Shared hosting, sometimes known as shared services or virtual hosting, is simply when multiple websites share exactly the same server, thus lowering the cost for everybody.
Having a shared hosting account, your site will often be on the server with hundreds of other websites. That could seem like a lot, however it usually works out very mainly well because most sites do not generate enough traffic or use enough resources for this to become a problem.
Would you like web hosting at a low cost? Then shared hosting is the one thing for you. While you share server with other people the companies can offer its clients very affordable prices. The hosting that is shared segment is definitely a very competitive one, meaning it may be hard to select a provider.
Let us dig more deeply the things behind shared hosting. The shared web hosting service is shared by many people customers and should include system administration. This is really advantageous to customers that do not want to cope with it, but an impediment to energy customers that are looking with additional control.
Shared hosting normally utilizes a web-based control panel system, for example cPanel, DirectAdmin, Plesk, Sphera, Ensim, Helm, H-sphere, or one of several other control panel items. Control panels and web interfaces have been involved in a intriguing debate as Web.com claims that it holds patent privileges towards the hosting technology with its 19 patents.
A sizable wholesale host named Hostopia, lately bought a license to make use of that technology from web.com for ten percent of retail revenues. Web.com lately prosecuted Godaddy too for similar patent violation.
The hosting provider for shared Linux hosting accounts handles setting up of server software, management of servers, security updates together with other available choices that include the assistance. Servers are often based on Linux operating systems because with additional Control Panel products are produced for Linux. Though, some companies offer Microsoft Windows or FreeBSD based solutions. The Plesk control panel, for instance, has two versions – for Linux and Windows, both with very alike interfaces and functionality, with the exception of OS-specific differences (for example, supporting ASP.NET, or Microsoft SQL Server on Windows).
There are numerous shared hosting providers in the United States alone. They vary from home shops, to small design firms, to multi-million dollar companies with hundreds of thousands of clients.
An excellent area of the shared hosting company market is driven through Pay Per Click advertising (PPC) or affiliate marketing programs. Shared hosting can also be done independently by discussing and sharing the cost of managing a server, this is known as cooperative hosting.
Implementation of shared hosting can be accomplished in two ways: IP-based and name-based. IP-based – In IP-based shared web hosting, also called dedicated IP hosting, each virtual web host has a unique IP address. The web server software is set up with multiple physical network interfaces, or virtual network interfaces on a single physical interface. The web server software uses the IP address the customer connects to in order to pick which web site to show the user. Name-based – In name-based virtual hosting, also known as shared IP hosting, the virtual hosts serve multiple hostnames on one machine having a single IP address.
Whenever a web browser demands an origin from the web server using HTTP/1.1 it includes the asked hostname included in the request. The server uses these details to find out which web site to show the user.
On the other hand, name-based shared hosting has some disadvantages. First, they do not correctly support secure websites (HTTPS). All name-based virtual hosts utilizing the same IP must share exactly the same digital certificate. The reason is being the SSL/TLS handshake happens prior to the hostname is distributed towards the server. Thus the server does not know which encryption key to use once the connection is created. An extension to the TLS protocol, a part of RFC 3546 – Transport Layer Security (TLS) Extensions, identifies a means for that client to supply the asked hostname included in the handshake, but it is not broadly implemented. Second, if the Domain Name System is malfunctioning, it is harder to use a name-based virtually-hosted website. Typically, in this case, the user could fall back to using the IP address to contact the system, as in http://127.0.0.1/ (invalid IP for example only). However, the web browser doesn’t know what hostname to send to the server, but a name-based virtual host requires it. Lastly, they will not function with browsers that do not send the hostname as part of requests. This is true for older HTTP/1.0 browsers that have not retrofitted the host field feature from the HTTP/1.1 protocol.
