc space, a portion of the CPU and operative memory. One can reboot, switch on and off their VPS server without influencing other VPS owners.
One more characteristiс feature of using VPS servers is that you can increase or decrease the amount of the resources you need at any moment you wish. Which is why a VPS is convenient for a promo site with a minimal number of visits as well as for a huge portal. In the latter case you can add up a necessary amount of operative memory, increase disc space or CPU frequency in mere seconds.
The price of a VPS is an obvious advantage as well. While a dedicated server is going to cost you about $70, you will be charged about $15 for a cheap VPS.
Also a VPS may serve as a testing area for polishing your skills as a system administrator because:
- you can easily reinstall the system if you have overdone the settings a bit;
- system reinstallation is going to take you just a couple of minutes;
- you can define the server load, and you can either adjust it or find out for sure what parameters your next physical server is going to need.
