I have experience with the horizontal scale out but not with the vertical scale out.
If I scale out the presentation service, I believe it will have two different port numbers. Does it mean that I have to access both of them with separate port numbers as shown below as an example?
ps1 : https://server:9502/analytics
ps2 https://server:9602/analytics
If yes, Do I need to place a load balancer in front of them like I do for horizontal clustering?
