Transitioning from a monolithic application to a set of microservices can help increase performance and scalability, but it can also drastically increase complexity. Layers of inter-service network calls for add latency and an increasing risk of failure where previously only local function calls existed.
In my talk from Scala Days 2016 in New York, I spoke about how to tame this complexity using Apache Kafka and Reactive Streams to:
- Extract non-critical processing from the critical path of your application to reduce request latency
- Provide back-pressure to handle both slow and fast producers/consumers
- Maintain high availability, high performance, and reliable messaging
- Evolve message payloads while maintaining backwards and forwards compatibility.
