Exploring Stateful Microservices in the Cloud Native World

Explore the intricacies of stateful microservices in cloud-native environments through this informative conference talk. Delve into the challenges of architecting systems with microservice and REST API endpoints, examining the pros and cons of various solutions. Investigate whether state should be held in server-side components or externally, and challenge the notion that stateless containers are always the best practice for cloud-native systems. Learn about the fundamentals of cloud-native systems with stateful microservices built using Open Liberty and MicroProfile. Discover options for running applications in the JVM, including the Saga Programming Pattern and MicroProfile's Long-Running Action feature. Gain insights into leveraging concurrency for multi-core CPUs and clustered distributed systems. Compare stateful and stateless applications, understanding their complexities and risks, especially in distributed environments. Explore containerization and orchestration using Kubernetes for deployment. By the end of this talk, acquire a deeper understanding of handling state in cloud-native architectures and make informed decisions about technology stack choices for evolving systems.
