Awesome video, I understand most of the good points of stateless, I guess making a web application whether a session is an important concern but not important at scaling we probably would use php session as a way to maintain the session or any other programming that gives us this set of tools. but regarding the we wouldn't scale horizontal, thanks man

Correct! Just make sure to add logic to invalidate the cache

Hi Hussein, thanks for your channel. I really appreciate the work you are doing on this. For this video, I would like to know if in the case of stateful app, is it possible to use an "intelligent" LB such that the requests for a given user go always to the same server. In this way we can also have a cache into the servers for their users given that we know they will always use the same one? Something like consistent hashing? Thanks!
