Webhosting: A Guide

By Matt Ewing


Constructing a website is a vital part of increasing the scope of your business world and expanding your online presence. Once you have this notion, you start to consider a possible domain name and then look into Webhosting for your potential site. You need to think about what web host is right for you and that is why we now offer you a simple guide to web hosting.

How would you define web hosting?

Not just a domain name, but a group of files linked together by HTML code in order to put on view the text and graphics on a computer is what a website is all about. The compilation of your created files has to be saved somewhere in the computer (with special software) to show others, provided it has an Internet access. Generally speaking, web hosting is a renting space on a web server. A web server lets a computer have the requests from the Internet for the website files that has been stored. It also does send the files to the Internet for the purpose of displaying by the requesting computer. It is called 'server' fir its same approach like a waiter in a restaurant.

A web server endows you with many services. It not only exhibits your files to the Internet users but also it can create email addresses on the basis of your domain name in order to send and receive email with them. Added to this service, a web server with a variety of software lets your website run programs, create and manage databases, exhibits video, and many other functions that can be of use. Computer is no barrier here because here software is everything and can make it a server.

As it is a service being provided, there is a fee for purchasing a web host and this money goes towards the general upkeep and maintenance of the software and hardware of the server. This payment is also used to keep the server online, to ensure it is held securely and that a rapid internet connection is maintained. Payment also goes towards paying for the person who maintains this service. It may be possible for the user to do it all themselves but having a dedicated provider do the tasks for you is usually a better idea for most people. Yes, this incurs a charge but it can be worthwhile providing the person does it in reliable form.

Varieties of Web Hosting

Shared Hosting- Yahoo! may be meant for everyone to use the internet but not every website is like that meaning they are targeted at a particular niche which means there i no requirement for a large amount of pages. This means most websites do not need an infinite resource of the server. The majority of servers are extremely powerful which makes them able to handle a huge amount of sites. Just fewer than 100% of websites use the shared hosting method which sees more than one website placed on a particular server. This method is used because it is easily the cheaper option as it spreads the cost of resources of the server in addition to the resources, which makes it a popular choice. Another name for shared hosting is virtual hosting which enables clients to have access to a number of available resources. Depending on how much space or how many resources are being used, the price will vary. The more of a service such as email accounts, disk space or bandwidth being used, the higher the cost will be.

Dedicated Hosting- When you feel the need of having lots of visitors for your big website or you think about dominating resources or feel antipathy towards sharing the server with anyone else who might crash it, you need a web server that is entirely dedicated to you. So, dedicated hosting is all about renting the service of an entire server. Ownership of machine and responsibility for maintaining the hardware and the web hosting software still remains in the realm of the web hosting company but you gain control over the configuration and use of the server. Semi-dedicated hosting is another interesting term where a web server extends service to 2-4 clients with a strong line of demarcation between them. This is also treated as managed hosting for here hosting company maintains the server. Having clarified all the ins and outs, it goes without saying that dedicated hosting is more expensive than shared hosting.

Server Co-Location- If money was no object, a great option is to contain everything within your own web server and domain and this can be done by buying a server and looking after it yourself. However, there are many issues that can arise from this and would you be able to react to power shortages, natural disasters, floods, break ins, staff error and many other problems that may cause problems? All of these issues may prevent your server from running on a speedy internet connection but help is at hand from a data center. Placing your server in a secure outlet with a guaranteed power source and reliable and fast internet connection is called a Co-location. This situation placed the client in charge of maintaining the software and hardware needs of the server as the data center will not become involved in this issue. If a client has the talent, ability and hours to look after this form of server, it can be an improved and less expensive variant compared to dedicated hosting.

UNIX Hosting- Although a number of web host styles have been talked about so far, it is more accurate to say they have been variants on UNIX as this is what the majority of web severs are operated on. The UNIX operating system was developed by universities as a method of providing access to networks and servers and features in many different forms and designs. This is because this form of operating system was created with 'open source protocol' which enabled many amendments and adjustments to be made. There are a great number of variations produced such as FreeBSD, SuSE, Debian and Red Hat Linux all of which stem from Linux and BSD, which are considered to be the popular versions. A huge benefit of using UNIX as a form of hosting is its low cost and the fact that it provides a better alternative to many operating systems. This reduction in costs allows the web host to charge a lower price for their service or allows them to have a larger profit margin. Other benefits in using this style of hosting platform is that the UNIX is considered to have high security, it is considered extremely powerful and it offers great stability. You may hear the phrase 'UNIX hosting' used quite a lot and this is because it refers to any platform that originated from the first UNIX.

Windows Hosting- It is no secret that Microsoft offers a huge range of commercial products and services and the Windows Server 2003 is but one of them. This product needs a license for the buyer to operate it and this immediately makes it a costlier system than its competitors. Considering it is dearer, it also provides less power and a lower level of security than UNIX systems, which are ideal for clients who are in a network situation. Many programmers have a preference for ASP, ASP.NET and ColdFusion and these scripting languages have to be run on server that is dedicated to Windows with the Microsoft SQL server or Microsoft Access and its database programs being strong examples. If you like the concept of being able to use these then you will require having a Windows host.
