title: Sitecore Solr Loadbalancing
body: <p>I am working on a sitecore application where I need to set up 3 node cluster with solr configured in 2 servers and zoo keeper in all 3 servers .So I am looking for some solution to load balance solr instances . We are working on azure windows 2012 vms .The front end application is built on top of siteoCore and we are using IIS as our web server . So what option would be the best without going for a 3rd party load balancer like to use solr's internal load balancer "LBHttpSolrServer" or external azure provided load balancer ? Please suggest me but I can't go for a 3rd party load balancer . We have 5 CD servers . 
  Can I go for server farm using Application Request Routing Module ? So where I need to install this in CD servers or in SOLR servers ?</p>
