REST Constraint #5: Embracing Layers for Flexibility and Scale
Building a reliable, scalable web application is no easy feat. The internet is unpredictable, traffic surges happen, and security threats lurk around every corner. That’s why REST includes the Layered System constraint—a design principle that structures applications into multiple layers, each handling a specific role. Whether it’s distributing traffic, securing data, or managing services, layering helps RESTful systems stay resilient and adaptable.
