Introduction

The project showcases a microservices architecture, which is a distributed approach to building software systems. In this architecture, the application is divided into multiple loosely coupled services, each responsible for a specific set of functionalities. These services communicate with each other through APIs and message queues.

Architecture

The architecture of the project consists of the following components:

• Discovery Server: The discovery server, implemented using Eureka, is responsible for service discovery and registration. It allows services to locate and communicate with each other without prior knowledge of network topology.

• API Gateway: The API gateway, implemented using Spring Cloud Gateway, acts as a single entry point for clients to access various microservices. It provides routing, filtering, and load balancing functionalities, making it easier to manage and secure the system's APIs.

• Microservices: The project comprises multiple microservices, each responsible for specific business functions. These microservices communicate with each other via HTTP RESTful APIs.

• Databases: PostgreSQL databases are used to store persistent data for each microservice.

The application consists of several services:

• Akbank Service: Manages applications related to Akbank.
• Garanti Service: Manages applications related to Garanti.
• Kredinbizde Service: Core service managing user-related operations and integrating with Akbank and Garanti services.
• Notification Service: Handles notifications using RabbitMQ as a message broker.
