I thought TCP/SSL proxy was better for this.

Wait, can an HTTP(S) load balancer even do that?

You should go with a Network load balancer for preserving source IP.

I thought internal load balancers were for private networks, so they definitely wouldn't apply to this global solution.

I feel like the HTTP(S) load balancer wouldn't work here since it operates at a higher layer, but I can't recall the specifics.

I think we need to use a Network load balancer for preserving the source IP, but I'm not entirely sure.

I remember practicing a similar question, and I think the TCP/SSL proxy load balancer might also be an option, but it doesn't seem right for this case.

I think the best approach here is to walk the actual process from beginning to end. That way, you can see firsthand how the process works and identify any pain points or areas for improvement.

Ugh, I'm drawing a blank on the specific command name. But I know it's one of the standard process management tools, so I'll try to eliminate the obvious wrong answers.

I remember the Service Broker pattern being a crucial part of Enterprise Service Bus, but I'm not entirely sure about the Schema Centralization part.
