Evolutionary architecture

Architecture is becoming much less monolithic and static. According to Neal Ford and Rebecca Parsons of ThoughtWorks, “The software universe exists in a state of constant flux; it is dynamic rather than static. Architecture isn’t an equation but rather a snapshot of an ongoing process.” Take a look at how architectures, like microservices and serverless, are necessary in the time of continuous development and delivery.

If you still use large up-front design phases, you'll likely encounter problems with your design as you implement. The solution is to build around a domain-focused metaphor that allows for incremental changes while maintaining coherence throughout. Allen Holub demonstrates how to develop an effective and coherent architecture incrementally as the code evolves. Read more.
