Cloud hosting involves hosting files "in the cloud", which means they are stored via a remote server and can be accessed almost anywhere (and usually from any computer) through the internet. Cloud Hosting users appreciate this flexibility as well, as they can still access files when they are away from their home office or computer.
Many services, such as HostZilla, offer FREE Cloud Hosting up to 100MB. They also make it easy to upgrade for as low as $15/year, which is only a little bit more than $1 a month. That is a small price to pay for unlimited cloud web space.
The HostZilla website is easy to navigate and simple to use. It outlines available features easily and I would definitely recommend it.
