Introduction
Welcome, dear reader, to the world of microservices! 🌟 Whether you're a tech enthusiast, a curious learner, or a seasoned developer, we invite you to embark on this exciting journey with us as we explore the captivating realm of microservices architecture. Together, we'll unravel the intricacies of this revolutionary approach to software development and understand its profound impact on modern applications. So, let's dive in and discover how microservices are reshaping the future of software engineering! 🚀📚🔍
Discover our project series building a robust banking system with four core services:
👤 User Service: We'll begin by exploring how to register users with the banking system and manage their information efficiently. You'll learn how to retrieve user details using unique IDs and account IDs, as well as how to modify user information based on their requests.
💼 Account Service: Next, we'll venture into the world of account management. We'll show you how to create and update different types of bank accounts, allowing users to have full control over their financial profiles. We'll also cover the account closing process and how to retrieve account details and transaction history.
💸 Fund Transfer Service: One of the most critical aspects of any banking system is the ability to transfer funds securely and swiftly. We'll guide you through the creation of endpoints that facilitate fund transfers between accounts. You'll also learn how to access comprehensive details of all fund transfers and dive deep into the specifics of particular transfers.
💳 Transaction Service: Last but not least, we'll explore the core of financial transactions. We'll help you build endpoints to retrieve all transactions made by an account, understand the nitty-gritty details of individual transactions, and enable users to make their financial transactions, such as deposits and withdrawals.
Other components that are present in the project:
🔍 Service Registry: Think of it as your microservices' address book. Services register themselves, making it easy for others to discover and connect with them
🚀 API Gateway: It's like the grand entrance to your microservices world. It handles routing, load balancing, security, and more, simplifying how clients access your services.
🔒 Keycloak Integration: Keycloak is your guardian angel, providing user authentication, authorization, and security. It ensures only the right users access your services while streamlining user management.
💾 Databases: Databases are your data vaults. They store and manage information for your microservices, whether it's structured data (SQL), flexible documents (NoSQL), or lightning-fast in-memory storage.
📚 Swagger Documentation: Swagger is your friendly librarian. It creates clear, interactive API documentation, so developers and users easily understand and work with your services.
Together, these components help you build a robust, secure, and well-documented microservices ecosystem, making management, scaling, and maintenance a breeze. 🛠️🌐📖🏦🔐
