This is a beginner-friendly path into RESTful microservices, built with Spring Boot and Spring Cloud and deployed both locally and inside Docker containers on AWS EC2. You'll go from a single service running on your machine to a small distributed system running across multiple cloud instances.

Core Building Blocks

  • Eureka for service discovery and a Zuul API gateway with load balancing
  • A Spring Cloud Config Server for centralized configuration
  • Spring Data JPA against both H2 (with its console) and a MySQL server
  • Spring Cloud Bus with RabbitMQ, and Spring Boot Actuator for monitoring

Security and Observability

You'll implement user login and registration with Spring Security and JWT, then move into distributed tracing with Sleuth and Zipkin and centralized logging with the ELK stack (Logstash, Elasticsearch, Kibana) — the tools that make a multi-service system debuggable in practice.

Getting It Into the Cloud

The course finishes by launching AWS EC2 Linux machines, installing Docker, building images, and running the microservices across several EC2 instances, using Postman and Spring Tool Suite along the way. Basic Java knowledge and access to a Mac are the only prerequisites.

Who teaches Spring Boot Microservices and Spring Cloud? Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.

Frequently asked questions

What prerequisites are required before enrolling in the course?
This course is designed for beginners, so no prior experience with microservices is necessary. However, familiarity with Java programming, as you will need to install the Java Platform (JDK), and basic understanding of RESTful services will be beneficial. The course covers the installation of necessary tools like Postman HTTP Client and Spring Tool Suite, which are essential for development.
What projects will I be able to build by the end of this course?
By the end of the course, you will be able to build several key components of a microservices architecture, including RESTful Microservices, Eureka Discovery Service, Zuul API Gateway, and a Load Balancer. You will also implement a Spring Cloud Config Server and integrate security features such as user authentication and authorization using Spring Security and JWT.
Who is the target audience for this course?
The course is targeted at beginners who are eager to learn about building and managing RESTful Microservices using Spring Boot and Spring Cloud. It is suitable for individuals interested in understanding microservices architecture and those looking to deploy applications in Docker Containers on AWS EC2 Linux machines.
How does the course depth and scope compare to similar courses?
This course provides a comprehensive introduction to building microservices with Spring Boot and Spring Cloud, covering topics from setting up a development environment to deploying applications on AWS. With 226 lessons, it offers detailed instruction on tools like Eureka Discovery Service and Zuul API Gateway, making it a thorough choice for beginners.
What specific tools and platforms will I learn to use during the course?
The course covers a range of tools and platforms, including Spring Boot, Spring Cloud, Rabbit MQ, and Spring Cloud Bus. You will learn to use Postman for HTTP requests, Spring Tool Suite for development, and deploy applications within Docker Containers on AWS EC2 Linux machines. Additionally, data management with Spring Data JPA, H2 in-memory databases, and MySQL is addressed.
What topics are not covered in this course?
While the course provides a robust foundation in microservices with Spring Boot and Spring Cloud, it does not cover advanced topics like Kubernetes orchestration or deep dives into cloud-native patterns beyond AWS EC2 deployment. The focus remains on fundamental concepts and essential tools for a beginner-level understanding.
What is the expected time commitment for completing the course?
The course consists of 226 lessons, and while the exact runtime is not specified, prospective students should expect to dedicate a significant amount of time to cover all materials thoroughly. The course includes practical exercises and projects, which may require additional time for implementation and experimentation.
