Web hosting is a service that provides individuals, organizations and users with online systems for storing information, images, video, or any content accessible via the Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center.
The scopes of hosting services vary widely. The most basic is file hosting (or Web page hosting), where Web pages and other files can be uploaded via FTP or a Web interface. The files are usually delivered to the Web "as is" or with little processing. Many ISPs offer this service for free to its subscribers. People can also obtain Web page hosting from services such as GeoCities or Yahoo!. Web page hosting is typically free, advertisement sponsored, or cheap.
Web page hosting is typically sufficient only for personal home pages. A complex site calls for a more comprehensive package that provide database support and application development platforms (e.g. PHP, Java, and ASP.NET). These facilities allow the customers to write or install scripts for applications like forums and content management. For e-commerce, SSL is also required. The host may also provide a Web interface (e.g. cPanel) for managing the Web server and installing scripts as well as other services like e-mail.
Some hosts specialize in certain software or services (e.g. e-commerce). They are commonly used by larger companies to outsource network infrastructure to a hosting company.
Hosting can be split up into several general types:
Web hosting is often provided as part of a general Internet access plan; there are many free and paid providers offering these services. The free services generally have restrictions on how the space can be used, including but not limited to: advertising, bandwidth restrictions, and programs that can be used to edit sites.
Businesses are generally restricted to using a paid Web host to host their site on. Paid Web hosts usually provide many more features, including 24/7 support and personalized assistance. Sites hosted on paid Web hosts also tend to load more quickly since each server hosts fewer sites, giving each site a larger proportion of resources.
A customer also needs to evaluate the requirements of the application. Such considerations include database server software, scripting software, and operating system. Active Server Pages (ASP) web sites usually require a Microsoft Windows based server platform. Most hosting providers provide Linux-based web hosting which offers a wide range of different software. A typical configuration for a Linux server is the LAMP Platform. This includes Linux, Apache, MySQL, and PHP (or Python, Perl or Ruby). Usually there is limited interoperability between the two, although Linux servers can integrate with Windows file services through Samba, and many Linux hosts provide support for Microsoft FrontPage server extensions.
Regardless of whether one is a business or has a personal site that needs to be hosted, it has to be created first. HTML experience is usually required to create a site (and more advanced languages can be used for interactive content, such as ASP or those languages used in a LAMP setup), but those without design experience can hire a Web designer to do the heavy lifting. Once the site is online there's not much else that's required: the host generally handles the technical behind-the-scenes work with the server.
Recently, web hosting packages often include a Web Content Management System, so the end-user doesn't have to worry about the more technical aspects. There exist a growing number of Typo3- or Mambo-Hosters. Other popular content management systems include PHP-Nuke and e107.
The World Wide Web is a massive collection of web sites, all hosted on computers (called web servers) all over the world. The web server (computer) where your web site's html files, graphics, etc. reside is known as the web host. Web hosting clients simply upload their web sites to a shared (or dedicated) webserver, which the ISP maintains to ensure a constant, fast connection to the Internet.
Providing space on Internet servers for the storage of World Wide Web sites which can be accessed by others through the network. This service is usually offered by ISPs or web hosting specialists.

If you are making a comfortable living from the Internet and the Web or have a plan to achieve that goal, it's likely that you are running more than ten websites. The websites are your virtual offices. You want to your sites to be up and running 365 days, 7 days a week and 24 hours a day. Managing multiple websites is a daunting task if running one website is a hobby.
Proposed Hosting Strategy for Managing Multiple Websites
The hosting strategy we propose is to host your multiple major websites with 3-4 different hosting companies, and open a reseller account with another hosting company for 1) small and new websites, 2) web development and 3) backup. Hosting with too many hosting companies will significantly increase the time and the difficulty of managing sites, and using a single hosting company isn't a smart choice either.
Justification of the Hosting Strategy
Cost - Cost of the Web hosting isn't an issue for running a single web site whether it costs $5 or $25 a month. The difference is only a few hundred dollars or less a year. It's always nice and smart to get the most out of every single dollar in doing business. At least, a few hundred dollars difference wouldn't make or break a business. If you run 10 or even 50 websites, the cost of Web hosting alone will define the success or failure of your online adventure. To cut the hosting cost, the option is to use a reseller hosting account to host as many small or new sites as you want for about $15 a month. You host one or 2 major websites with one hosting company. Shared hosting account costs under $10 a month, and dedicated server will cost $50 or more a month.
Uptime - If your bread-and-butter maker website is down for a few hours, you'll lose hundreds of dollars and more. Even though most hosting companies promise 99.9% uptime, it's not common to see a website down for a few hours. A site could be down for a half day or even more if a hosting company is doing a major update. The hosting company may do the update in a weekend or a major holiday, but that's when many family-oriented and travel sites generate their revenues. If you could afford the loss of revenues, many websites owners can't bear the psychological loss and pressure. Hosting your sites with a few hosting companies will reduce the risk of downtime.
Application Development - For simple web application, webmasters will do development on the same production hosting site. If your ecommerce applications are complex, doing development on the production site may bring down the live site especially if you're in the process of changing configuration files or install customized applications. The option is setup a website on your reseller account for development and testing, and move the applications to production account on another server after the completion.
Backup - If you're not happy with a hosting company, a hosting company is out of business, or the servers will be down for a day or two, you can easily temporarily or permanently switch from one hosting company to other since you're familiar with the site managing tools already. If you have a backup or secondary copy running on another server, all you need for the switch is the transfer of the domain, which will take no more than a minute.

Before you start searching for a web host, you must familiarize yourself with the terminology used in this field. The following terms are also considered key factors in deciding the suitable hosting plan that meets your requirements. You can start learning what does each term mean and how does it affect your selection.
Web Host
A web host, also known as web server, is a computer connected to the internet. This computer is more powerful than normal PCs and is set up to serve up websites. Your website content will reside on this computer, which will give people who surf the internet a way to access your website.
Web hosts can be categorized into three main categories based on the price range and common features for each category:
1. Free Hosts: limited in space, bandwidth and other features. Suitable for personal websites or for temporary usage. Usually enforce pop-up, text or banner ads. They do not provide the best performance and/or reliability. They provide minimum or no customer support. If you register for a free host, your domain will be something like yourname.freehost.com or www.freehost.com/yourname.
2. Shared Hosts: most websites are using this type of hosting. Suitable for personal, small and medium businesses. Prices range from $1 to about $25 a month. Features also range from very limited space/bandwidth to semi-dedicated servers. Your website has its own top level domain (e.g. www.website-hostings.net) The number of websites on a server affects its performance and availability, more websites usually means less performance. Servers hosting less number of shared websites are more expensive, but more reliable. Some companies allow customers to host multiple websites with different domains under a single account.
3. Dedicated Hosts: A full server dedicated to a single customer. Usually used by large businesses and very active websites with thousands of daily visitors. The customer will have full control over the server, and can create as many websites as he likes. Customer can have his own hosting company run on a rented dedicated server. Prices depend on the specifications and services provided with the server, starting from about $100 up to about $800 dollars a month.
4. Colocated Hosts: very similar to dedicated hosts, but the customer owns the server hardware instead of renting it. The server will be housed in provider's data center. Prices are a bit higher than dedicated servers.
5. Reseller Hosts: providers offer web server storage to customers, who then resell the web server storage to their customers. Providers usually offer resellers a discount price.
6. Other Hosts: there are few other types of hosts such as email hosts, media hosts, data hosts, etc but these are out of the scope of this article.
Domain Name
www.website-hostings.net is an example of a domain name. It's a name that points to where your website is physically located. The actual address of your website is a set of numbers that looks like (70.86.135.242). This address is unique for every web server. Domain names are just pointers to the real addresses. It's easier to remember the domain names than the IP addresses.
Space / Storage
The amount of web server's disk space available for customer's website files, images and databases. It can be as small as 5MB in some free hosts and as big as 300GB for some dedicated servers. Space prices reduced significantly during the last few years. Customer can find hosting plans offering 3GB of space for less than $10 a month.
Bandwidth
Bandwidth is the amount of data transferred from web server to clients' internet browsers. Each time a person view a page data is transmitted from the server to that person's PC. Audio, video and images contents consume much more bandwidth than text. Bandwidth can be as low as 100MB a month in some free web hosts and as high as 2000GB a month in some dedicated servers. Customer can find hosting plans offering 75GB of monthly data transfer for less than $10.
Server Type
Usually means the operating system than runs the web server. Common types are Windows, Linux and UNIX. Server type determines the server side scripting and database types. Windows usually runs ASP and ASP.NET with Access or SQL Server databases. Linux/UNIX servers usually runs CGI, PHP or JSP with mySQL or Oracle databases. Windows servers are usually more expensive than Linux/UNIX servers.
Databases
As you have seen in server types, there are different types of databases. The most commonly used is mySQL because its an open source GPL (free) software and can serve a lot of online applications' requirements such as forums, content management, mailing lists, etc. MySQL, however, has some limitations in its features. Complicated large business sites will need more powerful databases such as Oracle or SQL Server.
Server Side Scripting
Most new users prefer to use PHP as server side scripting. The reason is that there are hundreds of open source (GPL) PHP scripts that can meet a lot of webmaster's requirements. Similar to mySQL, PHP has some limitations in features required by advanced websites, which makes some senior web developers prefer to use ASP.NET or JSP. Other developers still prefer to use Cold Fusion, CGI, ASP or PERL.
Email
Most hosting plans include the feature of having some email accounts with customer's domain (e.g. admin@website-hostings.net). The number and size of email accounts depends on the hosting plan. Free plans do not usually have this feature, small plans give about 10 accounts where big plans do not limited the number. Those email accounts are usually web based and accessible through POP3 clients as well.
File Transfer Protocol (FTP)
A standard way of transferring files across the Internet. Most webmasters upload and download their websites contents using FTP. The upload or download processes are usually performed using FTP client software. To access their web servers, webmasters need FTP username and password. Some hosts give more than one FTP account to their customers. FTP can by anonymous as well, but its not recommended for security reasons.
Control Panel
Most web hosting companies provide their customers with a control panel, a web based application that helps in managing websites. Common functions in control panels are: managing email accounts, providing statistics, managing FTP accounts, managing domains and subdomains and managing databases. The most commonly used control panel application is cPanel. Some companies develop their own control panel application.
Uptime
An important feature of web hosts is their uptime, which is usually measured in percentage. A server that goes down for an average of 30 minutes a day will have an uptime percentage of about 99.98%, which is acceptable for most small to medium business websites. Anything less than this percentage is not suitable for a business website. Mission critical sites cannot tolerate frequent outages, thus they may use web monitoring services to notify web administrators immediately when an outage happens.
Price
With the wide range of options available for customers, the price is also ranges from 0 to $1000 a month. Most personal, small and medium websites shouldn't cost more than $15 a month. It's not recommended for business website owners to go for very cheap plans (less than $5) because this price usually means a compromise in the quality of support and reliability of the server.
