API Gateway

The API Gateway serves as the entry point for all external requests, providing centralized control over API traffic and enhancing system security and performance. Key responsibilities of the API Gateway include:

1. Authentication and Authorization:

• Manages user authentication to verify credentials, ensuring only authorized users have access to resources.

• Controls user permissions, ensuring secure interactions between external systems and the platform.

2. Request Routing:

• Directs incoming API requests to the appropriate microservices, routing requests based on specific business logic or document management functions.

• Enables modular microservices architecture by allowing each service to operate independently, while still coordinating responses back to the requester.

3. Load Balancing and Throttling:

• Distributes incoming requests across multiple instances of microservices to prevent any one service from becoming a bottleneck, especially during high-traffic periods.

• Implements request throttling to manage the number of requests from users or systems, preventing overloads and maintaining consistent performance.

4. Error Handling and Monitoring

• Provides standardized error responses for issues such as failed authentication, unauthorized access, or exceeded rate limits.

• Monitors traffic, helping to detect unusual patterns or potential security threats in real-time.
