Understanding API Gateway

An API Gateway serves as a bridge between clients and microservices, routing requests to the appropriate service while providing various ancillary functions. The primary responsibilities of an API Gateway include:

1. Routing: Directing incoming requests to the right microservice based on URL paths, headers, or other parameters.
2. Load Balancing: Distributing incoming traffic across multiple instances of a microservice.
3. Rate Limiting: Protecting services from being overwhelmed by limiting the number of requests a client can make in a specified time frame.
4. Authentication and Authorization: Ensuring that only authorized users can access certain services.
5. Request and Response Transformation: Modifying requests/responses for compliance with specific standards or application requirements.
6. Logging and Monitoring: Keeping track of API usage and performance to optimize the infrastructure.
