As an SRE (Service Reliability Engineer) at Heroku, one of the things I’m exposed to is how much work happens behind the scenes in order to create what we call “non-events” for you, our users. A non-event is turning something that would typically create work for an application hosted on traditional infrastructure into something that the user won’t even notice. This is something we put a lot of energy into because we believe in letting …

As part of Salesforce’s Dreamforce conference, Salesforce is hosting its second major hackathon on October 10-12 in San Francisco. The format for this year’s hackathon has been expanded to include specific categories for not just Heroku, but also some of our favorite open source projects. With over ten prizes of more than $10,000 each, this is a great opportunity to build something cool, take advantage of some of the latest Heroku features, and …

Collectively, we call these new features Heroku DX—the next evolution …

The key to any startup is focus — focusing in multiple directions is really no focus at all. Following this premise we understand the decision by CloudBees to double down on their continuous integration offering of Jenkins, and to discontinue their platform as a service product. Continuous integration is already playing an important role in application development and deployment and will only continue to grow in the future. Many of us are fans of Jenkins, …

On Wednesday, Uber launched an API to let developers build new products and services that leverage the Uber ridesharing platform. Uber built a simple Python/Flask app that developers can use when exploring how the API works.

This is the sort of experimentation and innovation that we at Heroku want to enable, so we sent a pull request to add an app.json file to the repo and a Heroku Button to the readme.

At Heroku, we want to give our users access to the latest and greatest software stacks to base their apps on. That’s why we continuously update buildpacks to support new language and framework versions and let users experiment further using third-party buildpacks.

Sitting underneath slugs and buildpacks are stacks. Stacks are the operating system and system libraries required to make apps run. Today we’re releasing into public beta a new version of the …

Today Heroku is rolling out one of the most significant upgrades ever to our Postgres Database-as-a-Service.

In addition, we are rolling out new production database plans with double the memory and 2-3 times the performance of our existing plans at the same cost to you.
