Pub/Sub is a messaging pattern. Event-Driven Architecture is an architectural discipline. Every EDA implementation may use Pub/Sub, but not every Pub/Sub implementation is truly Event-Driven Architecture. For many years, I would have agreed with the...

In today's digital enterprise, Event-Driven Architecture EDA has become a preferred architectural pattern for building scalable, loosely coupled, and real-time systems. By enabling applications to publish and subscribe to events independently, EDA pr...

⚡ EDA ≠ Just Pub/Sub: Building Flexible Request/Reply Journeys Through Event Choreography > 🚀 Exciting Update: Incredibly honored that this deep dive was selected for the HackerNoon Science Tech Brief within 12 hours of its original release! Sharin...

Compared with traditional queue-based messaging platforms, Kafka is primarily designed for event streaming. It excels at distributing data from producers to one or many consumers at massive scale. However, unlike many traditional messaging platforms,...

Hi everyone at CoderLegion. The leap from simple API wrappers to actual autonomous agents in production presents massive architectural challenges—especially when dealing with long-running tasks. I wanted to share a real-world demo of how we handle th...

> A practical guide to building reliable event-driven systems in Go using Apache Kafka. Learn how to implement tiered retry strategies with delayed reprocessing, route permanently failed messages to dead letter queues in Golang with Sarama. Prerequ...

Most Kafka “healthcare interoperability” examples are theoretical or focused on US/EU EHRs. I wanted to share a concrete case from a mid‑size hospital in Venezuela where we used Kafka as the event backbone between HIS, LIS and billing systems. Conte...

Project Overview In this example, we will build a simple advertisement platform. This platform will send a notification if the advertisement is created. The message queue is utilized as a buffer between the advertisement service and the notificatio...

In financial software, data does not just need to be correct — it needs to be provably correct. Regulators, auditors, and compliance teams do not take your word for it. They need an unbroken chain of evidence showing exactly what happened, when it ...

At 2:17 AM, the dashboard wasn’t moving. Transactions were still coming in, but the numbers on the screen were frozen. The system was running, but the data was already 10 minutes behind. At that scale, 10 minutes wasn’t just delay — it meant decisi...

In many architectures, the separation between database and application code introduces a dangerous gap where data integrity can fail. The application code is responsible for validation, but what if multiple services access the same data? This post e...
