[Typo3-dev] Distributet Typo3 site, how to approach this?

[Martin Seebach]

You'll want to look at distribution at the database level. MySQL does 
replication[1], and if I'm not mistaken, it works quite well.

What you do, is put a master at the top of a tree (at the mother.com 
site), and make all changes (INSERT, UPDATE etc) to that. Then a number 
of slaves (located at the daughter sites) will be updated automatically.

It works best when there are significantly more reads than writes to the 
database - which is true for a CMS.

I am no expert on the subject, I've just experimentet a bit on a amateur 
basis.

You can use a distributed filesystem, such as Coda[2] to keep files in 
sync across servers.
