Cloud Native Night March 2020, Mainz: Talk by Perry Krol (@perkrol, Confluent) === Please download slides if blurred! === Abstract: Proven approaches such as service-oriented and event-driven architectures are joined by newer techniques such as microservices, reactive architectures, DevOps, and stream processing. Many of these patterns are successful by themselves, but they provide a more holistic and compelling approach when applied together. In this session Confluent will provide insights how service-based architectures and stream processing tools such as Apache Kafka® can help you build business-critical systems. You will learn why streaming beats request-response based architectures in complex, contemporary use cases, and explain why replayable logs such as Kafka provide a backbone for both service communication and shared datasets. Based on these principles, we will explore how event collaboration and event sourcing patterns increase safety and recoverability with functional, event-driven approaches, apply patterns including Event Sourcing and CQRS, and how to build multi-team systems with microservices and SOA using patterns such as “inside out databases” and “event streams as a source of truth”.
