Exploring Stateful Microservices in the Cloud Native World
summary
Argues that cloud native does not require statelessness and shows concrete options: builds examples with Open Liberty and MicroProfile, uses MicroProfile LRA / Saga-style compensation for long running distributed transactions, demonstrates caching with JCache + Hazelcast, and contrasts Kafka with Apache Pulsar for cloud-native streaming and automatic partition rebalancing. Covers Kubernetes primitives like stateful sets, leader election, persistent volumes and session affinity, and explains when compensator services, event choreography or orchestration are actually needed.
