1)Can we use loadbalancer setup alone as a single entry-point for users and for callbacks from any service ? or does it have to be used with any other?
Does the servers pointing to loadbalancer need to be configured to virtual IP so that request from http , or https gets served? or the http/https request can be pointed directly to loadbalancer without a virtual IP as discussed above?
The load balancer should be configured for round-robin between the servers to distribute the requests, is it a feature of load balancer ?
4)In order to have full HA, the load balancer should also have HA support, or it becomes a single point of failure? Are they any open source stack available with this feature and can you suggest a few ?
Please let me know if my questions make sense or suggest an idea and literature to go through.
