Shared Server Hosting - Brief Overview
A shared web hosting service or virtual hosting service or derive host refers to a web hosting service where many websites reside on one web server connected to the Internet. Each site "sits" on its own partition, or section/place on the server, to keep it separate from other sites. This is generally the most economical option for hosting, as many people share the overall cost of server maintenance.
The hosting service must include system administration since it is shared by many users; this is a benefit for users who do not want to deal with it, but a hindrance to power users who want more control. In general shared hosting will be inappropriate for users who require extensive software development outside what the hosting provider supports. Almost all applications intended to be on a standard web server work fine with a shared web hosting service. But on the other hand, shared hosting is cheaper than other types of hosting such as dedicated server hosting. Shared hosting usually has usage limits and hosting providers should have extensive reliability features in place.
Shared hosting typically uses a web-based control panel system, such as cPanel, DirectAdmin, Plesk, InterWorx, H-Sphere or one of many other control panel products. Most of the large hosting companies use their own custom developed control panel. Control panels and web interfaces can cause controversy however, since web hosting companies sometimes sell the right to use their control panel system to others. Attempting to recreate the functionality of a specific control panel is common, which leads to many lawsuits over patent infringement.
In shared hosting, the provider is generally responsible for managing servers, installing server software, security updates, technical support, and other aspects of the service. Most servers are based on the Linux operating system and LAMP (software bundle), which is driven by the reliability and security of open source software such as Linux and Apache (the 'L' and 'A' of LAMP). Some providers offer Microsoft Windows-based or FreeBSD-based solutions. For example, the Plesk control panel is available for two operating systems, Linux and Windows. Server-side facilities for either OS have similar functionality (for example: MySQL (database) and many server-side programming languages (such as the widely used PHP web programming language) under Linux, or the proprietary SQL Server (database) and ASP.NET programming language under Windows).
There are thousands of shared hosting providers in the United States alone. They range from mom-and-pop shops and small design firms to mufti-million-dollar providers with hundreds of thousands of customers. A large portion of the shared web hosting market is driven through pay per click (PPC) advertising or Affiliate programs.
Shared web hosting can also be done privately by sharing the cost of running a server in a collocation center; this is called cooperative hosting.
Understanding DNS and Name Servers
DNS stands for "Domain Name Server." The domain name server acts like a large telephone directory and in that it's the master database, which associates a domain name such as (http://www.mydomain.com) with the appropriate IP number. Consider the IP number something similar to a phone number: When someone calls http://www.mydomain.com, your ISP looks at the DNS server, and asks "how do I contact http://www.mydomain.com '?" The DNS server responds, for example, it can be found at: 216.198.221.66. As the Internet understands it, this can be considered the phone number for the server, which houses the http://www.mydomain.com web site. When you register/purchase your domain name on a particular "registrars name server", your DNS settings are kept on their server, and in most cases point your domain to the Name Server of your hosting provider. This Name Server is where the IP number (currently associated with your domain name) resides.
