Lessons Learned From Working With 2,000 Event-Driven Microservices - Natan Silnitsky
Wix has a huge scale of event driven traffic. More than 70 billion Kafka business events per day.
Over the past few years Wix has made a gradual transition to an event-driven architecture for its 2,000 microservices. We have made mistakes along the way but have improved and learned a lot about how to make sure our production is still maintainable, performant and resilient.
In this talk you will hear about the lessons we learned including:
1. The importance of atomic operations for databases and events
2. Avoiding data consistency issues due to out-of-order and duplicate processing
3. Having essential events debugging and quick-fix tools in production
