[Wikipedia-l] Phase IV software

[Neil Harris]

I would imagine that Phase III will last some time: the current software 
base is very robust and extensible, and can take lots more features 
without major re-architecture.

Even moving the database and various front-end servers to different 
machines is still possible with the current Phase III software. (By the 
way, this is a good reason not to consolidate all the national databases 
in a single database, as we will only have to unpick them later on for 
scaling reasons.)

Phase IV will presumably mark the  move to a distributed cluster 
architecture to cope with the sort of load that overwhelmed Britannica 
when they originally released their entire content for free.
