Learn to implement SpringBoot based Microservices and RESTful API’s architecture from scratch in a practical step by step approach.

Microservices architecture has many advantages like:

  • Improved productivity

  • Better resiliency

  • Increased scalability

  • Continuous integration/continuous delivery (CI/CD)

  • Optimize business functionality

  • and many more

    We will be implementing many important concepts of microservices architecture like

    • Spring Cloud Config Server

    • Spring Cloud Bus

    • Spring Cloud Netflix Eureka

    • Spring Cloud Circuit Breaker

    • Spring Cloud Sleuth

    • Spring Cloud Gateway

    • Spring Cloud Stream

      We will be creating many springboot projects from scratch  from spring initializer, some of the microservice will be based on mongodb and some will work with mysql database.
