Introduction to OpenResty XRay
is published.
OpenResty
is a full-fledged web platform that integrates our
enhanced version of the
Nginx
core, our enhanced version of
LuaJIT
, many carefully written Lua
libraries, lots of high quality
3rd-party Nginx modules
, and
most of their external dependencies. It is designed to help developers easily
build scalable web applications, web services, and dynamic web gateways.
By taking advantage of various well-designed
Nginx
modules (most
of which are developed by the OpenResty team themselves), OpenResty
effectively
turns the nginx server into a powerful web app server, in which the web developers
can use the Lua programming language to script various existing nginx C modules
and Lua modules and construct extremely high-performance web applications that
are capable to handle 10K ~ 1000K+ connections in a single box.
OpenResty
aims to run your server-side web app completely in the
Nginx
server,
leveraging
Nginx
's event model to do non-blocking I/O not only
with the HTTP clients, but also with remote backends like MySQL, PostgreSQL,
Memcached, and Redis.
Real-world applications of OpenResty
range from dynamic web portals and web
gateways, web application firewalls, web service platforms for mobile
apps/advertising/distributed storage/data analytics,
to full-fledged dynamic web applications and web sites. The hardware used to
run OpenResty
also ranges from very big metals to embedded devices with very
limited resources. It is not uncommon for our production users to serve billions
of requests daily for millions of active users with just a handful of machines.
OpenResty
is
not
an
Nginx
fork. It is a higher
level application and gateway platform using Nginx as a component.
Most of the patches applied to the
Nginx
core in OpenResty
have
already been submitted to the official
Nginx
team and most of
the patches submitted have also been accepted. We constantly import the latest
features and bug fixes from the official
Nginx
team, the official LuaJIT repository, and other sources.
