Announcing HTTP Git Beta Support Upgrade

Of the many Platform-as-a-Service innovations Heroku has contributed in its seven year existence, perhaps the most iconic is git push heroku master. Today we’re announcing a significant upgrade to Heroku’s Git implementation: Beta support for Git’s HTTP transport.

HTTP Git has some notable advantages over traditional SSH Git. Instead of relying on port 22 (often blocked by firewalls) HTTP Git runs on port 443, the same port used for secure web requests.

Also, HTTP Git …

Cedar-14 now Generally Available

We’re excited to announce that the Cedar-14 – the new version of the Celedon Cedar stack – is ready for general availability and is now the default stack on Heroku. Cedar-14 is based on the latest Ubuntu LTS Linux version and comes with a modern set of libraries and system dependencies that will stay current and updated for a long time to come.

Since we announced the public beta of Cedar-14 three months ago, we …

Benchmarking Rack Middleware and Improved Speed

Performance is important, and if we can’t measure something, we can’t make it fast. Recently, I’ve had my eye on the ActionDispatch::Static middleware in Rails. This middleware gets put at the front of your stack when you set config.serve_static_assets = true in your Rails app. This middleware has to compare every request that comes in to see if it should render a file from the disk or return the request further up the stack. This post is how I was able to benchmark the middleware and give it a crazy speed boost.

Django and Node together on Heroku

[Heroku Connect] [heroku_connect] is written primarily in Python using Django. It’s an add-on and a platform app, meaning it’s built on the Heroku platform. Part of our interface provides users with a realtime dashboard, so we decided to take advantage of socket.io and node.js for websocket communication. But like all Heroku apps, only one type of dyno can serve traffic. This left us with two choices: manage 2 apps, each with its own repo, and carefully consider when and how we deployed them, or find a way to serve both node and Django traffic from the same app.

Instrumentation by Composition

Heroku provides many instrumentations for your app out of the box through our new Heroku developer experience.

We have open-sourced some of the tools used to instrument Heroku apps, but today’s focus will be on instruments, a Go library that allows you to collect metrics over discrete time intervals.
