I have a basic question on distributed programming. My case is: I have a
module called launcher which opens a tcp port and listens to connections.
When a new connection is made, another process is launched to attend that
Now, when I think about distributing this for load balancing I see this
- Run various launchers on various computers and do the balancing through DNS.
- Run one launcher on one computer and make the launched processes run on
The first has the advantage of providing high-availability as well and all the
processes may access the same (mnesia) database. This is something that I
could possible do in C (or C++, Python or any language) using MySQL and MySQL
clustering, am I wrong ?
The second... the second, is it possible at all ? Can I launch a process in
another node and still let it handle a local socket ? And is it possible to
have a pool of nodes and launch new process in the one with less load ?
Somehow I feel like I am not seeing the whole picture (or that I am missing
some important Erlang feature).
Can anybody enlighten me ? (reading material is welcome).

PS: When I mention servers thing about typical Internet servers: web, smtp,
pop3, imap, dns, jabber, etc.
