NGINX + Free SSL Certificates


NGINX is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. NGINX is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.

NGINX is one of a handful of servers written to address the C10K problem. Unlike traditional servers, NGINX doesn’t rely on threads to handle requests. Instead it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but more importantly, predictable amounts of memory under load. Even if you don’t expect to handle thousands of simultaneous requests, you can still benefit from NGINX’s high-performance and small memory footprint. NGINX scales in all directions: from the smallest VPS all the way up to large clusters of servers.

NGINX powers several high-visibility sites, such as Netflix, Hulu, Pinterest, CloudFlare, Airbnb,, GitHub, SoundCloud, Zynga, Eventbrite, Zappos, Media Temple, Heroku, RightScale, Engine Yard, MaxCDN and many others.

We recommend using NGINX to proxy requests for JIRA or Confluence running in a standard Tomcat container. Putting JIRA or Confluence behind a NGINX proxy server will give you the option of hiding the port numbers.

Free SSL Certificates using Let’s Encrypt

To enable HTTPS on your website, you need to get a certificate (a type of file) from a Certificate Authority (CA). Let’s Encrypt is a CA. In order to get a certificate for your website’s domain from Let’s Encrypt, you have to demonstrate control over the domain. With Let’s Encrypt, you do this using software that uses the ACME protocol, which typically runs on your web host.

We will configure HTTPS for your Atlassian web server with automatic certificate renewals every 90 days.
