SOA WS-* Approach

HTTP as transporter.

The comp-comp interface is a WSDL.

User Interface?

Testing: stub generation from a WSDL and lots of SOAP messages.

SOA loves XML.

An App Server everywhere.

Heavy.

Through the Web.

ROA REST Approach

HTTP as service platform!

The comp-comp interface is the URL.

The UI is the URL/browser.

Testing by typing a URL in your browser (doable?)

ROA loves JSON.

A Web Server everywhere.

Less heavy.

The WEB!

For an Internet of Things, SOA is not always the right approach:
