The hierarchy model will not scale because then the high level ones have to
handle the sum of all messages from the lower level ones.  However simply
having many and having the client pick one at random will work. Second, once
we have tenant partitioning implemented, we can give tenants different names
... this is what salesforce does for example (our server is
na9.salesforce.com) and they use that to do updates / downtime etc. at
different times. That address of course can resolve to multiple IPs which
then load balance those set of tenants.

Anyway, we just need lots of users now to test all this stuff out :).

Yes, we can have a hierarchy of LBs with the new model. The average memory
footprint is even smaller when we run the LB without failover.

Very good news Azeez :). Can we run a heavy load test - like what we used to
run for eBay loads?

It also will be important to see how many worker nodes a single LB can
provide sufficient thruput for .. in eBay of course they have a hardware LB
at the highest level. I guess in the new model we can simply add more LBs
and once we do tenant partitioning we can do what Salesforce does and
essentially run multiple Stratos systems for the different partitions.

This has been implemented in the 3.2.0 branch and is almost complete. I'm
facing a minor issue in trying to getting the requested domain or complete

complete.

[Carbon-dev] Stratos service aware dynamic LB

2011-06-23 Thread Afkham Azeez 
Folks,
I'm thinking of getting $subject implemented since otherwise we will have to
have a large number of LBs for our services. The plan is to write a new
ServiceAwareDynamicLoadBalanceEndpoint, which will do LB based on the
service.

Axis2 already has support for handling multiple cluster domains, so we will
have to write a new Axis2LoadBalanceMembershipHandler which is service
aware.

The autoscaling would also need to be modified, but autoscaling is actually
a separate aspect, and we can even run the autoscaler separately if we are
going for the CPU load average based one.

Thoughts please.

Thanks
Azeez
