Extending NGINX with (m)ruby

NGINX modules are typically written in C or Lua. Is there a performant way we can gain the elegance of Ruby without learning a new language? mRuby leads the way.

6. What can NGINX do?
7. What can NGINX do? • Load Balance – Route a request over multiple running versions of your application.
8. What can NGINX do? • Load Balance – Route a request over multiple running versions of your application. • Cache – Extremely efficient caching layer.
9. What can NGINX do? • Load Balance – Route a request over multiple running versions of your application. • Cache – Extremely efficient caching layer. • Resilience – Mitigate Denial of Service with rate limiting.
10. What can NGINX do? • Load Balance – Route a request over multiple running versions of your application. • Cache – Extremely efficient caching layer. • Resilience – Mitigate Denial of Service with rate limiting. • HTTPS – Attach an SSL cert (https://letsecure.me/)

What can NGINX do? • Load Balance – Route a request over multiple running versions of your application. • Cache – Extremely efficient caching layer. • Resilience – Mitigate Denial of Service with rate limiting. • HTTPS – Attach an SSL cert (https://letsecure.me/) • Service Routing – Complete a feature in a different application setup by a different team.

What can NGINX do? • Load Balance – Route a request over multiple running versions of your application. • Cache – Extremely efficient caching layer. • Resilience – Mitigate Denial of Service with rate limiting. • SSL – Serve HTTPS by attaching a certificate via NGINX • Service Routing – Complete a feature in a different application setup by a different team. • Logging – Track your 404s. Useful for understanding a new application stack by analyzing the request/responses.
