Shopify has taken Rails through some of the world's largest sales: Superbowl, Celebrity Launches, and Black Friday. In this talk, we will go through the evolution of the Shopify infrastructure: from re-architecting and caching in 2012, sharding in 2013, and reducing the blast radius of every point of failure in 2014. To 2016, where we accomplished running our 325,000+ stores out of multiple datacenters. It'll be whirlwind tour of the lessons learned scaling one of the world's largest Rails deployments for half a decade.

There is a value in writing tests and there is also a cost. The currency is time. The trade-offs are difficult to evaluate because the cost and value are often seen by different people. The writer of the test bears much of the short term cost while long term benefits and cost are borne by the rest of the team. By planning around both the the cost and value of your tests, you’ll improve your tests and your code. How much do slow tests cost? When is it worth it to test an edge case? How can you tell if testing is helping? Here are some strategies to improve your tests and code.

Perhaps you've thought about switching to Webpack. Then you open a Webpack config file and your heart sinks; it looks like an alien life-form. You try to get it working, but your old jQuery plugins won't even load in the browser.

Moving from Webpack basics to using it in production means understanding how it works. We'll demystify how Webpack bundles assets for the browser, how it differs from the Rails asset pipeline, and highlight common challenges that may occur coming from Sprockets.

This is the talk we would have wanted to see before recently adopting Webpack in our own Rails app.

As developers we spend hours optimizing our code, often overlooking a simpler, more efficient way to make quick gains in performance: application server configuration.

Come learn about configuration failures that could be slowing down your Rails app. We’ll use tooling on Heroku to identify configuration that causes slower response times, increased timeouts, high server bills and unnecessary restarts.

You’ll be surprised by how much value you can deliver to your users by changing a few simple configuration settings.
