A QUICK CRASH COURSE ON STATEFUL VS STATELESS ARCHITECTURE

Summary from the TLDR Web Dev newsletter

Stateful architecture remembers client sessions and uses that history to inform operations, while stateless architecture processes each request independently, without any knowledge of previous interactions. Stateful systems have a better user experience and simpler client logic but have complex scaling and failure recovery challenges. On the other hand, stateless systems scale horizontally easily and are resilient, but require heavier requests and potentially more client complexity.
