The web sites you visit are all hosted on servers somewhere on the Internet. Web hosts are companies that offer Internet-connected servers that provide space and bandwidth for a domain, for one or more web sites.

Large companies have private networks that allow them to host domains on their own equipment and IP address range. But for the majority of those who want an Internet presence, a ‘rented’ web host is a necessity.

There are a wide variety of hosting plans available. Some are free, others charge up to a $100 or more per month. Some provide nothing but a tiny amount of disk space with minimal network bandwidth and the web site owner is on his or her own for any thing else.

Other hosts offer a range of services, including server and email administration, backups, web site design assistance, troubleshooting and many others.

In the world of web hosting, you may often find yourself sharing a server with anywhere from one to a thousand or more other web sites. That allows the web hosting company to keep equipment and staff expenses lower.

Many web sites are simple and low-volume enough that the arrangement works fine. When you or one or more of the others grow, it may be helpful to consider a dedicated server.

A dedicated server, as the name suggests, hosts only your domain. You can put one web site on it, or as many as you wish. You control the access.

You may also, as an option, take over much of the server administration yourself. That may save you money on support costs, but cost you considerable time. If you don’t have the expertise, you can end up costing yourself much more than you save.

In order to carry out those administrative functions yourself, even if you hire help, it’s desirable to have some technical knowledge under your belt. Some of that knowledge will be useful, even for day-to-day tasks apart from dealing with emergencies.

FTP, email administration, backup methods and other technical areas are among the more common areas you’ll need to be at least somewhat familiar with.

When your web site grows to a certain size and level of complexity, you’ll begin to find it worthwhile to look at implementing a database. But that brings with it a still higher level of ability, both technical and logistical or creative.

Implementing a database can be relatively simple. Designing one that provides what you want, with decent performance and maintenance that doesn’t become a nightmare, will take some careful thought.

Not everyone has the temperament for that type of work, especially those who prefer graphical design, content creation or development, and the many other web site tasks that are part of every implementation.

There are other, more low level administrative matters. Managing disk space, maintaining domain names, dealing with registration and changes, and a number of other ‘utilitarian’ tasks are also not everyone’s cup of tea.

Some understanding of how DNS works, as well as the design of the Internet itself, are helpful. That provides a good context for understanding the role of some of those tasks.

When you begin to seek out a web host to implement a web site, consider all these factors and look in the mirror. What kind of web hosting you should pursue is determined by a combination of who you are and what’s being offered.
