Implementing the API Gateway pattern in a microservices-based application can significantly simplify the communication between clients and services. By centralizing access and providing additional functionalitie
Flow in API Gateway Client request:When a request is made from a client, the request first goes to the API gateway, and then the API gateway checks if requesting path and re-routes the request to the corresponding server or microservices. This diagram shows that all client request goes to ...
independent of the number of internal components.There are many reasons why we need an API gateway in the microservices architecture pattern, which are as given below:
Azure Application Gateway Azure API Management In a microservices architecture, a client might interact with more than one front-end service. Given this fact, how does a client know what endpoints to call? What happens when new services are introduced, or existing services are refactored? How ...
与面向对象设计的外观模式(Facade Pattern)相似,它封装底层系统架构细节,提供了一个单一的API入口点,称为API网关。 简而言之,它的行为就像API管理一样,但是不要将API管理与API Gateway混淆。 微服务的API网关 API网关的功能: 路由 网关封装了底层系统并与客户端分离,为客户端提供了与微服务系统进行通信的单个入口点...
This is where the API Gateway pattern comes in, as it insulates the consumers from all of these questions, by sitting in “front” of the microservices: Now back to our earlier questions: Where is each service located?Answer: the consumer doesn’t care. It just deals with the API Gateway...
Figure 2: API transformation function in an API gateway What Is the API Gateway Pattern? The API gateway pattern defines an approach where a server acts as a single-entry point for different types of clients — web, mobile, desktop — accessing a system comprising numerous microservices. The ...

of microservices. It's similar to theFacade patternfrom object-oriented design, but in this case, it's part of a distributed system. The API Gateway pattern is also sometimes known as the "backend for frontend" (BFF) because yo...
APIs are the connective tissue of modern software, linking everything from cloud workloads to IoT devices to AI-driven microservices. As a result, for organizations that juggle hybrid clouds, legacy systems and real-time data demands, the API gateway has evolved from a simple traffic router to ...
