Building Evolvable Architectures
Until now, we’ve addressed the three primary aspects of evolutionary architecture — fitness functions, incremental change, and appropriate coupling — separately. Now we have enough context to tie them together.
Many of the concepts we discussed aren’t new ideas, but rather viewed through a new lens. For example, testing has existed for years, but not with the fitness function emphasis on architectural verification. Continuous Delivery defined the idea of deployment pipelines. Evolutionary architecture shows architects the real utility of that capability.
Many organizations pursue Continuous Delivery practices as a way to increase engineering efficiency for software development, a worthy goal in itself. However, we’re taking the next step, using those capabilities to create something more sophisticated — architectures that evolve with the real world.
So how can developers take advantage of these techniques on projects, both existing and new?
