Using Kong to configure Rate Limiting to a Simple Spring Boot REST API
Configuring Rate Limiting plugin in Kong to manage the frequency of requests sent to Simple API endpoints
In this article, we’ll build a Simple Spring Boot REST API named Simple API. This application features two endpoints: /with-no-limits
and /with-limits
. To prevent the second endpoint from being excessively accessed by users, we’ll set a rate control mechanism. However, instead of coding the rate limiting logic directly into the Simple API, we’ll make use of Kong.
Introduction
Kong is an open-source API gateway that simplifies API management, provides security, scalability, and analytics for APIs and microservices. It acts as a single entry point for clients to access backend services, offering features like authentication, load balancing, and custom plugins.
Both Kong and Simple API will be executed as Docker containers. However, the Simple API’s 8080
port won’t be exposed to the host machine, meaning users cannot access it directly. To circumvent this, we will utilize Kong as a gateway.
