As developers, we love debating monoliths vs. microservices, event-driven vs. REST, serverless vs. Kubernetes. But beyond scalability, isolation, productivity, and other engineering trade-offs, there is a less glamorous, yet critical, dimension to these choices: cost.
In this talk, I’ll share real-world lessons from my experience building cloud-native systems and uncover the hidden price tags behind popular architectural styles. We'll break down the surprising costs of microservices, the savings (or not?) of monoliths, the trade-offs of serverless, and how an event-driven system can affect the budget.
This talk will give you a practical lens for evaluating architecture not just by performance or maintainability, but by the unexpected financial impact that comes with scale.
