What you'll learn

  • Learn how to implement evolutionary architectures

Description

The software development ecosystem exists in a state of dynamic equilibrium, where any new tool, framework, or technique leads to disruption and the establishment of a new equilibrium. Predictability is impossible when the foundation architects plan against changes constantly in unexpected ways. Instead, prefer evolvability over predictability. For many years, software architecture was described as the “parts that are hard to change later.” But then microservices showed that if architects build evolvability into the architecture, change becomes easier. An evolutionary architecture supports incremental, guided change as a first principle across multiple dimensions. Neal Ford illustrates how to achieve evolutionary architectures and how to retrofit existing systems to support better evolution.

Drawing on concepts from his new book, Building Evolutionary Architectures, Neal investigates the family of software architectures that support evolutionary change and explains how to build evolvable systems. Understanding how to evolve architecture requires understanding how architectural dimensions interact; Neal describes how to achieve appropriate coupling between components and services. Incremental change is critical for the mechanics of evolution; Neal covers how to build engineering and DevOps practices to support continuous change. Uncontrolled evolution leads to undesirable side effects; Neal demonstrates how fitness functions build protective, testable scaffolding around critical parts to guide the architecture as it evolves.
