Heroku is a cloud Platform-as-a-Service (PaaS) supporting several programming languages that is used as a web application deployment model. Heroku, one of the first cloud platforms, has been in development since June 2007, when it supported only the Ruby programming language, but now supports Java, Node.js, Scala, Clojure, Python, PHP, and Go. For this reason, Heroku is said to be a polyglot platform as it lets the developer build, run and scale applications in a similar manner across all the languages. Heroku was acquired by Salesforce.com in 2010.

  • Using Heroku's Expensive Query Dashboard to Speed up your App
    I recently demonstrated how you can use Rack Mini Profiler to find and fix slow queries. It’s a valuable tool for well-trafficked pages, but sometimes the slowdown is happening on a page you don't visit often, or in a worker task that isn't visible via Rack Mini Profiler. How can you find and fix those slow queries? Heroku has a feature called expensive queries that can help you out. It shows hi...

  • On the Rise of Kotlin

  • Announcing Release Phase: Automatically Run Tasks Before a New Release is Deployed
    You’re using a continuous delivery pipeline because it takes the manual steps out of code deployment. But when a release includes updates to a database schema, the deployment requires manual intervention and team coordination. Typically, someone on the team will log into the database and run the migration, then quickly deploy the new code to production. It's a process rife with deployment risk....

  • On Building Tools for Developers: Heroku CI
    How we built Heroku CI: our product intuition checked against what the market wants (we surveyed ~1000 developers to figure out the latter, and the results were surprising) Two approaches to building any product are often in tension: designing from inspiration, and designing from information. On the pure inspiration side, you just build the product you dream of, and trust that it will be so aweso...

  • Sockets in a Bind
    Back on August 11, 2016, Heroku experienced increased routing latency in the EU region of the common runtime. While the official follow-up report describes what happened and what we've done to avoid this in the future, we found the root cause to be puzzling enough to require a deep dive into Linux networking. The following is a write-up by SRE member Lex Neva (what's SRE?) and routing engineer Fr...
