  • Data structures vs. functions in the age of microservices

    Data structures vs. functions in the age of microservices

    The old wisdom of “data structures over functions” has stood the test of time for probably 50 years now. It states that long-term, a system is better built on sound data structures than functions. While functions may hide clumsy data structures for a while, when faced with evolution and new user needs, poor data structures…

  • Microservices vs. inner source

    Microservices vs. inner source

    I just listened to Eberhard Wolff’s BED-Con talk on microservice-based system architectures, which he prefers to call Independent Systems Architectures (ISA). One purpose of calling it ISA is to emphasize that there should be no common data model and no shared reusable libraries between microservices. Obviously, by discounting reuse, ISA may increase development speed short-term…

  • The design space for object creation

    The design space for object creation

    While preparing a session on (object-oriented) object creation for my Advanced Design and Programming course, I noticed that there are at least two major ways of looking at how to decide on how to create an object. The traditional way is a (still unwritten) pattern language that utilizes the classic Gang-of-Four object creational patterns (and…
