Step By Step Spring Boot Microservices and Cloud Deployment

🌟 Step By Step Spring Boot Microservices and Cloud Deployment 🌟

Course Headline: Dive into building robust, scalable microservices with Spring Boot, secure them with Spring Security, JWT, and deploy seamlessly to Heroku using Github, PostgreSQL, H2-Database, Hibernate, and Lombok.

Introduction: Hey there, future architects of modern cloud applications! 🚀

In this comprehensive course, we'll embark on a journey to construct a full-fledged product-ordering application using Spring Boot microservices. This isn't just any ordinary app; it's a real-world example that includes a user-friendly product list, shopping capabilities, and secure transaction logging. 🛍️💳

What We'll Build: Our project will revolve around three distinct microservices:

• Api Gateway: The central hub for all API requests, managing user authentication and routing to other services.
• Product Service: Dedicated to managing all CRUD operations related to products.
• Transaction Service: Responsible for recording each transaction made by customers. 📄

Microservices Architecture:

• Api Gateway: Acts as the entry point, handling user authentication and providing secure access to other services.
• Product Service: A service entirely focused on product management within our application ecosystem.
• Transaction Service: Specializes in recording transactional data, including purchase details like UserX bought ProductX on DateX. 📅

Security Measures: Spring Security and JWT tokens are at the core of our security strategy, ensuring all communications between microservices are secure. We'll also implement secure key tokens to safeguard inter-service interactions. 🔒

Database Choices: We've selected PostgreSQL for its robustness and H2Database for local development, both of which are compatible with Heroku deployments. These choices allow us to focus on the application logic without database deployment constraints. 🗂️

Networking with Retrofit: Our microservices will communicate using the Retrofit library, a reliable tool for handling RESTful API interactions in Android and Java programs. Retrofit simplifies networking code and makes our services more efficient. 🌐

Deployment on Heroku: Heroku offers a fantastic platform to deploy Spring Boot applications with ease. We'll configure our projects to be deployed via GitHub, ensuring that our codebase is always up-to-date and accessible. By the end of this course, you'll have a live application on production! 📫

Technologies Used:

• Spring Boot: The bedrock upon which we build fast and easily configurable applications.
• Spring Security: Ensures our application is secure from potential threats.
• Hibernate: Facilitates object-relational mapping, simplifying our interactions with databases.
• PostgreSQL & H2Database: Our chosen databases for production and development environments, respectively.
• Gradle: A powerful build automation tool that helps streamline the development process.
• Lombok: Helps reduce boilerplate code and enhances developer productivity. 🛠️
• Heroku & Github: Our deployment platforms, enabling us to deploy and version control our applications efficiently.

Testing with Postman: To ensure our services work as intended, we'll use Postman for thorough testing and debugging of our networking components. It's an essential tool in every developer's toolkit. ✅

Conclusion: This course will equip you with the knowledge and skills to create, deploy, and maintain microservices architecture applications using Spring Boot and other cutting-edge technologies. Get ready to join the ranks of professional developers who build and manage cloud-native applications! 🏆
