RE: [SSI-users] Apache and MySQL Cluster

[Walker, B. J <bru...@hp...>]

I don't believe it matters.  In OpenSSI there are in effect 2 forms of
load balancing - connection load balancing via LVS and process load
balancing.  For Apache/httpd, I recommend just using the connection load
balancing, which involves running httpd on all or several nodes and
having HA-LVS and the CVIP spread the connection load to the servers on
each node (which can then be different processes or thread or whatever).
One could consider trying to process migrate httpd services and some
have tried it.  I think it should only be considered if the service
being done is long running and compute intensive.  If that scenario
applies, the httpd services would have to be distinct processes and not
clones or threads.
