A simple Spring Boot project to understand the operation and communication of microservices.

Microservices added:

• Patient-Service: Handles all the CRUD operations for fetching, modifying, and deleting users.
• Billing-Service: Handles billing purposes for users.
• Api-Gateway: Handles all external requests to one point and then forwards those requests to the appropriate microservice, which improves security by not exposing all the internal ports to an outside request.
• Auth-Service: Handles the authorization of users to log in to the system by generating tokens using JWT.

Technologies and Dependencies Used:

• Java 21
• Spring Boot v3.4.1
• Docker
• gRPC
• Kakfa
• Spring Cloud
• Maven
