Scale By the Bay 2020

Kafka is the bedrock of Wix's distributed microservices system. For the last 5 years we have learned a lot about how to successfully scale our event-driven architecture to roughly 1500 microservices, mostly written in Scala. We’ve managed to achieve higher decoupling and independence for our various services and dev teams that have very different use-cases while maintaining a single uniform infrastructure in place. Our Kafka infrastructure is called Greyhound and was recently completely re-written using ZIO. In this talk you will learn about 8 key decisions and steps you can take in order to safely scale-up your Kafka-based system. These include:
* How to increase dev velocity of event driven style code.
* How to optimize working with Kafka in polyglot setting
* How to support a growing amount of traffic and developers.
