In an IoT scheme, devices work in a client-server relationship. In that relationship, devices can act as clients, servers or both. Devices can act as a client and initiate contact with a directory, such as the CoRE Resource Directory, or another device.

Devices can also act in the capacity of an origin server or resource, such as to serve as a sensor, serving temperatures or other status indicators.Yet, as noted above, all client-server operations using REST should be stateless, and any state management that is required should happen on the client, not the server. That means all messages must contain all the information to process it, independent from previous messages.Two things have helped REST become popular with IoT developers.

Firstly, REST is already pervasive, well-understood and replicable. Secondly, because the data requested from resources in IoT tends to be simple, such as a sensor's current reading, and static, such as a manufacturer's device description, REST, which leverages the internet's HTTP, is a natural fit.Learn more about REST in the video below. The thing about SOAP is that a programmer typically never interacts with SOAP directly. Instead, you access a WSDL file and a Class library. You create some objects, set some properties, and invoke a method. I've been coding SOAP calls for years and have never, ever seen a SOAP XML stream.

The WSDL file makes SOAP very easy to use, and, in practice, you can do most of what you need to do with very little programming. Even better, SOAP returns objects, not JSON or XML, so on return from your SOAP call, you simply access object properties and methods.

I am seeing a lot of new web services are implemented using a REST style architecture these days rather than a SOAP one. Lets step back a second and explain what REST is.What is a REST Web Service?The acronym REST stands for Representational State Transfer, this basically means that each unique URL is a representation of some object. You can get the contents of that object using an HTTP GET, to delete it, you then might use a POST, PUT, or DELETE to modify the object (in practice most of the services use a POST for this).
