Shared Web Hosting Service
You might have heard shared web hosting services by many different names. They are also known as derive hosting and virtual hosting services. They all mean the same thing, which is a web hosting service where many different sites "live" on one server which has been connected to the Internet. Each server is split into pieces, or partitions and the site "sits" on its own partition. This helps to keep your site separate from all the others on the server. Most of the time, this is a very cost effective way of hosting because many different website owners split the cost of server maintenance.
A Basic Description of Shared Hosting
Hosting services of any king have to include system administration. When many website owners share the cost of this, it helps the users who don't want to have to deal with maintaining a whole system, but for those users who want to have their own control; this might not be a good choice. In general, those who need extensive amounts of software development beyond what the host supports might not find that shared hosting services are a good fit for them. Much of the time, any application that works on a web server will do fine when using it on a shared hosting service. Shared hosting is much more cost effective than other kinds of hosting services, including dedicated server hosting. Most of the time, shared hosting will have limits to how much usage a website can have, but the providers generally have solid reliability and features working on their side.
Most shared hosting services choose to use a web based control panel system. A good example of these might include: DirectAdmin, Plesk, cPanel, H-Sphere, InterWorx or one of the other common control panel options. The big hosting companies will probably use a control panel that has been custom developed for them. The problem with many web interfaces and control panels is that many companies will sometimes sell their system rights to other users. Another common problem that can lead to lawsuits for patent infringement is recreating a control panel and all of its functions.
When it comes to shared hosting, providers usually are responsible for all of the server maintenance, updates in software and security, technical support and other general service needs. Servers are commonly based off the Linux operating system and will use the LAMP software bundle. This is often because of the relatively low cost of open source software that is available. Some service providers also offer Microsoft Windows based platforms or FreeBSD solutions. One example is the Plesk control panel, which can be obtained for both Linux and Windows; each version is similar in interface and functionality, except for operating specific differences including ASP.NET, SQL Server and access support for Windows and MySQL for Linux.
Here are thousands of shared hosting providers in the United States alone. They are anywhere from small operations to huge multi-million-dollar services who have hundreds and thousands of website owners. Much of the market is kept operating with the help of affiliate programs and pay-per-click advertising.
Sometimes, shared web hosting is done privately. This happens in the case of cooperative hosting, where the cost of operating a server from a collocation center is shared.
Putting Shared Hosting to Work
Shared web hosting is accomplished in a couple of ways. The first is name based and the second is IP-based. Some control panels work with a combination of name and IP based working on the same server.
Name-based Virtual Hosting
Shared IP hosting is also known as name based virtual hosting. In cases such as this, a virtual host will work with many different hostnames on a single machine with a single IP address.
When a web browser places a request asking for a resource from a web server and uses HTTP/1.1, it is asking for the hostname in the request. A server will take this information and decide which website it needs to show a user.
IP-based Virtual Hosting
When it comes to IP-based virtual hosting, it is also called dedicated IP hosting. Dedicated IP hosting is where every virtual host has an individual IP address. Web servers are made up of different physical network interfaces, or many virtual network interfaces on only one physical interface. Web server software will then get the IP address that a person connects to as a way to determine which site the user needs to see. The primary reason that sites choose to use dedicated IP is so that they don't have the problem of using a shared SSL certificate.
