What is nginx?

nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. According to Netcraft nginx served or proxied 30.46% of the top million busiest sites in Jan 2018.

What is Pow?

Pow is a zero-configuration Rack server for Mac OS X. It makes developing Rails and Rack applications as frictionless as possible. You can install it in ten seconds and have your first app up and running in under a minute. No mucking around with /etc/hosts, no compiling Apache modules, no editing configuration files or installing preference panes. And running multiple apps with multiple versions of Ruby is trivial.

What is Puma?

Unlike other Ruby Webservers, Puma was built for speed and parallelism. Puma is a small library that provides a very fast and concurrent HTTP 1.1 server for Ruby web applications.

          HAProxy (High Availability Proxy) is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
          lighttpd has a very low memory footprint compared to other webservers and takes care of cpu-load. Its advanced feature-set (FastCGI, CGI, Auth, Output-Compression, URL-Rewriting and many more) make lighttpd the perfect webserver-software for every server that suffers load problems.
          A modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with your existing infrastructure components and configures itself automatically and dynamically.
          Caddy is a production-ready open-source web server that is fast, easy to use, and makes you more productive. HTTP/2 and HTTPS by default
          Originally built at Lyft, Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and “universal data plane” designed for large microservice “service mesh” architectures.

          The original API performed a synchronous Nginx reload after provisioning a zone, which often took up to 30 seconds or longer. While important, this step shouldn’t block the response to the user (or API) that a new zone has been created, or block subsequent requests to adjust the zone. With the new API, an independent worker reloads Nginx configurations based on zone modifications.It’s like ordering a product online: don’t pause the purchase process until the product’s been shipped. Say the order has been created, and you can still cancel or modify shipping information. Meanwhile, the remaining steps are being handled behind the scenes. In our case, the zone provision happens instantly, and you can see the result in your control panel or API. Behind the scenes, the zone will be serving traffic within a minute.

          Nginx serves as the loadbalancer, router and SSL terminator of As one of our app server nodes is spun up, an Ansible orchestration script adds the new node dynamically to the nginx loadbalancer config which is then reloaded for a zero downtime seamless rolling deployment. By putting nginx in front or whatever web and API servers you might have, you gain a ton of flexibility. While previously I've cobbled together HAProxy and Stun as a poor man's loadbalancer, nginx just does a much better job and is far simpler in the long run.

          Used nginx as exactly what it is great for: serving static content in a cache-friendly, load balanced manner.

          It is exclusively for production web page hosting, we don't use nginx internally, only on the public-facing versions of static sites / Angular & Backbone/Marionette applications.

          We use NGINX both as reverse HTTP proxy and also as a SMTP proxy, to handle incoming email.

          We previously handled incoming email with Mandrill, and then later with AWS SES. Handling incoming email yourself is not that much more difficult and saves quite a bit on operational costs.

          NGINX sits in front of all of our web servers. It is fantastic at load balancing traffic as well as serving as a cache at times when under massive load. It's a robust tool that we're happy to have at the front lines of all Wirkn web apps.

          Pow is what we use for development on our local machines. It's easy to setup, and easy to maintain since it also eliminates the need for maintaining a /etc/hosts file.
