In the 80s and 90s, organizations grew with lots of different platforms that were sometimes doing the same things. Service oriented architecture was about how to maximize the investment in our internal IT estate. Now people started to think about right-side service, microservice. Then there's also the idea of modular monoliths. This really seems like a complex way to build systems. And I don't think anyone's ever said that you shouldn't build structured models once you go past a certain scale.
“Spend some time looking at the system in which you work. Understand how the work is working. Understand how flow is for your organization. And then you can work to optimize that."
James Lewis is a Director at ThoughtWorks and a pioneer of microservice architecture. In this episode, we went back memory lane to the time when James first coined and popularized the microservice architecture. James described his definition of a microservice and its important characteristics. He also shared the recent microservice evolution, including the swing between microservice and monolith. In the second half, James shared his insights from complexity science related to different scaling patterns. Particularly, he explained how different hierarchy types can affect an organization’s growth rate. Towards the end, James gave some tips on how organization can detect signs of suboptimal growth and what we can do to maintain organizational agility.
