The latter it’s software inside each server. You can’t do anything with it it’s just there.

You may need to follow different commands to restart Tomcat now? Not sure and didn’t see anything about that.

I can’t find any feature documentation. Is this a new thing that we can take advantage of by configuring multiple servers or something? OR is it just backend stuff that I don’t have to worry about nor can I configure?

New service in front of Tomcat to make tomcat services more performant.

What’s HA Proxy?

Some may have heard of the work to help make performance better and here’s a neat little caveat for the new HAProxy for Tomcat:

“Restart of the Cisco TFTP service will temporarily result in the unavailability of the web services up to 10 seconds on that node where HAProxy undergoes restart.”

I know at least in my environments I restart TFTP during business hours when necessary. Need to think about that more in smaller environments since now you could be turning off AXL and such briefly.
