Whenever something has gone seriously wrong for me in production caching has been at the root of it. Live Q&A with Julian Assange almost brought the site down? Caching fail. Servers can't cope with traffic about a new woolly rat? Caching fail. Half the site is showing sorry pages? Caching fail. This talk will use these disasters to explain why the simplest caching is always the best.

Your rails app is slow. Even after memory caching, optimizing queries, and adding servers the problem persists, killing your user experience. You’ve heard of services called "Content Delivery Networks" (CDNs), that could help, but they only seem to work with static content. Worry not, for there is a solution: dynamic content caching at the edge. In this talk, we explain how CDNs can be used to accelerate dynamic rails applications.
We will cover:

What is Caching?
What are CDNs?
What is Dynamic Caching?
Instant Purging
Surrogate-Control headers
Key Based Purging
A Rails Plugin for dynamic caching integration

You'll leave with:

A deep understanding of how caching and content delivery networks actually work. Understand recent innovations in CDN technology; things that enable edge caching dynamic content. Understand how rails plugins can be used to easily add dynamic edge caching functionality to your app. Gain insight into how to hook things into rails with plugins.

Snappiness is an important key for any successful webpage. Most companies try to achieve responsive webshops by scaling their hardware big time. But Rails in combination with Nginx, Memcached and Redis is the key to deliver webpages very fast with a minimal amount of hardware. This talk will start with the basics of DHH's russian doll idea but will raise the bar than quite a bit. How can we combine fragment caching, page caching and HTTP caching to deliver personalized webshop pages for logged in users? How much brain can be delegated to Redis or the Webbrowser? Harddrive space is cheap. So use it! You'll get to know how to plan your data structure and where to use Memcached vs. Redis. Include the cache in the beginning of your development and not in the end. To make things a bit more interesting everything is replayed on a Raspberry Pi to show how much difference intelligent caching can make on any hardware. Save big time and get more clients with a faster web application!

Most of us have some form of cache anxiety. We’re good at caching static content like images and scripts, but taking the next step - caching dynamic and user-specific content - is confusing and often requires a leap of faith. In this talk you’ll learn new and old strategies for caching dynamic content, HTTP performance rules to live by, and a better understanding of how to accelerate any application. This is just what the doctor ordered: a prescription for cache money.
