What is API Gateway?

It is a central entrance gate that meets all requests from the outside world, directs them to the right places and performs security checks.

Overview

Modern applications consist of many different parts. API Gateway is like a traffic cop standing in front of all these pieces. It receives the incoming request, checks who sent it, and forwards it to the relevant service.

Analogy: It is like the reception of a large company; All visitors come here first, their registration is made and it is determined which department they will go to.

How it works

It monitors incoming traffic, ensures security, restricts requests if necessary, and returns the results to the user.

Where it is used

It is used in large software systems with microservice architecture.

Commonly confused with

It is not just a router; It also undertakes security and management duties.

Frequently asked questions

Why is this needed?
