Why more than one Knox service on the cluster?

Expert Contributor

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.

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

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.
