Representational State Transfer (REST) is an architectural style for designing networked applications. It relies on a stateless, client-server communication model, typically using HTTP, to enable scalable and flexible interaction between systems through standard methods like GET, POST, PUT, and DELETE.
What are the principles of REST?
Principles of REST include statelessness, client-server architecture, cacheability, uniform interface, layered system, and code on demand (optional), ensuring scalability and simplicity in web services design.
How does REST improve scalability?
REST improves scalability by enforcing stateless communication, allowing servers to quickly handle multiple requests without maintaining client state, and by enabling load balancing and caching mechanisms.
What are common use cases for REST?
Common use cases for REST include web APIs, microservices communication, and client-server interactions in web and mobile applications, due to its simplicity, scalability, and wide adoption.
