Various types of Web Hosting

Dedicated Hosting Service 

With dedicated hosting services the user has full control over the server and is the only client who uses the server. There are normally two types of dedicated hosting options which are managed and unmanaged. With managed hosting the client will have various support-personal or plans in place to assist them with managing the server and ensuring that things such as its security policies are up to date. Unmanaged will leave all the responsibility in the hands of the client which can be less expensive in some cases. In both cases having a dedicated server offers you much more control over what options are available on your server from mail programs to FTP services and so on. Naturally dedicated servers are much more expensive and therefore many webmasters opt for the cheaper shared or virtual private server options. With both types of dedicated hosting the servers are owned by the hosting company. 

Clustered Hosting 

In some cases it is not enough to have one server handling the needs of a website. For these cases clustered hosting becomes a viable solution. With clustered hosting multiple servers host the same information allowing a much larger base of users to access the information at one time. 

Virtual Dedicated Server 

Virtual dedicated servers are very similar to shared hosting except in how the allotment of resources is handled. Whereas with shared hosting all clients share the same CPU and bandwidth resources with virtual dedicated servers each client is guaranteed a set amount of CPU power and bandwidth. Virtual dedicated servers also offer their clients what is often referred to as "root" access to their virtual machine. This offers them more hands on control with how the machine runs including the ability to tinker with the operating system. 

Shared Web Hosting 

With shared web hosting a single computer referred to as a box or a server will generally hold a large number of websites. The number will depend on the company, the cost, and the hardware that makes up the machine. Shared hosting is often a reliable hosting option for most websites including both small business and personal use. The overall quality, speed, and cost will fluctuate significantly from host to host so it is important to do your homework before selecting a shared hosting center. Often websites which abuse or use more resources including CPU time or bandwidth will be shut down. If your website requires heavy resource allotment you will likely need to look into another hosting option. 

Home Server 

In some cases webmasters elect to manage their own web servers at home or at their place of business. This can be done on both a consumer-grade broadband connection or in some cases on something more capable. Home servers are much like colocation except for the loss of the expensive facilities which generally have backup power sources, industrial grade cooling systems, and various other benefits. Some ISPs do not allow their users to host their own websites so it is best to investigate this before attempting to setup your own web server.

Free Web Hosting 

Free web hosting is definitely the cheapest option available, however as we all know there's no such thing as a free lunch and this holds true with so called "free" hosting services as well. Free web hosts will often be advertisement supported and have very limited features, storage space, and bandwidth. Generally this is not a good option for any website which supports a business or needs to offer users a stable and efficient environment. Free hosting services are best for small web sites which are not intended to do much more than share a bit of info with a small group of friends.
