Building Evolutionary Architectures: Principles and Practices

With technology, business models and business needs changing so rapidly, an adaptable architecture is critical to allow systems to cope with change. Historically, adaptability has been sought through anticipating the places where a system must be adaptable and through various architectural approaches. However, recent experiences have shown these approaches to be inadequate, at least as currently practiced. This talk presents some principles of evolutionary architecture that allow systems to respond to change without needing to predict the future. We then briefly describe approaches that realize these principles and discuss how these approaches support the adaptability of systems in an evolutionary way.
