real-time-ui-with-kafka-streams
Fast data arrives in real time and potentially high volume. Rapid processing, filtering and aggregation is required to ensure timely reaction and actual information in user interfaces. Doing so is a challenge, make this happen in a scalable and reliable fashion is even more interesting. This session introduces Apache Kafka as the scalable event bus that takes care of the events as they flow in and Kafka Streams for the streaming analytics. Both Java and Node applications are demonstrated that interact with Kafka and leverage Server Sent Events and WebSocket channels to update the Web UI in real time. User activity performed by the audience in the Web UI is processed by the Kafka powered back end and results in live updates on all clients.

lucasjellema/2019-fontys-business-and-IT-agility-through-microservice-architecture
Business and IT agility through microservice architecture powered by containers and cloud Evolving architectures, emerging technology and new cloud services enable new ways to address business challenges with IT solutions. Microservices architecture promises flexibility, scalability, and optimal use of compute resources. This lecture introduces the objectives that microservices are expected to realize and explains how microservices will do that. The lecture describes the key concepts – domain driven design, bounded context, events, statelessness and APIs. It discusses and demonstrates a real implementation of microservices using containers and Kubernetes. Students will do a hands-on with the Kubernetes platform – learning about the container orchestration features that allow microservices to be deployed, scaled, configured, failed over, and upgraded to new versions while maintaining proper routing and load balancing. Students will learn how to make use of Kubernetes for running multiple interacting containers executing applications written in the technology of their choice. The lectures discusses the service mesh and challenges with tracing and end to end monitoring. The relevance of events for decoupled collaboration is discussed and demonstrated. Concepts discussed include workflow choreography, the CQRS data(base) pattern for cross domain data sharing and serverless architecture.
