Why more than one Knox service on the cluster?

[#1]

Guys,

I see that on the cluster of 40 nodes, on three edge nodes, we have knox previously installed. I am not sure why some one would configure three edge nodes. What are the advantages of having more than one Knox instance when Knox does not run in HA.

Hi @Smart Solutions

The main reason I see is to distribute load in case you have a lot of clients connecting to the edge nodes. You could imagine a load balancer in front of your Knox instances to distribute the load with only one entry point for your clients.

@Smart Solutions

You can put several Knox instances behind a load balancer to have HA. So multiple Knox instances are required for HA

Knox documentation gives an example on how to do it with Apache HTTP Server https://knox.apache.org/books/knox-0-9-0/user-guide.html#High+Availability
