Management Server Load Balancing

I noticed in the docs it states to LB the mgmt servers you need to use persistence.
Has anyone had any luck using cookie persistence? I am attempting to use HAproxy for LB, but anytime I enable persistence using cookies I get a 503 service unavailable.

I got Haproxy working by changing the LB type from RR to source IP hash. However I think I will checkout Zen LB as a training exercise.

Hi Michael,

While I have used HA Proxy, I am yet to use it for CloudStack management server
load balancing.

I have however, used Zen Loadbalancer (OpenSource and available at
http://www.zenloadbalancer.com) to load balance management servers with
HTTP and HTTPS “session” persistence without issues.

I’ll be happy to answer any queries on Zen LB if you have.


Regards.
