A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Build the skills to design, develop, and secure scalable microservices using Spring Boot and Spring Cloud. This course equips learners with a practical understanding of RESTful web services, API architecture, and the essential tools required to create robust backend solutions in Java. Whether you're new to microservices or seeking a structured foundation, this course provides the hands-on knowledge to get you started confidently. You’ll begin with an introduction to microservices architecture and how Spring Boot simplifies development. Then, you'll explore foundational concepts like installing the Java development environment, understanding SOAP vs REST, and learning how to build and expose RESTful APIs. From there, you’ll incrementally develop a complete REST API with advanced features including versioning, filtering, error handling, Swagger documentation, and authentication using Spring Security. The final sections dive deeper into microservices concepts, connecting your services with relational databases using JPA, Hibernate, and MySQL, and implementing scalable microservice patterns. You’ll also explore tools like Docker, HAL Explorer, and Actuator for deployment, monitoring, and exploration. This course is designed for developers with basic Java knowledge who want to learn backend API development and microservices design. It is ideal for aspiring full-stack developers, backend engineers, and system architects. A working knowledge of object-oriented programming is recommended. This is an intermediate-level course. By the end of the course, you will be able to build REST APIs with Spring Boot, integrate them with databases, implement microservice architecture with Spring Cloud, and deploy scalable, secure applications with confidence.

In this module, we will explore the essential concepts of microservices architecture and how to get started with building microservices using Spring Boot and Spring Cloud. You will also learn how to install and configure your development environment to kickstart your journey into microservices development. By the end of this module, you'll have a solid foundation for creating scalable, production-ready applications.

Frequently asked questions

This course provides a comprehensive introduction to building and understanding microservices and REST APIs using Spring Boot and Spring Cloud. It begins with the fundamentals of web services and progresses to hands-on implementation of RESTful APIs, database integration, authentication, and microservices architecture, equipping learners with the skills to design scalable, maintainable, and production-ready applications.

Microservices are a software architectural style that structures an application as a collection of loosely coupled, independently deployable services. REST APIs (Representational State Transfer Application Programming Interfaces) enable communication between these services over the web. Together, they form the backbone of modern, cloud-native applications, providing scalability, flexibility, and resilience in distributed systems—skills highly sought after in today’s software development landscape.

After completing this course, you will be able to design and build RESTful APIs using Spring Boot, implement CRUD operations, handle exceptions, apply versioning, and add authentication with Spring Security. You’ll also gain practical experience connecting APIs to databases using JPA, Hibernate, and MySQL, documenting APIs with Swagger, and developing microservices that can be deployed and scaled using Spring Cloud.

To get the most out of this course, learners should have a basic understanding of Java programming and object-oriented concepts. Familiarity with fundamental web development principles and databases will be helpful, but the course provides setup guidance, including installing Java, Eclipse IDE, and configuring your environment for Spring Boot development.

This course is ideal for Java developers, software engineers, and students who want to transition into backend or microservices development. It also suits professionals who wish to deepen their understanding of RESTful API design and implementation or those seeking to modernize existing monolithic systems using microservices architecture.

The course contains approximately 7 hours of video content. Depending on your pace and practice time, it can be completed comfortably within one to two weeks. Learners are encouraged to follow along with the hands-on exercises to reinforce their understanding and build real-world coding experience.

Yes, the course balances theory with practical implementation. You’ll start by understanding core concepts like web services, REST, and microservices, then move on to building, testing, and deploying functional APIs and microservices with Spring Boot and Spring Cloud, ensuring both conceptual clarity and applied proficiency.

This is a standalone course designed to give you a complete, self-contained foundation in microservices and REST API development with Spring Boot, without requiring additional modules or prerequisites.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
