A website hosting service is a kind of internet hosting service that allows people and companies to make their website accessible via the world wide web. Website hosts are companies that supply space on a server owned or leased for use by users, as well as providing internet connectivity, usually in a data center. Website hosts can also supply 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 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 till the end of 1993 would there be a graphical web browser for Mac or Windows computers. Even after there was increased internet access, the situation was challenging until 1995.
To host a web site on the internet, an individual or company would need their own computer or server. As not all organizations had the money or capability to manage this, web hosting services began to provide services to host users' websites on their own servers, without the client needing to own the necessary infrastructure neededd to run the website. The owners of the sites, also referred to as webmasters, would be able to construct a website that would be hosted on the web hosting service's server and published to the web by the website hosting service.
As the number of users on the world wide web increased, the demand for organizations, both big and small, to have an online presence increased. By 1995, organizations such as GeoCities, Angelfire and Tripod were offering free hosting.
Classification
Smaller Hosting Services
The most simple is awebsite page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web interface. The files are sometimes delivered to the web "as is" or with almost no processing. A lot of internet service providers (ISPs) supply this service free to users. People and organizations may also acquire website page hosting from alternative service providers.
Free website hosting service is offered by various organizations with limited services, generally supported by advertisements, and often limited when compared to paid hosting.
Single page hosting is generally sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting sometimes has a greater cost depending upon the size and type of the site.
Larger Hosting Services
Many big companies that are not ISPs need to be permanently connected to the web in order to send email, files, etc. to other sites. The organization may use the computer as a website host to provide details of their goods and services and facilities for internet-based orders.
A complex website calls for 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 safe.
Types of Hosting
Internet hosting services can run web servers. The scope of website hosting services differs quite a bit.
Shared Web Hosting Service
One's website is placed on the same server as many other sites, ranging from a few sites to hundreds of websites. Usually, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this kind of service can be quite simple and not flexible in terms of software and updates. Resellers sometimes sell shared web hosting and web companies generally have reseller accounts to offer hosting for customers.
Reseller Website Hosting
Reseller website hosting permits clients to be web hosts themselves. Resellers may function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may differentiate a great deal in size: they may have their own virtual dedicated server to a colocated server. Many resellers supply a nearly identical service to their provider's shared hosting plan and provide the tech support themselves.
Virtual Dedicated Server
Also known as a Virtual Private Server (VPS), it separates server resources into virtual servers, where resources can be split up in a way that doesn't directly reflect the underlying hardware. VPS will sometimes be allocated resources based on a one server to many VPSs relationship, however, virtualization might be done for a few reasons, which includes the ability to move a VPS container from one server to another. The users may have root access to their own virtual space. Users are typically responsible for patching and maintaining the server (unmanaged server) or the VPS provider may offer server administration tasks for the client (managed server).
Dedicated Hosting Service
The user gets his or her own web server and gains complete control over it (user has root access for Linux/administrator access for Windows); however, the client typically does not own the server. One kind of dedicated hosting is self-managed or unmanaged. This is usually the least expensive for dedicated plans. The user has full admin access to the server, which means the client is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The customer gets their own web server but is not allowed full control over the server (the customer is not given root access for Linux/administrator access for Windows); but, they are allowed to control their data via FTP or other remote management software. The customer is not permitted complete control so that the provider can guarantee the quality of service by not granting the customer to change the server or perhaps create configuration issues. The customer typically doesn't own the server. The server is leased to the customer.
Colocation Website Hosting Service
Similar to the dedicated web hosting service, but the user owns the colocation server; the hosting company offers physical space that the server takes up and manages the server. This is the strongest and costly type of web hosting service. In most cases, the colocation provider may offer little to no help directly for their user's computer, providing only the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the customer would have their own administrator visit the data center on-site to do any hardware upgrades or changes. Formerly, many colocation providers would allow any computer configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting organizations now expect rack mount enclosures and standard system configurations.
Cloud Hosting
This is a relatively modern kind of hosting platform that permits customers strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site might be more reliable than others as other computers in the cloud can compensate when an individual piece of hardware breaks. Also, local power disruptions or even natural disasters are less problematic for cloud hosted websites, as cloud hosting is not centralized. Cloud hosting also permits providers to bill users only for resources consumed by the user, rather than a flat rate for the amount the user thinks they will use, or a fixed cost upfront hardware investment. Alternatively, the decentralization may provide clients less control over where their information is located, which could be challenging for customers with data security or privacy concerns.
Clustered Hosting
Having a group of servers host the same content for stable resource utilization. Clustered servers are a wonderful solution for high-availability dedicated hosting, or having a scalable web hosting system. A cluster may separate website serving from database hosting capability. (Often website hosts use clustered hosting for their shared hosting plans, as there are multiple options to the mass managing of customers).
Grid Hosting
This form of distributed hosting is when a server cluster performs like a grid and is made of multiple nodes.
Home Server
Often, a single server located in a private residence can be used to host one or multiple sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some internet service providers purposefully attempt to block home servers by not allowing incoming requests to TCP port 80 of the client's connection and by refusing to supply static IP addresses. A wonderful way to have a reliable DNS hostname is by having an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.
Some specific types of hosting offered by web host service providers:
- File hosting service: hosts files, not website pages
- Image hosting service
- Video hosting service
- Blog hosting service
- Paste bin
- Shopping cart software
- Email hosting service
Host Management
The host might also provide an interface or control panel for managing the web server and installing scripts, as well as other modules and service applications like email. A web server that doesn't 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 website 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 as in the event of a network outage. A hosting provider's Service Level Agreement (SLA) might include a specific amount of scheduled downtime per year in order to perform maintenance on the computers. This scheduled downtime is at times excluded from 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 system drops below that in the signed SLA, a hosting provider sometimes will provide a partial refund for lost time. How downtime is calculated is different from provider to provider, therefore understanding the SLA is crucial. Not all providers publicly display uptime information. 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 sometimes provided as part of a larger internet access plan from internet service providers. There are also a number of free and paid providers offering web hosting.
A client must evaluate the requirements of the application to choose what type of hosting to use. Such considerations include database server software, scripting software, and operating system. Most hosting providers provide Linux-based web hosting which offers 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 might want to obtain other services, such as email for their organization domain, databases or multimedia services. A user might also choose Windows as the hosting platform. The user still can choose from Perl, PHP, Python, and Ruby, but the user may also use ASP.NET or ASP Classic. Website hosting packages often include a website content management system, so the end-user doesn't have to be concerned about the more technical components.
Security
Since web hosting services host websites which belong to their clients, internet security is a very important concern. When a client agrees to use a web hosting service, they are handing over control of the security of their website to the company that is hosting the website. The degree of security that a web hosting service offers is very important to a potential customer and can be a major topic when deciding which provider a client will choose.
Web hosting computers can be targeted by malicious organizations in different ways, including uploading malware or malicious code onto a hosted website. These attacks {may|might| be done for different reasons, including stealing credit card info, launching a Distributed Denial of Service Attack (DDoS) or spamming.
