Title

Description

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.

The video titled 'Edge Caching Dynamic Rails Apps' by Michael May at GoRuCo 2014 explores the effectiveness of Content Delivery Networks (CDNs) in optimizing the performance of dynamic Ruby on Rails applications. In light of persistent performance issues even after implementing traditional caching methods, the talk emphasizes the potential of edge caching as a solution.

Key points discussed include:
- **Basics of Caching**: Caching is crucial for improving access speed to frequently requested data and reducing the load on original storage locations. The concepts of cache hits and misses are central to understanding caching efficiency.
- **Understanding CDNs**: A CDN is a globally distributed network of cache servers. It serves user requests through edge caches located closer to the user, minimizing latency that might occur when retrieving data from distant origin servers.
- **Static vs Dynamic Caching**: While CDNs are traditionally known for caching static content, the talk highlights challenges associated with dynamic content, which changes frequently. Multiple strategies of caching, including push and pull CDNs, are addressed, showcasing their advantages and drawbacks.
- **Routing and Control**: The importance of routing requests geographically and controlling cached content via HTTP headers is discussed. Key directives, such as cache control and surrogate control headers, play a crucial role in managing how long responses can be cached.
- **Innovative Features**: The talk introduces features like TCP keep-alives and instant purging, which enhance cache performance and enable real-time updates of dynamic content — a significant advantage for dynamic data caching.
- **Rails Plugin**: To facilitate integration of dynamic caching in Rails applications, a Fastly Rails gem is suggested, which simplifies the process of creating unique cache keys and managing purging actions during data updates.
- **Incremental Approach**: Concluding recommendations encourage an iterative approach to implementing edge caching across endpoints, ensuring manageable complexity while maximizing performance gains.

In conclusion, for Rails applications to benefit from edge caching, a fundamental understanding of caching mechanisms and careful implementation of dynamic caching strategies are vital. Leveraging CDNs can significantly enhance user experience by reducing latency and ensuring content is always up-to-date.
