It is a kind of a hosting at which sites of a plenty of users dynamically divide among themselves resources of one physical server - memory, disk space and processor time. From this the basic restrictions, imposed a hosting follow providers on sites of users:

• The maximal disk space is limited a reasonable limit in 2-3 Gb. It is that limit at which achievement at any popular project is expedient for upgrade on the virtual allocated server (VPS/VDS) or the allocated physical server (dedicated);
• Any user process is limited by a 10 seconds of central processor time. Restriction is needed that the average delays in users service inquiries a server did not exceed typical average delays in the data link;
• Restrictions use by the user processes of random access memory of physical server. Even at dynamic distribution of memory the server software provides reservation RAM that can bring to delays in service on most visited projects of a server.

Advantages of such kind of a hosting: low cost, simplicity of administration. Lacks: dependence on other users with which you divide resources physical server, impossibility of start of processes, unlimited on time, a low level information safety.

• An opportunity of installation and adjustment of own non-standard configuration Apache, PHP, Perl, own server of databases and FTP;
• Low cost, in comparison with rent or purchase of the physical allocated server.

It is possible to carry to lacks only all a little bit limited opportunities on resources and low in comparison with the allocated physical server a level of information safety.

The basic platforms on which services of the given type - Linux are realized, less often Windows.
