One.APIGateway h2>

API gateway, namely API Gateway, is a large In a distributed system, a barrier designed to protect internal services can provide high-performance and high-availability API hosting services to help service developers provide services to the outside world conveniently Instead of considering issues such as security control, flow control, and audit logs, unified security authentication, flow control, audit logs, black and white lists, etc. are implemented at the gateway layer. The next layer of the gateway is the internal service, and the internal service only needs to develop and pay attention to the realization of specific business. The gateway can provide main functions such as API publishing, management, and maintenance. Developers only need a simple configuration operation to publish the services they have developed, and at the same time put them under the protection of the gateway.

Second,kongIntroduction strong>

Kong is a model based on The Nginx_Lua module is highly available and easy to expand. The API Gateway project open sourced by Mashape. Since Kong is based on Nginx, it can expand multiple Kong horizontally The server, through the front load balancing configuration, evenly distributes the requests to each Server to respond to a large number of network requests.

Kong There are three main components:

    < li class="li6">Kong Server : server based on nginx, used to receiveAPIRequest.
  • Apache Cassandra/PostgreSQL : Used to store operation data.
  • Kong dashboard: Officially recommended UI management tool. Of course, you can also use restfull to manage admin api.

Kong uses a plug-in mechanism for function customization. The set of plug-ins (may be 0 or n) is in API is executed during the life cycle of the request and response cycle. The plug-in is written in Lua, and there are currently several basic functions: HTTP Basic authentication, key authentication, CORS ( Cross-origin Resource Sharing, cross-domain resource sharing), TCP, UDP, file logs, API request current limit, request forwarding, and nginx monitoring.
