It’s fun (for me anyway) to find ways to visually describe a complicated idea so anyone can understand. Service-Oriented Architecture (SOA) is one of those technology topics that benefits greatly from a visual spin. Below are some alternative sketches developed for the Forest Service as they work to build smart new apps for work and recreation.
From Wikipedia: Service-oriented architecture is less about how to modularize an application, and more about how to compose an application by integration of distributed, separately-maintained and deployed software components. It is enabled by technologies and standards that make it easier for components to communicate and cooperate over a network, especially an IP network.
