[Bhagwan Basnet (Aakash)]

Hi,

we are moving our Bitbucket server to Data Center Edition and as a part of it we are building a server and necessary infrastracture, we have planned to make 3 cluster for our bitbucket server and elesticsearch as well.

We are stuck at elesticsearch stuff, what kind of  loadbalancer should be and what requirement should be look like?

Can we also have a simple standalone server without any load balancer and cluster installation?

please provide us the best solution with how to get the elesticsearch installation done with loadbalance and cluster installation.
