Reactive Application

Reactive applications offer enhanced performance, scalability, and responsiveness by efficiently handling asynchronous I/O operations and providing a smoother user experience under varying workloads.

Reactive Tools Used

• Spring WebFlux: For building reactive web applications.
• R2DBC: For reactive database access.
• WebClient: For reactive HTTP client operations.

Microservices

Microservices architecture enables scalability, fault isolation, and technology diversity, allowing for independent development, deployment, and scaling of individual services, ultimately fostering agility and resilience in large-scale applications.

Microservices Tools Used

• Eureka Server: For managing service registration and handling service discovery.
• Eureka Client: For registering microservices with Eureka Server for discovery.
• Eureka Gateway: For routing requests to target microservices after contralized authentication.

Centralized Authentication with Spring Security and JwtToken

Centralized complete Jwt validation is performed in gateway microservice, using Spring Security and JWT Bearer tokens, before routing requests to target microservices.

Token presence is also checked in each target microservice for additional security measures and for extracting the logged-in user's role for a role-based security layer in rest controllers.
