Intermediate+ Beyond the Monolith: Designing an Event-Driven Platform Across Continents
What happens when a successful monolith needs to evolve into a platform capable of serving users across continents?
This talk follows the transformation from a region-bound, synchronously connected architecture toward an event-driven platform built around domain boundaries, business events, sagas, and globally distributed read models.
We will explore an architecture in which writes remain centralized while reads are served closer to users through regional projections. Along the way, we will examine the practical consequences of this model: eventual consistency, delayed and out-of-order events, retries, idempotency, data freshness, partial failures, and recovery.
The technical architecture is only part of the challenge. Moving beyond the monolith also requires dozens of teams to change how they design services, publish events, model data, and reason about failure.
Rather than presenting a perfect final architecture, this is a practical account of the decisions, trade-offs, and lessons involved in building an event-driven platform across continents.
