Spring Framework and Microservices
MindCraft Backend Web Dev - Spring, and Microservices Lecture 8
Course by: MindCraft

In this detailed lecture, we dive into the Spring Framework and its application in building scalable microservices. This session will provide a comprehensive overview of how Spring integrates with microservices architecture, covering essential topics and practical implementations.

We start with an introduction to the Spring Framework and then explore various components including Spring JDBC for database operations, Spring MVC for building web applications, and Spring ORM for managing object-relational mapping. The lecture also covers Spring Data JPA for advanced data handling and RESTful web services using Spring Boot.

You'll learn how to create and manage projects with Spring Boot MVC and MongoDB, and delve into advanced topics like Spring AOP (Aspect-Oriented Programming) and Spring Security. The session then transitions to microservices concepts, cloud computing, and deployment strategies, including blue-green deployment and distinctions between cloud-native and cloud-ready applications.

Practical aspects include creating and running microservices, setting up Eureka Server for service discovery, using Feign for inter-service communication, and handling load balancing and API gateways to ensure effective microservices operation.
