Shared (Virtual) Hosting
Shared hosting is very cost-effective.
With shared hosting, your web site gets its own domain name, and is hosted on a powerful server along with maybe 100 other web sites.
Shared solutions often offer multiple software solutions like e-mail, database, and different editing options. Technical support tends to be good.
With dedicated hosting, your web site is hosted on a dedicated server.
Dedicated hosting is the most expensive option. This option is best suited for large web sites with high traffic, and web sites that use special software.
You should expect dedicated hosting to be very powerful and secure, with almost unlimited software solutions.
Collocation means “co-location”. Collocated hosting lets you place your own web server on the premises (locations) of a service provider.
This is pretty much the same as running your own server in your own office, only that it is located at a place better designed for it.
Most likely an ISP will have dedicated resources like high-security against fire and vandalism, regulated backup power, dedicated Internet connections and more.
