API Gateway

Category: infrastructure

A server that acts as a single point of entry for all client requests in a microservices architecture.

The Gateway is the "front desk." All incoming traffic goes through it. It handles rate limiting, authentication, load balancing, and routing. It allows you to change your internal services (like replacing your database) without the users ever noticing.

Common Examples

• We deployed an API gateway to centralize our security and rate limiting, simplifying the management of our multi-service ecosystem.
• The API gateway serves as the security perimeter, filtering malicious traffic before it ever touches our internal, private microservices.
