San Diego Website Hosting

A web hosting service is a kind of internet hosting service that allows people and companies to make their site available via the world wide web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing internet connectivity, typically in a data center. Web 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

Up till 1991, the internet was limited 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 tiny number of website pages. The world wide web protocols had only just been put together and not till the end of 1993 would there be a graphical website browser for Mac or Windows computers. Even after there was increased internet access, the situation was complicated until 1995.

To host a website on the internet, an individual or organization would need their own computer or server. As not all organizations had the budget or capability to complete this, website hosting services began to supply services to host users' websites on their own servers, without the customer needing to assemble the necessary infrastructure neededd to operate the web site. The owners of the sites, also called webmasters, would be able to design a website that would be hosted on the web hosting service's server and published to the internet by the website hosting service.

As the number of users on the world wide web grew, the pressure for companies, both big and tiny, to have an online presence increased. By 1995, companies such as GeoCities, Angelfire and Tripod were providing 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 very little processing. A lot of internet service providers (ISPs) provide this service with no cost to subscribers. Individuals and companies may also acquire website page hosting from alternative service providers.

Free web hosting service is offered by various organizations with limited services, sometimes supported by advertisements, and sometimes limited when compared to paid hosting.

Single page hosting is at times sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting at times has a higher expense 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 organization may use the computer as a website host to offer details of their products and services and facilities for online orders.

A complicated website calls for a more expanded package that supplies database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities allow clients to develop 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 safe.

Types of Hosting

Internet hosting services can run web servers. The scope of web hosting services varies quite a bit.

Shared Website Hosting Service

One's website is placed on the same server as many other websites, 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 kind of service can be relatively basic and not flexible in terms of software and updates. Resellers sometimes sell shared web hosting and web companies generally have reseller accounts to provide hosting for clients.

Reseller Website Hosting

Reseller website hosting allows clients to become web hosts themselves. Resellers may 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 differentiate tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers provide a similar service to their provider's shared hosting plan and offer the tech 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 handed out in a way that doesn't directly reflect the shared hardware. VPS will sometimes be allocated resources based on a one server to many VPSs relationship, but, virtualization may be chosen for varying reasons, which includes the possibility to relocate a VPS container between servers. The users might have root access to their own virtual space. Users are often responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may offer server administration jobs for the client (managed server).

Dedicated Hosting Service

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

Managed Hosting Service

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

Colocation Website Hosting Service

Almost the same as the dedicated website hosting service, but the user owns the colocation server; the hosting company offers physical space that the computer takes up and manages the computer. This is the most powerful and costly type of web hosting service. In most cases, the colocation provider may supply little to no support directly for their client'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 accept 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 modern type of hosting platform that permits customers powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website might be more stable than alternatives since other computers in the cloud can take over when a single piece of hardware fails. Also, local power failures or even natural disasters are less of a problem for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also allows providers to charge users just for resources used by the customer, instead of a flat amount for the amount the customer guesses they will consume, or a fixed amount upfront hardware investment. Alternatively, the decentralization may provide customers less control on where their data is located, which could be a deal breaker for users with data security or privacy worries.

Clustered Hosting

Having a number of servers host the same content for better resource utilization. Clustered servers are a good solution for high-availability dedicated hosting, or having a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Generally website hosts use clustered hosting for their shared hosting plans, as there are many options to the mass managing of customers).

Grid Hosting

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

Home Server

Usually, a sole 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 older PCs. Some internet service providers actively attempt to block residential servers by not allowing incoming requests to TCP port 80 of the customer's connection and by refusing to offer static IP addresses. A easy way to have a reliable DNS hostname is by obtaining an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL directs to when the IP address changes.

Some specific kinds 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

Host Management

The host might 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 website server that doesn't use a control panel for managing the hosting account, is sometimes 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 available 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 specific amount of scheduled downtime per year in order to perform maintenance on the systems. This scheduled downtime is often 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 server drops lower than that in the signed SLA, a hosting provider at times will supply a partial refund for time lost. How downtime is determined is different from provider to provider, therefore going through the SLA is important. Not all providers show uptime stats. Quite a few hosting providers will guarantee at least 99.9% uptime which will provide for 43 minutes of downtime each month, or 8 hours and 45 minutes of downtime each year.

Obtaining Hosting

Web hosting is often supplied as part of a complete internet access plan from internet service providers. There are also a lot of free and paid providers offering web hosting.

A client needs 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. Many hosting providers provide Linux-based website hosting which provides a wide range of different software. A typical configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The website hosting user might want to acquire other services, such as email for their business domain, databases or multimedia services. A user might also choose Windows as the hosting platform. The client still can choose from Perl, PHP, Python, and Ruby, but the client may also use ASP.NET or ASP Classic. Web hosting packages at times include a website content management system, so the end-user does not have to be bothered about the more technical components.

Security

Since website hosting services host sites belonging to their clients, web security is a vital item. When a customer agrees to use a web hosting service, they are passing on control of the security of their website to the service provider that is hosting the site. The degree of security that a web hosting service offers is quite important to a prospective client and can be a major subject when considering which supplier a customer should choose.

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