Using Code Examples

A statement or proposition which is regarded as being established, accepted, or self-evidently true.

Mathematicians create theories based on axioms, assumptions for things indisputably true. Software architects also build theories atop axioms, but the software world is, well, softer than mathematics: fundamental things continue to change at a rapid pace, including the axioms we base our theories upon.

The software development ecosystem exists in a constant state of dynamic equilibrium: while it exists in a balanced state at any given point in time, it exhibits dynamic behavior over the long term. A great modern example of the nature of this ecosystem follows the ascension of containerization and the attendant changes: tools like Kubernetes didn’t exist a decade ago, yet now entire software conferences exist to service its users. The software ecosystem changes chaotically: one small change causes another small change; when repeated hundreds of times, it generates a new ecosystem.

Architects have an important responsibility to question assumptions and axioms left over from previous eras. Many of the books about software architecture were written in an era that only barely resembles the current world. In fact, the authors believe that we must question fundamental axioms on a regular basis, in light of improved engineering practices, operational ecosystems, software development processes—everything that makes up the messy, dynamic equilibrium where architects and developers work each day.
