About The Main Thread

Welcome to The Main Thread — your strategic companion for navigating the evolving world of enterprise Java, software architecture, and AI-infused systems. Curated by Markus Eisele, a veteran technologist with over two decades of industry experience, this publication connects the core ideas shaping our field today with the innovations that will define it tomorrow.

Here, we go beyond frameworks. We explore the “why” behind your architectural choices, the “what if” of platform decisions, and the career implications of living at the intersection of Java, cloud, and intelligence.

Because in a world of increasing complexity, the main thread isn’t just a technical construct: It’s a mindset.

I work at IBM Research, where they believe in open minds as much as open source. I speak here in a personal capacity. Nothing I say represents IBM officially; it’s just me thinking out loud. German, candidly and independently.
