Vps Web Hosting

Shared hosting allows thousands of​ people to​ host their own sites at​ a​ very reasonable cost. it​ has some drawbacks, however. Since hundreds of​ sites can be hosted on a​ single server resources such as​ CPU, disk space, and​ bandwidth have to​ be shared with your virtual neighbours.

Shared resources are usually not a​ problem for​ small to​ medium sized sites. Your main limitation is​ the​ lack of​ control over system level software – http servers, mail servers etc. You don't have any choice of​ operating system and​ you cannot compile programs or​ do administrative tasks such as​ setting up Spam filters or​ firewalls.

Many people would say 'So what? I don't want to​ do that stuff anyway!' It's true that the​ majority of​ website owners have no interest or​ ability to​ handle this kind of​ work and​ are happy to​ leave it​ to​ the​ hosting company. Those who desire more control over their server environment or​ wish to​ experiment with new software, however, can get access to​ this level of​ management with a​ Virtual Private Server.

A virtual private server (VPS) is​ a​ physical server that has been divided (using software) into several virtual machines, each acting as​ an​ independent dedicated server. the​ physical resources such as​ RAM, CPU and​ disk space are still shared, but each VPS acts independently of​ the​ others. Each VPS can have a​ different operating system and​ can be configured in​ any way possible.

The key advantage of​ VPS is​ allowing each VPS administrator access to​ the​ root level of​ his virtual server. This kind of​ access allows the​ administrator to​ install and​ delete software, set permissions, create accounts – in​ short, do everything that the​ administrator of​ a​ 'real' sever can.

As well as​ providing more control over your hosting environment, a​ VPS is​ more secure than shared hosting. Websites on a​ shared server all have the​ same operating system, so if​ a​ hacker were to​ find access to​ the​ root of​ the​ server he could damage any or​ all of​ the​ websites on that server. a​ VPS, on the​ other hand, is​ divided in​ such a​ way that even if​ a​ hacker were to​ gain entry through one account, there is​ no way to​ access the​ others. Each VPS is​ invisible to​ the​ others and​ there is​ no way to​ set up root level access from one VPS to​ another.

Virtual Private Servers can be set up in​ various ways so be sure to​ understand how the​ hosting company has allocated resources. the​ most common configuration is​ to​ divide all the​ physical resources evenly by the​ number of​ accounts. Thus, if​ there are 10 virtual servers, each would receive 10% of​ the​ total bandwidth, CPU, memory and​ disk space.

The disadvantages of​ VPS are almost the​ same as​ the​ advantages. the​ control that a​ VPS account provides can be dangerous if​ you don't know what you are doing. You have the​ ability to​ delete files, set permissions improperly, allow virus-laden software on the​ system and, in​ general, really screw things up. if​ you don't have the​ knowledge to​ administer a​ server, or​ are not willing to​ learn, VPS is​ not for​ you.

If your website has outgrown shared hosting, however, VPS offers an​ affordable alternative to​ dedicated hosting. When shopping for​ a​ VPS host, be sure to​ find out how system resources are divided up, the​ number of​ VPS accounts on each physical server, the​ method for​ upgrading, and​ the​ choices of​ operating systems.
