Course description
This comprehensive course provides a deep dive into microservice architecture development using Java, starting with core principles and characteristics of microservices. We cover vital aspects such as splitting an application into microservices, modeling and communication, exploring decomposition strategies, synchronous / asynchronous communication methods including REST, gRPC and messaging with Kafka.
The course also delves into data management complexities, addressing different persistence strategies, distributed database principles, and transaction management. It includes hands-on sessions on deployment, focusing on Docker and Kubernetes, plus exploring Service Mesh using Istio. By the end of the course, learners will have gained thorough expertise in developing, managing, and scaling microservices effectively.
