If I am reading data from multiple OS, and flavours of OS, network devices, around 60 different log sources altogether. Do I need a load balancer or does elastic have a loadbalancer in bulit? FYI, I do not want to use Filebeat here.

That really depends on what the log sources will do if logstash is temporarily down. If they lose data then I would suggest multiple logstash instances and a load balancer to avoid that.
