[Discuss] Load Balancer Changes for 4.1.0-M3
Hi,
We have now fixed the following issues identified with the load balancer:
- Fixed messaging component dependencies in load balancer package.
- Fixed an issue in messaging component which raised a class cast exception
in debug mode.
- Added generated service host port to the member port map. This will
overwrite the port value given by the cartridge definition with the
generated service host port, if the cluster is kubernetes.
- Now the load balancer will apply the load balancing algorithm on the list
of members found in the cluster, not on the list of service proxies. We
could improve further in a future milestone.
Thanks

Posted by Imesh Gunaratne <im...@apache.org>.
Thanks Raj for explaining the solution.
Currently the load balancer does not list the available kubernetes service
proxies for a given stratos service cluster and then load balance requests
among them, rather it uses the member/container list to do it. I think we
will need to balance the load among the service proxies to optimally
balance the load among all the containers in all the hosts. Will implement
this for the next milestone.

Re: [Discuss] Load Balancer Changes for 4.1.0-M3
Posted by Rajkumar Rajaratnam <ra...@wso2.com>.
Yep :)
Only thing we did is that we added allocated service port to the member
object (member's port map) so that LB can read it when it receives member
events.

Re: [Discuss] Load Balancer Changes for 4.1.0-M3
Posted by Rajkumar Rajaratnam <ra...@wso2.com>.
Hi,
Let me explain how it works now.
Each member object has kubernetes host IP (in which that member is created)
and service proxy port. LB is working as previously where it distributes
requests between members. Since member's IP and port is now kubernetes host
IP and service proxy port, LB actually distributes requests to the
kubernetes service proxies.
I will attach LB log. You will see that LB is sending request to the
kubernetes service proxies.
I am accessing via cluster host name and proxy port (
http://myphp.apachestratos.org:8281/).
