Web hosting Categories Most hosting packages are grouped into broad categories, the most known of them are
1- The shared hosting: Each server hosts multiple sites, up to several thousands, in order to share the costs. The main advantage of this package is the price, the main disadvantage is that the clients are not server “administrator” and they are often depended on the goodwill of the host if they want a particular technology. In some configurations of shared hosting, the user can be an administrator of a virtual server, on which the site is deployed. However, he continues sharing system resources with other customers.
2- Dedicated accommodation: The customer has its own server, and can generally be administered as desired, which is the main advantage of this type of offer. The server vendor remains the owner of the server. The disadvantages are: the price is much higher than shared hosting, and skills are needed to administer the machine correctly.
3-Virtual dedicated hosting via a hypervisor that offers customers the flexibility of a dedicated (the client manages his machine at its desire) by providing a virtual machine that uses a portion of server resources (physical) by techniques virtualization (computer).
