Shared Hosting

Web Publishing Tools, Techniques and Methods

Organizations can purchase either shared or dedicated web hosting services.   In a shared hosting environment, a website shares web server resources with other websites that are hosted on the same server.  Computer resources include computer disk space, bandwidth and CPU cycles.

In a dedicated environment, a website uses a dedicated computer that doesn't share resources with other websites.  This can provide greater flexibility and dependability but it requires that you assume more responsibility.

Shared Hosting Services

There are advantages and disadvantages to both shared web hosting and dedicated web hosting.  These are summarized in the table below:

Consideration Dedicated Server Shared Server
Costs more expensive less expensive
Data storage handles large data volumes depends on the plan you buy
CPU usage your site gets 100% of CPU other sites can impact yours
Bandwidth 100% of amount purchased other sites can impact you
Security more secure if properly set-up can be less secure
Maintenance responsibility is yours maintenance done centrally
Complexity more complex to set-up environment is set-up
Backup/Recovery you decide; you implement scheduled backups
Flexibility environment can be tailored pre-defined environment

In general, shared hosting plans are adequate for the needs of most organizations.  An organization can always upgrade to a dedicated server should issues be encountered in a shared environment.

A third web hosting option called "Virtual Private Hosting" or VPS has become quite popular.  This hybrid solution provides advantages from the two option previously discussed.
