Apache APISIX 是一个动态、实时、高性能的云原生 API 网关。它构建于 NGINX + ngx_lua 的技术基础之上,充分利用了 LuaJIT 所提供的强大性能。 [为什么 Apache APISIX 选择 NGINX+Lua 技术栈?](https://apisix.apache.org/zh/blog/2021/08/25/why-apache-apisix-chose-nginx-and-lua/)。

APISIX 主要分为两个部分:
1. APISIX 核心:包括 Lua 插件、多语言插件运行时(Plugin Runner)、Wasm 插件运行时等;
2. 功能丰富的各种内置插件:包括可观测性、安全、流量控制等。
APISIX 在其核心中,提供了路由匹配、负载均衡、服务发现、API 管理等重要功能,以及配置管理等基础性模块。除此之外,APISIX 插件运行时也包含其中,提供原生 Lua 插件的运行框架和多语言插件的运行框架,以及实验性的 Wasm 插件运行时等。APISIX 多语言插件运行时提供多种开发语言的支持,比如 GolangJavaPythonJS 等。
APISIX 目前也内置了各类插件,覆盖了 API 网关的各种领域,如认证鉴权、安全、可观测性、流量管理、多协议接入等。当前 APISIX 内置的插件使用原生 Lua 实现,关于各个插件的介绍与使用方式,可以查看相关[插件文档](https://apisix.apache.org/docs/apisix/plugins/batch-requests)。
