Best recommendation for serach head cluster load balancer

[maede_yavari]

Hi,

I have deployed a search head cluster with 3 members and one deployer. based on splunk document, is recommends that run a third-party hardware or software load balancer in front of the clustered search heads.

does splunk recommend any special load balancer that is most compatible

Splunk does not recommend any specific load balancer.  They specify only that the LB employ layer-7 (application-level) processing and user sessions are "sticky" or "persistent."

Hi Richgalloway,

Thanks for your reply.

I consider HAProxy for that because I've had some experience about it. But I want to add LB several month later. does it maybe have some bad effect on the cluster performance? or create some fault on the search process?

Load balancers help the SHC perform better by evenly distributing users among all nodes.
