Nginx Nginx High Performance Caching Webinar Information

eva2000 · Aug 26, 2016

Nginx folks reposted on their blog the Nginx High Performance Caching Webinar information presented by Owen Garrett (Head of Products at Nginx Inc) & Andrew Alexeev (Nginc Inc Co-Founder).

Owen Garrett: Thank you Andrew and folks, thank you very much for joining us for the next 45 or 50 minutes. I’ll talk through how NGINX functions with respect to content caching, we’ll look at some of the ways that you can improve performance, we’ll do a little bit of a deep dive into how content caching really works so that you’re equipped to debug and diagnose what’s happening within NGINX, and I’ll round up with some clever hints and tips to give you some really fine grained control over what NGINX does with content that can be cached.

All aiming towards the same core reasons, as Andrew described, to take away the burden from your upstream servers of generating repetitive content so they’re freed up to run the applications that your business really needs. Increase beyond those servers, giving your end users a better level of service and increasing the reliability of your service as a hole in the face of big spikes of traffic from the internet and, potentially, failures of upstream servers.
