Build Reactive Microservices using Spring WebFlux/Spring Boot Course Overview

Build Reactive Microservices using Spring WebFlux/Spring Boot Course Overview

The "Build Reactive Microservices using Spring WebFlux/Spring Boot" course is designed to teach learners how to create responsive and non-blocking microservices using Spring WebFlux and Spring Boot. This course offers a deep dive into reactive programming principles, starting with why traditional Spring MVC may fall short in handling concurrent, high-load scenarios and progressing through the intricacies of reactive systems.

Learners will gain hands-on experience with Project Reactor, understanding its core types Flux and Mono, and learn how to develop and test non-blocking RESTful APIs. The course covers the execution model of Spring WebFlux and Netty, functioning of reactive databases with MongoDB, and client-side development using WebClient. Additionally, it addresses error handling in both annotated controllers and functional web approaches, and showcases the streaming of real-time data using server-sent events (SSE).

By incorporating key concepts like Reactive Streams Specification and reactive libraries, this course equips developers with the skills to build scalable and resilient microservices architectures, thereby enhancing their ability to manage modern, data-driven applications efficiently.
