Kong can easily expand horizontally by simply adding machine nodes. Inherited OpenResty's high performance and easy scalability. Kong is based on OpenResty and is a cloud-native, fast, scalable, and distributed Api gateway. Therefore, we can make a variety of Lua scripts that meet the gateway strategy we need, and build a high-performance gateway system based on it. It is used to conveniently build dynamic Web applications, Web services and dynamic gateways that can handle ultra-high concurrency and high scalability. OpenResty® is a high-performance web platform based on Nginx and Lua, which integrates a large number of sophisticated Lua libraries, third-party modules, and most of its dependencies. Speaking of Kong may be a little unfamiliar to everyone, let's first understand another kind of middleware-OpenResty. Today, let’s briefly introduce another option-Kong. Currently, the commonly used microservice gateways are zuul and gateway. External requests can access all internal REST API services by accessing this access point. The API gateway serves as the API aggregation point and unified access point of microservices scattered in various business systems. Based on these various objective requirements, a system similar to the comprehensive front-end system is produced. Sometimes it is even necessary to perform some intermediate operations such as security, load balancing, current limiting, fuse, grayscale, etc. In order to cross-platform, in order to unify the centralized management api, and in order not to expose Home service. In the microservice architecture, the system structure becomes very complicated due to the subdivision of the system and the service.
