The Importance of Minimizing Downtime

Open resty is an open source version of NGINX that has certain extensions enabled, one of them being Lua extensions. If you're using open resty with Lua, you can actually script a solution to where instead of having those requests be served as like a 502 back end because it's down, you can have NGINX queue those requests up in order. And then when your application comes back up, it is going to release those items from the queue and just serve them as if it's basically zero downtime.
