Routing Failures

1. Service Unavailability

If the API Gateway is the only entry point for clients to access the microservices, then the entire system may become unavailable. Clients won’t be able to send requests to the microservices, leading to service disruptions....

2. Routing Failures

If the API Gateway is responsible for routing requests to different microservices, then routing failures may occur. Clients may experience delays or errors when trying to access specific endpoints or services....

3. Authentication and Authorization Issues

If the API Gateway is responsible for authentication and authorization, then clients may not be able to authenticate or access protected resources. This can lead to security vulnerabilities or unauthorized access to sensitive data....

4. Rate Limiting and Throttling Failures

If the API Gateway is enforcing rate limiting or throttling policies, then these policies may not be applied correctly. This can lead to an increase in requests to the microservices, potentially causing performance issues or service degradation....

5. Monitoring and Logging Loss

If the API Gateway is responsible for collecting metrics and logs, then the system may lose visibility into the performance and usage of the APIs. This can make it difficult to diagnose and troubleshoot issues in the system....
