Service Orthographic

For those more interested in a mathematical approach to visualizing services, consider a pool of all services whereby a service type is an orthogonal plane to various domains with ranges of constraints. If we set the constraints to a particular value, then we could say that a service is locked down and is now a line within the service type plane as illustrated below.

I like this diagram as it clearly indicates that a service can span many domains not just the technological or application.
