Event-Driven

Introduction # In the landscape of 2025, distributed systems are the norm. We often reach for heavy-lifting tools like Kafka, RabbitMQ, or NATS JetStream immediately when we hear “message queue.” However, for many internal application workflows, micro-batching tasks, or decoupling services within a single monolith, these external dependencies introduce unnecessary latency, operational overhead, and serialization costs.

The era of the tightly coupled monolith is fading, but the challenge of distributed systems is rising. In 2025, building a backend isn’t just about handling HTTP requests; it’s about choreographing complex data flows asynchronously.

Introduction # It is 2026. The days of monolithic, 2,000-line controller methods in PHP are—or at least should be—long behind us. Yet, as we scale our applications to handle the traffic demands of the modern web, we often hit a wall. A user registers, and suddenly your application is trying to save to the database, send a welcome email, subscribe them to a newsletter, generate an invoice, and notify a Slack channel. If any one of those third-party services hangs, your user is left staring at a loading spinner.

Mastering Event-Driven Architecture with Go and Apache Kafka # In the landscape of modern backend development in 2025, the shift from monolithic, synchronous systems to decoupled, event-driven architectures (EDA) is not just a trend—it’s a necessity for scale. While HTTP REST and gRPC have their place, they introduce tight coupling and latency chains that can cripple high-throughput systems.
