-a [shared web hosting service] is a [web hosting service] where many [websites] reside on 1 [web server] connected to the [internet]-
.
the overall cost of server maintenance is spread over many customers
By using shared hosting, the website will share a physical server with one or more other websites
.
Description
Shared web hosting services 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)
Some providers offer Microsoft Windows-based or FreeBSD-based solutions.
Server-side facilities for either operating system (OS) have similar functionality (for example: MySQL (database) and many server-side programming languages (such as the widely used PHP programming language) under Linux, or the proprietary SQL Server (database) and ASP.NET programming language under Microsoft Windows.[citation needed]
There are thousands of shared hosting providers in the world
They range from “mom-and-pop shops” and small design firms to multimillion-dollar providers with hundreds of thousands of customers.
Shared web hosting can also be done privately by sharing the cost of running a server in a colocation center; this is called cooperative hosting
.
Implementation
Shared web hosting can be accomplished in two ways: name-based and Internet Protocol-based (IP-based), although some control panels allow a mix of name-based and IP-based on the one server.
IP-based[edit]
In IP-based virtual hosting, also called dedicated IP hosting, each virtual host has a different IP address. The web server is configured with multiple physical network interfaces or virtual network interfaces on the same physical interface. The web server software uses the IP address the client connects to in order to determine which website to show the user.
Name-based[edit]
In name-based virtual hosting, also called shared IP hosting, the virtual hosts serve multiple hostnames on a single machine with a single IP address. This is possible because when a web browser requests a resource from a web server using HTTP/1.1 it includes the requested hostname as part of the request. The server uses this information to determine which website to show the user.
DNS and name servers[edit]
Showing how name servers are connected
DNS stands for “Domain Name System”. The domain name system acts like a large telephone directory and within is the master database, which associates a domain name such as www.wikipedia.org with the appropriate IP number. Consider the IP number something similar to a phone number: When someone calls www.wikipedia.org, the ISP looks at the DNS server, and asks “how do I contact www.wikipedia.org?” The DNS server responds, for example, “it can be found at: 91.198.174.192.”. As the Internet understands it, this can be considered the phone number for the server that houses the website. When the domain name is registered/purchased on a particular registrar’s “name server”, the DNS settings are kept on their server, and in most cases point the domain to the name server of the hosting provider. This name server is where the IP number (currently associated with the domain name) resides.
