Rails 5 will be the easiest release ever to get running on Heroku. You can get it going in just five lines:

$ rails new myapp -d postgresql $ cd myapp $ git init . ; git add . ; git commit -m first $ heroku create $ git push heroku master 

These five lines (and a view or two) are all you need to get a Rails 5 app working on Heroku — there are no special gems you need to install, or flags you must toggle. Let's take a peek under the hood, and explore the interfaces baked right into Rails 5 that make it easy to deploy your app on any modern container-based platform.

Production Web Server as the Default

Before Rails 5, the default web server that you get when you run $ rails server is...

We recently sat down for a chat with Bill Curtis, a co-founder and the CTO of Sweet Tooth, a points and rewards app for online stores worldwide.

What has been your greatest challenge?

We’re serving way more data today than we ever have, so scaling is mission-critical. In the past, we’ve struggled with traffic spikes. For example, there are seasonal spikes, like Black Friday or Cyber Monday. There are also spikes from merchant activity, such as load testing stores or importing a large number of orders.

I recently tweeted our requests-per-hour graph. It showed that during the huge spikes for this year’s Black Friday and Cyber Monday, our product availability was seamless on Heroku. That...

Based in Tel Aviv, Israel, Vitali Margolin is the Head of R&D for Roomer. Vitali leads a team of seven developers who built and operate the travel marketplace www.roomertravel.com and the travel protection service www.life-happens.com, both running on Heroku.

What are you running on Heroku?

The four big projects are: the Roomer website, our administration app, our partner network and B2B website, and the Roomer API. The Roomer API is our highest load app. It can get up to 10k requests per minute from partner integrations such as Kayak. We have a few more technical products, including an app that does text recognition and automatically decodes confirmation emails, as well as a smart...

In 2013, Rafael Ördög put poker and code together, the result: Lean Poker, a competitive coding event that teaches continuous deployment and lean startup methodologies. Rafael is based in Budapest, Hungary.

What's Lean Poker?

Lean Poker is a coding workshop that is designed to teach people how to practice continuous deployment and lean startup methodologies. Companies can sponsor a free public event or hold an internal, team-building event for their own employees.

The basic starting code is really simple and teams can use the language of their choice. The challenge is not to understand an existing code base but to modify it—to build a new app. Teams must iterate their app quickly in...

Rails 5 has been brewing for more than a year. To take advantage of new features, and stay on the supported path, you'll need to upgrade. In this post, we'll look at the upgrade process for a production Rails app, codetriage.com. The codebase is open source so you can follow along. Special thanks to Prathamesh for his help with this blog post.

How Stable is the Beta?

In Rails a beta means the API is not yet stable, and features will come and go. A Release Candidate (RC) means no new features; the API is considered stable, and RCs will continue to be released until all reported regressions are resolved.

Should you run your production app on the beta? There is value in getting a...
