Course Outline: Spring Cloud

Course Summary

This comprehensive Spring Cloud course is designed to provide participants with the knowledge and skills necessary to effectively design, implement, and manage microservices architectures using Spring Cloud. The course starts with an introduction to cloud computing, microservices, and Spring Cloud, followed by practical setup and configuration of the Spring Cloud environment.

Participants will learn to implement service discovery with Eureka, client-side load balancing with Ribbon, and create API Gateways using Zuul and Spring Cloud Gateway. The course covers centralized configuration management with Spring Cloud Config, distributed tracing with Spring Cloud Sleuth and Zipkin, and resilience with Netflix Hystrix.

In addition, the course covers messaging with Spring Cloud Stream, security with Spring Cloud Security, and effective deployment and monitoring strategies. Real-world case studies and hands-on projects are integrated into the course to provide practical experience.

By the end of the course, participants will be equipped with the necessary skills to build and manage scalable, resilient, and secure microservices architectures using Spring Cloud.
