Best Practices for Deploying Confluent Kafka, Spring Boot & Distributed SQL Based Streaming Apps on Kubernetes

This summary highlights the challenges of deploying stateful streaming applications on Kubernetes, specifically those using Confluent Kafka, KSQL, Spring Boot, and distributed SQL databases like YugabyteDB. These apps are inherently stateful due to their need to handle continuous data streams, which poses scalability, reliability, and functional depth challenges. To address these challenges, the article outlines four best practices for deploying streaming apps on Kubernetes: using StatefulSets for stateful apps, low-latency storage, high data resilience, and high-performance networking. The article also provides a reference architecture for deploying an IoT fleet management app on K8S, showcasing the deployment of Confluent Kafka, KSQL, Spring Boot, and YugabyteDB in a Kubernetes environment.
