Video description

Beginning with the basics, this course covers the core principles of microservices architecture, contrasting it with traditional monolithic structures to highlight its modern software development benefits. You'll learn the process of breaking down complex applications into manageable, modular services that can be developed, deployed, and scaled independently. As the course unfolds, you'll delve into the creation of microservices using Spring Boot, exploring its convention over configuration philosophy that speeds up development time without sacrificing power or flexibility. With Spring Cloud, master the management of your microservices ecosystem, covering service discovery with Netflix Eureka, client-side load balancing with Ribbon, and implementing API gateways for efficient service-to-service communication.

Advanced topics include ensuring microservices resilience with Resilience4J, where you'll tackle patterns like circuit breakers and bulkheads to design fault-tolerant systems. Gain hands-on experience with deploying microservices in containerized environments using Docker and orchestrating them with Kubernetes, preparing you for the cloud-native landscape.

By the end of this course, you will have a solid foundation in microservices, along with the skills to design, develop, and deploy microservices applications confidently.

What you will learn

  • Create and manage microservices using Spring Boot and Spring Cloud
  • Utilize Docker and Kubernetes for microservices deployment
  • Apply Spring Security for authentication and authorization
  • Understand and implement Eureka, Ribbon, Feign, and Hystrix
  • Configure and manage microservices with Spring Cloud Config
  • Enhance microservices with centralized logging and monitoring

Audience

This course is for individuals at both beginner and experienced levels who want to learn how to design and develop RESTful web services with Spring Boot, and design and develop microservices with Spring Cloud. Apart from this, enthusiasts who want to learn to build containers for microservices with Docker and orchestrate microservices with Kubernetes. The basic requirement for this course is the attitude to learn while having fun. This course is designed for students with zero experience with either of the technologies – Java, Spring Boot, Spring Cloud, Docker, and Kubernetes.
