Introducing Heroku Flow: Pipelines, Review Apps, and GitHub Sync for Continuous Delivery

Editor’s Note: Heroku Pipelines is now Generally Available. Learn more about Continuous Delivery at Heroku.

At Heroku we’re building a solid platform for delivering apps in a deliberate, reliable manner. We know that reasoning about the state and progress of code changes, testing and verifying what’s deployed, and tracking what works can all be difficult — especially for non-engineering team members.

So we’re proud to introduce Heroku Flow, a new and flexible way to …

Introducing Improved Performance Dynos

Last year, we launched the original Performance dyno, designed to support the largest apps running at-scale with more consistent service and faster response times. Today, with the goal of continuing to support our fast growing customers with more flexibility to choose the type of dynos best for their applications, we are excited to announce improvements to our performance dyno lineup:

  • Performance-L — an improved and more powerful version of the existing Performance dyno, renamed the

Docker support updates: Local data stores and more languages

This helps you use local containers to run, test and deploy Heroku apps that have complex service dependencies with minimal setup and configuration.

We Patched Ruby On Rails for a 10% Performance Bump

In a recent patch we improved Rails response time by >10%, our largest improvement to date. I’m going to show you how I did it, and introduce you to the tools I used, because.. who doesn’t want fast apps?

In addition to a speed increase, we see a 29% decrease in allocated objects. If you haven’t already, you can read or watch more about how temporary allocated objects affect total memory use. Decreasing memory pressure on an app may allow it to be run on a smaller dyno type, or spawn more worker processes to handle more throughput. Let’s back up though, how did I find these optimizations in Rails in the first place?

Preparing Our Response to the OpenSSL Security Flaw

Earlier this month, the OpenSSL project team announced that three days later it would be releasing a new version of OpenSSL to address a high-severity security defect. In the end, this vulnerability resulted in another non-event for our customers, but we thought it might be useful and informative to share the process we went through to prepare for the issue.
