Om sesjonen

Architecture books teach you patterns. They don't teach you how to choose between them when you're under pressure, facing incomplete information, and living with real consequences.

In mission-critical systems, architectural decisions aren't just about code quality - they're about operational success. A poor choice doesn't just create technical debt; it can impact system availability, security posture, and the ability to respond when things go wrong.

This talk explores the reality of architectural decision-making in high-stakes environments through several real scenarios:
- A legacy system that needs modernization - rewrite or evolve?
- A performance vs. maintainability trade-off with no clear winner.
- A microservices migration with strict operational constraints.
- A critical dependency that stopped being maintained.
- An availability commitment that might not be achievable.

You'll leave with a framework for making better architectural decisions when the stakes are high and the right answer isn't obvious.

Passer for

Software architects, technical leads, developers, software engineers. How participants will benefit? They will leave with pattern recognition for architectural risk and red flags, techniques for making decisions with incomplete information, real examples of architecture decisions, outcomes and lessons learned from different situations. In terms of recommended experience, I would say that everyone is welcome to participate. It could be beneficial to have a basic understanding of common architectural patterns like monolith, microservices, layered architecture and distributed system concepts (high level is more than enough).
