Can anyone suggest some reading material or a tutorail how to set up a load balancer on cluster and use it with any service?
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?
2) 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?
3) 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 ?
5) When you set up for group of same servers have a Round-Robin DNS do you still need a loadbalancer to serve over http and https?
Please let me know if my questions make sense or suggest an idea and literature to go through.
