What is API Gateway?
An API Gateway serves as the system’s central point of management for APIs (Application Programming Interfaces). It is positioned in between client applications (such as web or mobile apps) and the backend services with which those clients communicate.
In the context of microservices and distributed systems, an API gateway is an essential part of modern software designs. In one or more applications, it acts as a single point of entry for clients to access a variety of services and APIs (Application Programming Interfaces). With a wide range of functions including routing, security, transformation, and management, an API gateway acts as a potent go-between for clients and backend services, enabling scalable, secure, and effective communication in distributed systems.
API Gateway Security in System Design
A server that serves as a middleman between clients and backend services is known as an API gateway. It serves as a hub through which clients (like web or mobile applications) can access information, features, or other services offered by different backend systems without having to communicate with them directly. A number of important factors need to be taken into account when building an API gateway’s security features within a system in order to protect the gateway and the underlying services it communicates with.
