Modern systems are built on layers of abstraction.

Infrastructure as Code, managed services, reusable modules, and platform tooling allow us to move fast and build complex systems quickly. And most of the time, everything works.

Until something breaks.

At that point, a simple question becomes surprisingly difficult to answer:
How does this system actually work?

In many environments, no single person understands the full picture. Components are deployed from templates, connected through abstractions, and operated by different teams. When failures occur, troubleshooting becomes slow, uncertain, and sometimes guesswork.

In this lightning talk, I’ll explore what happens when systems become too abstract to understand, and why the real risk is not just insecure infrastructure, but systems that are so complex that troubleshooting requires expertise most teams don’t have.

Because when things fail, someone still needs to understand what was built.
