Welcome to Heroku, CloudBees developers

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, and in fact we have many Heroku customers today taking advantage of Jenkins and other CI services. We’re also pleased to see CloudBees suggest that…

Hutils – Explore your structured log data

Many of Heroku's internal components make heavy use of logfmt to log information about what's going on in production. The format is hugely valuable in that it allows us to retroactively analyze what happened during any arbitrary request to our components, query our log traces in very flexible ways, and combined with Splunk, easily generate arbitrary metrics on historical data. It's unquestionably been an invaluable tool for fixing countless bugs, tracking down the root cause of many production incidents, and assessing usage in ways that would have been difficult otherwise. That said, when viewed in the wrong light, logfmt is…

Try the new Uber API on Heroku

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. To deploy the Uber sample on Heroku and experiment with the new Uber API, simply register on the Uber developer site and then click the button below: Once…

Cedar-14 Public Beta

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 Celedon Cedar stack: cedar-14. cedar-14 is built on the latest LTS version of Ubuntu Linux and has recent versions of libraries and system dependencies that will receive…

Retrospectives

Retrospectives are a valuable tool for software engineering teams. Heroku consistently uses retrospectives to review operational incidents, root cause problems, and generate remediation tasks to improve our systems. Increasingly we use retrospectives for another purpose: to improve teamwork and interactions on projects. Here we intentionally avoid technical discussions and focus on the emotional and human aspects of work, with the goal of creating positive insights into how to improve as a team. When The most common times people conduct retrospectives are after some bad incident, or at the conclusion of a big project. These are worthwhile times, but there are…

The New Heroku Postgres Database Experience

Today Heroku is rolling out one of the most significant upgrades ever to our Postgres Database-as-a-Service. This new release is focused on a set of services that run on top of your Heroku Postgres database, making it easier to understand and operate, especially at scale. 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. These features represent a new experience for our Postgres service, which we collectively call DbX, for database experience. The highlight of these new features is Performance…
