Subject Updated Cluster Architecture
Date Tue, 15 Jan 2013 00:39:38 GMT
I have updated the graph for the cluster architecture:
https://cwiki.apache.org/confluence/display/OPENMEETINGS/Cluster+Master-Slave+overview

The biggest change is that master and slave have the same database (or
database-cluster). That makes it a lot easier.
The master will still need to coordinate the load, so he needs to ping all
slaves to collect the load and redirect to the slave that has the least
traffic (or that actually already hosts the requested room)
However the slaves can handle both HTTP and RTMP traffic. There is no need
to separate that anymore as the slave would use the same database as the
master.

For syncing the recordings and other files to the master HDD there are
multiple solutions. One would be like Maxim proposed to do a Samba mount.
The other is for example to use some RSync scripts. This can be decided by
the end user on its own.

I think this is more suitable then the previous approach and uses the
standard mechanisms for clustering.

Let me know what you think about that.

Thanks!
Sebastian
