Load balancers normally distribute requests across multiple interchangeable application instances. This works best when any healthy instance can process any request. Problems appear when an application stores user-specific state locally and later requests must return to the same server.

Horizontal scaling becomes significantly easier when application instances are interchangeable. A request can reach any healthy instance, failed instances can disappear without losing business state, and new capacity can join the fleet without synchronizing local files or sessions.
