The web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on servers owned or rented for use by clients, as well as providing Internet connectivity, typically in data centers. Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.

History
Until 1991, the internet was limited to just using ... for research and education in science and engineering... and used for email, telnet, FTP and USENET traffic - but only a small number of web pages. The World Wide Web Protocol was just written and not until the end of 1993 there will be a graphical web browser for Mac or Windows computers. Even after there were several internet access openings, the situation was confusing until 1995.
To host websites on the internet, individuals or companies will need their own computer or server. Since not all companies have the budget or the expertise to do this, the web hosting service starts offering to host the user's website on their own server, without the clients needing to have the necessary infrastructure to operate the website. The website owner, also called the webmaster will be able to create a website that will be hosted on the web hosting service server and published to the web by the web hosting service.
As the number of users on the World Wide Web increases, the pressure for companies, both large and small to have an increased online presence. In 1995, companies like GeoCities, Angelfire and Tripod offered free hosting.

Hosting type
An internet hosting service can run a Web server. The scope of web hosting services vary greatly.
Smaller hosting services
The most basic is the web page and the hosting of small files, where files can be uploaded via File Transfer Protocol (FTP) or Web interface. Files are usually sent to the Web "as is" or with minimal processing. Many Internet service providers (ISPs) offer this service for free to customers. Individuals and organizations can also obtain web page hosting from alternative service providers.
Free web hosting services offered by different companies with limited services, sometimes supported by advertising, and often limited when compared to paid hosting.
One page hosting is generally enough for a personal web page. Private hosting websites are usually free, sponsored ads, or inexpensive. Website hosting businesses often have higher costs depending on the size and type of site.
Larger hosting services
Many large companies that are not Internet service providers need to be permanently connected to the web to send email, files, etc. To another site. Companies can use the computer as a website host to provide details of their goods and services and facilities for online orders.
Some special hosting types provided by the web host service provider:
- File hosting service: host file, not web page
- Image hosting services
- The video hosting service
- The blog hosting service
- Paste bin
- Shopping cart software
- The e-mail hosting service
Host management
The host can also provide an interface or control panel for managing Web servers and installing scripts, as well as other service modules and applications such as e-mail. Web servers that do not use the control panel to manage hosting accounts are often referred to as "headless" servers. Some hosts specialize in specific software or services (e.g. e-commerce, blogs, etc.).
Reliability and active time
Website availability is measured by a percentage of a year in which websites are publicly accessible and reachable via the Internet. This is different from measuring the uptime of a system. Uptime refers to the system itself is online. Uptime does not account for being able to achieve it as in the event of a network outage. Service Level Agreement The hosting provider (SLA) service may include a fixed number of scheduled stops per year to perform system maintenance. These scheduled stops are often excluded from the SLA period, and need to be deducted from Total Time when availability is calculated. Depending on the SLA rendering, if system availability falls below the one in the signed SLA, the hosting provider will often provide a partial refund of lost time. How the downtime is determined changes from provider to provider, therefore reading SLA is very important. Not all providers release working time statistics. Most hosting providers will guarantee at least 99.9% operating time that will allow 43m downtime per month, or 8 hours 45m downtime per year.
Getting hosting
Web hosting is often provided as part of a common Internet access plan from an Internet service provider. There are also many free and paid providers that offer web hosting.
A customer needs to evaluate the application requirements to select the type of hosting to be used. These considerations include database server software, scripting software, and operating systems. Most hosting providers provide Linux-based web hosting that offers a whole range of different software. The typical configuration for Linux servers is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. Web hosting clients may want to have other services, such as email for their business domain, database or multimedia services. A customer can also choose Windows as a hosting platform. Customers can still choose from Perl, PHP, Python, and Ruby, but can also use ASP.Net or Classic ASP. Web hosting packages often include Web Content Management Systems, so end users do not have to worry about more technical aspects.
Security
Because web hosting services host their customers' websites, online security is an important issue. When a customer agrees to use a web hosting service, they release control of the security of their site to the company hosting the site. The level of security offered by web hosting services is very important to potential customers and can be a key consideration when considering which providers a customer can choose from.
Web hosting servers may be attacked by malicious users in different ways, including uploading malware or malicious code to a hosted website. These attacks can be done for different reasons, including stealing credit card data, launching a Distributed Disclaimer of Service (DDoS) or spam.
