A Dialog with Your Data Using the New Dataclips

The data we store holds value, but refining data into meaning remains a difficult task. Over the last few months, we’ve taken a step back to figure out what we can do to help our users cross that divide, and rebuilt Heroku Dataclips from scratch with that goal in mind. The result is an experience that makes accessing and working with your data easier than ever, enabling anyone on your team familiar with SQL to …

Optimizing Database Performance in Rails

Setting up a database is a relatively straightforward process (Heroku has an add-on for that), but getting it to run well in production is sometimes another matter. As your application grows and your data grows along with it, you will likely find a number of performance bottlenecks specifically related to your database, and this post aims to help you diagnose and address those issues when they arise.

As with all components of your infrastructure …

Saved by the Schema: Using JSON Schema to Document, Test, and Debug APIs

Heroku has many public API endpoints. Each of these endpoints needs to be tested so that we know how they work, and documented so that our customers (and other API consumers) know how they work. Follow along, and we’ll learn how Heroku uses JSON Schema to test and document our Platform API – and how it helped us uncover an unexpected bug, rooted in the way the Oj gem parses Big Decimals.

Turn Your Code into Docker Images with Cloud Native Buildpacks

When we open-sourced buildpacks nearly seven years ago, we knew they would simplify the application deployment process. After a developer runs git push heroku master, a buildpack ensures the application’s dependencies and compilation steps are taken care of as part of the deploy.

As previously announced, we’ve taken the same philosophies that made buildpacks so successful and applied them towards creating Cloud Native Buildpacks (CNB), a standard for turning source code into Docker images without the need for Dockerfiles. In this post, we’ll take a look at how CNBs work, how they aim to solve many of the problems that exist with Dockerfile, and how you can use them with the recent beta release of the buildpacks.io project. As part of this release, we’ve created a Heroku buildpacks builder image for Ruby, Node.js, Java, Python, PHP, and Go that works with the CNB tooling.

Bug Bounties and Black Swans: How Heroku Expects the Unexpectable

There’s obviously more to security than humans, technology, and vendors with all of their implementations and expertise. At Heroku we believe that security is a byproduct of excellence in engineering.

All too often, software is written solely with the happy path in mind, and security assurances of that software has its own dangerous assumptions. A mature security program should challenge assumptions of security controls, move to testing continuously, and prepare for the unexpectable.

This means …

PostgreSQL 11 Generally Available on Heroku

After a successful two-month Beta period, PostgreSQL 11 is now the default version for all new provisioned Heroku Postgres databases. All Postgres extensions, tooling, and integration with the Heroku developer experience are ready to use, giving you the power of PostgreSQL 11 with the ease and usability of Heroku for building data-centric applications.

We’d like to re-emphasize a few features – among the many released in Postgres 11 – that we are particularly excited about.
