Do Mapserver enables distributed processing spatial data?

[Luis Angel Monge De La Cruz]

Thanks for the suggestions. These options sound good.

But the reason to have the database in more than one computer, is that
really so are available, it is unlikely that the information is integrated
into a single site, the application is for risk management, where there are
layers of information disseminated in several locations, including various
sources, such as graphics files, dbf, and postgresql. I am currently
studying for a master and my idea is to propose improvements to mapserver in
this regard.  ¿how? Developing a mechanism to be included in the file. Map
more than one source to a layer, so something like a mirror, and that the
choice of the server is based not only on the availability of the source,
also the bandwidth , reliability and others.
