Microservices Tutorial for Beginners
MindCraft Backend Web Dev - Spring, and Microservices Lecture 11
Course by: MindCraft

In this comprehensive lecture, we delve into the foundational concepts of microservices architecture and provide practical guidance on building and managing microservices using Spring Boot. This session is tailored for beginners and covers the essential aspects of creating, deploying, and managing microservices in a modern application environment.

We begin with an overview of what microservices are and their benefits over monolithic architecture. You will then learn how to start building microservices from scratch, including creating and running various services. The lecture covers the use of key components such as Eureka for service discovery, Feign for inter-service communication, and the implementation of load balancing and API Gateway for managing and routing requests.

By the end of this lecture, you will have a solid understanding of microservices architecture and hands-on experience in creating and integrating microservices within a Spring Boot ecosystem.
