Core Concepts and Constraints
Understand the foundational principles of Representational State Transfer.
Part 1/3 — Advanced Theory & Mechanics
The architectural style known as REpresentational State Transfer (REST) was formalized by Roy Fielding in his 2000 doctoral dissertation, "Architectural Styles and the Design of Network-based Software Architectures," specifically within Chapter 5. Unlike traditional Remote Procedure Call (RPC) protocols such as SOAP (Simple Object Access Protocol) or XML-RPC, REST is not a protocol but a set of six derivation constraints applied to a distributed system's components, connectors, and data elements. The primary objective of these constraints is to improve latency, scalability, and the independence of deployment cycles in environments governed by the Hypertext Transfer Protocol (HTTP/1.1 and HTTP/2).
