Representational State Transfer (REST) has gained widespread acceptance across the Web as a simpler alternative to SOAP- and Web Services Description Language (WSDL)-based Web services.
Key evidence of this shift in interface design is the adoption of REST by mainstream Web 2.0 service providers—including Yahoo, Google, and Facebook—who have deprecated or passed on SOAP and WSDL-based interfaces in favor of an easier-to-use, resource-oriented model to expose their services
REST has emerged in the last few years alone as a predominant Web service design model.
REST web services have won the hearts of many working developers. For example, Amazon's web services have both SOAP and REST interfaces, and 85% of the usage is on the REST interface. Compared with other styles of web services, REST is easy to implement and has many highly desirable architectural properties: scalability, performance, security, reliability, and extensibility.
