A Beginner Guide to Web Hosting

What is web hosting? Whenever you visit a website, what you see on your web browser is essentially just a web page that is downloaded from the web server onto your web browser. In general, a web site is made up of many web pages. And a web page is basically composed of texts and graphic images. All these web pages need to be stored on the web servers so that online users can visit your website.

Therefore, if you plan to own a new website, you will need to host your website on a web server. When your website goes live on the web server, online users can then browse your website on the Internet. Company that provides the web servers to host your website is called web hosting providers.

A well-established web hosting provider sometimes hosts up to thousands of websites. For example, the Best Web Host of the Year 2003 award winner, iPowerWeb, is a web hosting company that hosts more than 200,000 websites. For that reason, a web hosting company need many web servers (essentially, these are computers) to store the website. And all these web servers are connected to the Internet through high speed Internet connection and housed in a physical building called data center. In order to guarantee all the web servers are safe, secure and fully operational all time, a data center is a physically secure 24/7 environment with fire protection, HVAC temperature control, virus detections, computer data backup, redundant power backup and complete disaster recovery capabilities.

What are the different types of web hosting? There are different kinds of web hosting companies out there with different characteristics. The main types of web hosts can be organized into the following categories:

a. Shared Hosting

In shared hosting (also known as virtual web hosting), many websites are sharing the space on the same physical web servers. Depending on the web host, a physical web server can hosts a few hundred to even thousand of different websites at one time. You may wonder if a physical web server is shared by so many websites, will the performance of the web server deteriorate? In fact, web servers are usually equipped with high-end powerful computer, therefore it can support up to a certain number of websites without any problem. But when the web server is overloaded and exceeded the reasonable number of websites that it can support, then you will begin to experience a slower response from the web server.

However, a reputable and experience web hosting provider will constantly monitor the performance of the web server and will add new web servers when deem necessary without sacrificing the benefits of the website owners. Since a physical web server is shared (diskspace, computer processing power, bandwidth, memory) by many websites, the web hosting provider can therefore afford to offer a lower hosting price. For the same reason, websites on the shared hosting would have to accept slower server response time. Typically, shared hosting plans start at $5 - $20 per month.

b. Dedicated Hosting

In contrast to shared hosting, dedicated hosting assigned a specific web server to be used only by one customer. Since a dedicated web server is allocated to only a single customer, the customer has the option to host single/multiple web sites, modify the software configuration, handle greater site traffic and scale the bandwidth as necessary. Therefore, dedicated hosting commands a higher premium and typically starts at $50 per month and can range up to $200 - $500 per month. As a result, dedicated hosting is regularly used by high traffic and extremely important website.

c. Co-location hosting

In dedicated hosting, the web server belongs to the web hosting providers and customers only rent the web server during the hosting period. While in co-location hosting, the customer owns the web server hardware and only housed their web server within the web hosting provider’s secure data center. In this way, the customer has full control over their web server.
