Building Stateful Clustered Microservices with Java, Actors, and Kubernetes

Explore the world of stateful clustered microservices in this 57-minute Devoxx conference talk. Dive into building resilient systems using Java, Actors, and Kubernetes. Learn how the actor model provides a new approach to developing distributed applications in the post-Kubernetes era. Discover the advantages of stateful architectures over traditional stateless approaches. Examine live demonstrations of actor-based microservices running in clustered Kubernetes environments. Gain insights into topics such as pods, visualizations, crop circles, resilience, reactive systems, and cluster actors. Understand the mechanics of distributed systems, JSON trees, cluster singletons, and core persistence. Investigate the relationship between Kubernetes and various projects, including a comic book example. Acquire practical knowledge on deploying and managing stateful microservices in Kubernetes, with discussions on sharding versus pods and the possibility of running such systems without Kubernetes.
