Virtual Private Server
VPS - Virtual Private Server, is essentially, mimics the dedicated server. The only difference between a virtual server and a dedicated server is that the virtual server is located in a shared environment that hosted on a dedicated server. In other words, on a single dedicated server, can be stored a large number of virtual servers.
Virtual server, who needs it?
Setting up a website is not just the coding. After the programming work is ended, the files must be uploaded to a server that connected to the World Wide Web - the internet. Virtual server (VPS) is one of several types of web hosting accounts, which allow you to store your website. Installation and management of this type of server is not simple at all, One can also say, complicated, but because you can host a large number of websites on the same server, it makes your work much easier, and saves you the need to learn how to set up and maintain a Web server, and of course, saves you a substantial amount of money. All you need to do is just upload your website files to the virtual server.
Types of storage accounts:
1. Shared Hosting
2. VPS Hosting - virtual hosting server
3. Dedicated Server Hosting
The common of those three accounts types is that they all, eventually, provide you infrastructure - a Web server on which to run sites on the Internet.
When you address to a websites hosting provider, in order to upload your new site or transfer your old site, you should prepare in advance, number of details to ease the process:
Check how much disk space you need by weighing your website files.
Do you have a preference for the server operating system (platform)?
Is your website need a Database? and if so, what kind? (MySql, MSSql)
How much capacity you need for the database? Make sure to ask whether it's part of the total volume of the package, or assigned its own volume.
How VPS is working?
The technology behind VPS hosting is similar to VMware or Virtual Box. These programs allow you to run multiple operating systems on a single virtual machine (server).
For example, your pc's os can be Windows 7, but you can also run other operating systems such as Windows XP or Linux, without having to restart the computer. That is the idea behind a virtual server - although we have one physical server, but it can run several different operating systems at the same time, each one of them behaves as if it were a installed on a dedicated server and provides you all the benefits of a dedicated server.
Login to the virtual server is done via remote control software (RDP), and can be operated from any computer connected to the Internet.
In conclusion, a virtual server is acts as a home computer in any aspect, but usually is placed on a data center.
