This is a story about Loggi, a logistics company that expanded rapidly and needed to adapt its systems to handle the growth. They moved from a monolithic architecture to an event-driven architecture using Apache Kafka and Confluent Cloud. This allowed them to scale their services, improve data analytics, and make their teams more productive. The key requirements for this new architecture were simplicity, scalability, transactional guarantees, and strong observability. Loggi learned that having a simple and straightforward design was crucial for user adoption and team productivity. They also realized the importance of observability, documentation, and fine-tuning for high-volume events. After two years in production, their event-driven architecture has been successful, enabling real-time data streaming and empowering teams to experiment and innovate without worrying about Kafka architecture.
