By mid-2013, I noticed a growing conversation in engineering circles about "microservices." The core idea wasn’t entirely new—modular systems, independent deployments, and domain ownership—but the momentum felt different this time.
It became clear that microservices were not just about splitting codebases. They were about evolving team structures, operational independence, and resilience strategies.
What resonated with me:
- Services need strong boundaries, not just APIs.
- Without automation and observability, microservices turn into distributed chaos.
- Start with modular monoliths if the team/process isn't ready yet.
These lessons shaped how I approached system boundaries for years to come.
