How Apache Pulsar helps Vivy empower people to take charge of their health

Kirill Merkushev, Head of Backend at Vivy, a digital healthcare platform, shares his company's adoption of Apache Pulsar for building a scalable event-driven system with an event-sourced architecture. They chose Pulsar over Kafka due to its operational advantages and compatibility with reactive, non-blocking libraries. Key features considered were tiered storage, flexible subscription models, authorization methods, and ease of setup. Merkushev advises organizations considering Pulsar to understand the different subscription models and experiment in a real environment. Future use cases for Vivy include cross-region replication and leveraging Pulsar functions for international setups.
