Top Website Hosting

A web hosting service is a kind of internet hosting service that allows people and organizations to make their website available 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, 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 created and not until the end of 1993 would there be a graphical web site browser for Mac or Windows computers. Even after there was some opening up of internet availability, the situation was confused until 1995.

To host a website on the internet, a person or company would need their own computer or server. As not all companies had the budget or capability to complete this, web hosting services started to offer to host users' websites on their own servers, without the customer needing to purchase the necessary infrastructure required to operate the web site. The owners of the websites, also referred to as webmasters, would be able to develop a site 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 large and tiny, to have an online presence grew. By 1995, companies such as GeoCities, Angelfire and Tripod were supplying free hosting.

Classification

Smaller Hosting Services

The most basic is awebsite page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web site interface. The files are usually delivered to the web "as is" or with minimal processing. Quite a few internet service providers (ISPs) provide this service free to users. People and organizations may also acquire web page hosting from alternative service providers.

Free web hosting service is offered by various companies with limited services, at times supported by advertisements, and sometimes 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 sometimes has a greater expense depending upon the size and type of the site.

Larger Hosting Services

Many big organizations that are not ISPs need to be permanently connected to the web to send email, files, etc. to other sites. The organization may use the computer as a website host to supply details of their products and services and facilities for online orders.

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

Types of Hosting

Internet hosting services can run web servers. The scope of website hosting services differs greatly.

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 sites. Generally, all domains may share a common pool of server resources, such as RAM and the CPU. The features that are available with this kind of service can be quite basic and not flexible in terms of software and updates. Resellers sometimes make available shared web hosting and web companies often have reseller accounts to provide hosting for clients.

Reseller Website Hosting

Reseller website hosting permits clients to be website hosts themselves. Resellers can function, for individual domains, under any combination of these types of hosting, depending on who they are working with as a reseller. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers supply a similar service to their provider's shared hosting plan and supply the technical support themselves.

Virtual Dedicated Server

This is 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 generally be allocated resources based on a one server to many VPSs relationship, but, virtualization may be chosen for different reasons, including the ability to move a VPS container between servers. Users might have root access to their own virtual space. Customers are often responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may offer server admin jobs for the client (managed server).

Dedicated Hosting Service

The user gets his or her own website server and gets full control over it (user has root access for Linux/administrator access for Windows); but, the client generally doesn't own the server. One type of dedicated hosting is self-managed or unmanaged. This is usually the least expensive for dedicated plans. The client has full admin 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 his or her own website server but they are not allowed full control over the server (the customer is denied root access for Linux/administrator access for Windows); but, they can control their data via FTP or other remote management tools. The user is not granted full control so that the provider can guarantee the quality of service by not giving the user to modify the server or perhaps create configuration issues. The client often doesn't own the server. The server is leased to the customer.

Colocation Web Hosting Service

Almost the same as the dedicated web hosting service, but the user owns the colocation server; the hosting company offers physical space that the computer takes up and takes care of the server. This is the most powerful and expensive type of website hosting service. In most cases, the colocation provider may provide little to no support directly for their client's server, providing just the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the customer would have their own administrator go to the data center on-site to do any hardware upgrades or changes. Formerly, a lot of colocation providers would allow any server 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 kind of hosting platform that permits clients strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website might be more reliable than others as other servers in the cloud can take over when a single piece of hardware stops working. Also, local power outages or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is not centralized. Cloud hosting also permits providers to invoice users just for resources consumed by the client, instead of a flat amount for the amount the client guesses they might use, or a fixed cost upfront hardware investment. Alternatively, the decentralization might give users less control on where their data is located, which could be challenging for customers with data security or privacy concerns.

Clustered Hosting

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

Grid Hosting

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

Home Server

Generally, a sole server situated in a private residence can be used to host one or multiple web sites from a usually consumer-grade broadband connection. These can be purpose-built servers or more commonly older PCs. Some internet service providers actively work to block residential servers by stopping incoming requests to TCP port 80 of the client's connection and by refusing to supply static IP addresses. A well-known method to get a reliable DNS hostname is by obtaining an account with a dynamic DNS service. A dynamic DNS service will automatically update the IP address that a URL points to when the IP address changes.

Some specific kinds of hosting provided 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 could 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 often 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 website 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 when there is a network outage. A hosting provider's Service Level Agreement (SLA) might include a certain amount of scheduled downtime each 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 lower than that in the signed SLA, a hosting provider often will offer a partial refund for time lost. How downtime is calculated changes from provider to provider, therefore going through the SLA is crucial. Not all providers release uptime information. A number of hosting providers will guarantee at least 99.9% uptime which will allow for 43 minutes of downtime per month, or 8 hours and 45 minutes of downtime every year.

Obtaining Hosting

Web hosting is generally provided as part of a complete internet access plan from ISPs. There are also a lot of free and paid providers offering website hosting.

A customer 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. a lot of hosting providers supply 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 website hosting user may want to have other services, such as email for their organization domain, databases or multimedia services. A client might also prefer Windows as the hosting platform. The user still can choose from Perl, PHP, Python, and Ruby, but the customer may also use ASP.NET or ASP Classic. Website hosting packages at times include a web content management system, so the end-user doesn't have to worry about the more technical parts.

Security

Since website hosting services host websites which belong to their customers, internet security is a vital topic. When a customer agrees to use a website hosting service, they are passing on control of the security of their website to the service provider that is hosting the website. The degree of security that a web hosting service supplies is extremely important to a prospective client and can be a major consideration when considering which supplier a client will choose.

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