REST web services
REST has become one of the most important technologies for stateless communications between devices. Due to the lightweight and stateless nature of the REST base services, its importance is likely to continue to grow as more devices are connected to the Internet.
REST is an architecture style for designing networked applications. The idea behind REST is instead of using complex mechanisms, such as SOAP or CORBA to communicate between devices, we use simple HTTP requests for the communication. While, in theory, REST is not dependent on the Internet protocols, it is almost always implemented using them.
