OpenResty (also known as ngx_openresty)

OpenResty is a high-end software based on Nginx and Lua A high-performance web platform that integrates a large number of sophisticated Lua libraries, third-party modules and most dependencies.

Used to easily build dynamic web applications, web services and dynamic gateways that can handle ultra-high concurrency and high scalability.

OpenResty effectively turns Nginx into a powerful universal web application platform by bringing together various well-designed Nginx modules (mainly developed independently by the OpenResty team). In this way, web developers and system engineers can use the Lua scripting language to mobilize various C and Lua modules supported by Nginx to quickly construct a high-performance web application system capable of handling more than 10K or even 1000K single-machine concurrent connections.

The goal of OpenResty is to let your Web service run directly inside the Nginx service, making full use of Nginx's non-blocking I/O model, not only for HTTP client requests, but also for remote backends Such as MySQL, PostgreSQL, Memcached and Redis all provide consistent high-performance response.
