Cpanel Website Hosting

A website hosting service is a kind of internet hosting service that allows individuals and organizations to make their site accessible via the world wide web. Web hosts are organizations that offer space on a server owned or leased for use by customers, as well as providing internet connectivity, typically in a data center. Website 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

Up till 1991, the internet was restricted to use only "...for research and education in the sciences and engineering..." and was used for email, telnet, FTP and USENET traffic, but only a small number of web pages. The world wide web protocols had only just been written and not until the end of 1993 would there be a graphical web browser for Mac or Windows computers. Even after there was some opening up of internet access, the situation was challenging until 1995.

To host a website on the internet, an individual or business would need their own computer system or server. As not all companies had the money or experience to complete this, web hosting services began to offer to host users' websites on their own servers, without the client needing to configure the necessary infrastructure required to operate the web site. The owners of the sites, also called webmasters, would be able to construct a website that would be hosted on the website hosting service's server and published to the web by the web hosting service.

As the number of users on the internet increased, the pressure for organizations, both big and small, to have an online presence grew. By 1995, organizations such as GeoCities, Angelfire and Tripod were supplying free hosting.

Classification

Smaller Hosting Services

The simplest is aweb page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web site interface. The files are typically delivered to the web "as is" or with minimal processing. A lot of internet service providers (ISPs) offer this service at no charge to users. Individuals and companies may also obtain website page hosting from alternative service providers.

Free website hosting service is supplied by different companies with limited services, generally supported by adds, and at times limited when compared to paid hosting.

Single page hosting is often sufficient for personal website pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting at times has a greater cost depending upon the size and type of the 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 other sites. The company may use the computer as a website host to supply details of their products and services and facilities for online orders.

A complex site needs a more inclusive package that offers database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These options allow clients to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for sites that wish to keep the data transmitted more secure.

Types of Hosting

Internet hosting services can manage web servers. The scope of web hosting services differs a lot.

Shared Web Hosting Service

One's site is placed on the same server as many other sites, ranging from a few websites to hundreds of websites. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this type of service can be quite simple and not flexible in terms of software and updates. Resellers often provide shared web hosting and website organizations generally have reseller accounts to provide hosting for customers.

Reseller Web Hosting

Reseller website hosting permits customers to take on the role of website hosts themselves. Resellers may function, for individual domains, under any combination of these following types of hosting, depending on who they are working with as a reseller. Resellers' accounts may vary quite a bit in size: they may have their own virtual dedicated server to a colocated server. Many resellers offer a nearly identical service to their provider's shared hosting plan and provide the technical support themselves.

Virtual Dedicated Server

This is also known as a Virtual Private Server (VPS), it divides server resources into virtual servers, where resources can be split up in a way that doesn't directly reflect the computer's hardware. VPS will often be allocated resources based on a one server to many VPSs relationship, however, virtualization might be done for a few reasons, which includes the option to move a VPS container from one server to another. The users may have root access to their own virtual space. Clients are sometimes responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may offer server administration tasks for the client (managed server).

Dedicated Hosting Service

The customer gets their own web server and gets absolute control over it (user has root access for Linux/administrator access for Windows); but, the customer sometimes doesn't own the server. One kind of dedicated hosting is self-managed or unmanaged. This is typically the least expensive for dedicated plans. The user has full administrative access to the server, which means the customer is responsible for the security and maintenance of their own dedicated server.

Managed Hosting Service

The user gets their own website server but they are not allowed complete control over the server (the customer is not given root access for Linux/administrator access for Windows); however, they are allowed to control their data via FTP or other remote management software. The customer is not allowed complete control so that the provider can guarantee the quality of service by not allowing the user to modify the server or perhaps create configuration issues. The user usually doesn't own the server. The server is leased to the client.

Colocation Web Hosting Service

Similar to the dedicated web hosting service, but the client owns the colocation server; the hosting company offers physical space that the server takes up and takes care of the computer. This is the strongest and costly type of website hosting service. In most cases, the colocation provider may supply little to no help directly for their customer's machine, providing just the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the customer would have his own administrator visit the data center on-site to do any hardware upgrades or changes. Formerly, a lot of colocation providers would allow any computer configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting organizations now require rack mount enclosures and standard system configurations.

Cloud Hosting

This is a relatively new type of hosting platform that permits users powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website may be more stable than others as other servers in the cloud can take over when a single piece of hardware stops working. Furthermore, local power disruptions or even natural disasters are less of a problem for cloud hosted websites, as cloud hosting is not centralized. Cloud hosting also permits providers to bill users only for resources used by the user, rather than a flat rate for the amount the client expects they might consume, or a fixed amount upfront hardware investment. Alternatively, the lack of centralization may give users less control over where their data is located, which could be a problem for customers with data security or privacy worries.

Clustered Hosting

Having multiple servers hosting the same content for stable resource utilization. Clustered servers are a wonderful solution for high-availability dedicated hosting, or customizing a scalable website hosting system. A cluster may separate web serving from database hosting capability. (Often website hosts use clustered hosting for their shared hosting plans, as there are a lot of options to the mass managing of users).

Grid Hosting

This form of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes.

Home Server

Typically, a single server placed in a private home can be used to host one or a few web sites from a generally consumer-grade broadband connection. These can be purpose-built servers or more commonly older PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the client's connection and by refusing to offer static IP addresses. A wonderful method to attain a reliable DNS hostname is by having an account with a dynamic DNS service. A dynamic DNS service will automatically update the IP address that a URL directs to when the IP address changes.

Some specific types of hosting offered by website host service providers:

  • File hosting service: hosts files, not web pages
  • Image hosting service
  • Video hosting service
  • Blog hosting service
  • Paste bin
  • Shopping cart software
  • Email hosting service

Host Management

The host may also provide an interface or control panel for managing the website server and installing scripts, as well as other modules and service applications like email. A web server that does not use a control panel for managing the hosting account, is generally referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).

Reliability and Uptime

The availability of a site is measured by the percentage of a year in which the site is publicly accessible and reachable via the internet. This differs from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it during network outage. A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the computers. The scheduled downtime is sometimes not included in the SLA timeframe and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a computer drops below that in the signed SLA, a hosting provider generally will supply a partial refund for lost time. How downtime is determined changes from provider to provider, therefore reading the SLA is crucial. Not all providers provide uptime info. Most hosting providers will guarantee at least 99.9% uptime which will provide for 43 minutes of downtime per month, or 8 hours and 45 minutes of downtime every year.

Obtaining Hosting

Web hosting is at times supplied as part of a general internet access plan from ISPs. There are also a number of free and paid providers offering web hosting.

A client is encouraged to evaluate the requirements of the application to choose what kind of hosting to use. Such considerations include database server software, scripting software, and operating system. Most hosting providers offer Linux-based web hosting which provides a wide range of different software. A usual configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The web hosting client may want to acquire other services, such as email for their business domain, databases or multimedia services. A client may also prefer Windows as the hosting platform. The user still can choose from Perl, PHP, Python, and Ruby, but the client may also use ASP.NET or ASP Classic. Web hosting packages often include a website content management system, so the end-user does not have to worry about the more technical parts.

Security

Because website hosting services host sites belonging to their customers, web security is an extreme issue. When a client agrees to use a website hosting service, they are passing on control of the security of their site to the service provider that is hosting the site. The level of security that a website hosting service provides is extremely important to a potential client and can be a major topic when considering which supplier a client should choose.

Website hosting computers can be targeted by malicious users in different ways, which include uploading malware or malicious code onto a hosted website. These attacks {may|might| be done for various reasons, including stealing credit card information, launching a Distributed Denial of Service Attack (DDoS) or spamming.
