Why Microservices, Decomposing Big Projects, Matter

All successful applications grow more complex over time, and that complexity creates challenges in development. There are two essential strategies to manage this problem: a team can keep everything together (create a monolith) or a team can divide a project into smaller pieces (create microservices).

The monolith at its most extreme is a single code base that contains all of an application’s logic and to which all programmers involved contribute. This approach is perhaps the …

Introducing the app.json Application Manifest

Developers want to spend less time setting up applications and start working with the code sooner. Setting up applications is error-prone, time consuming and interruptive to the development flow. Often, there are several steps to go from your code or other samples and templates that you find in repositories online, to a running application that you can continue to work on.

Today, we are excited to introduce the app.json manifest. app.json enables developers to …

Run JRuby on Heroku: Ruby with JVM-Based Libraries

Over a year ago Heroku launched the Cedar stack and the ability to run Java on our platform. Java is known as a powerful language – capable of performing at large scale. Much of this potential comes from the JVM that Java runs on. The JVM is the stable, optimized, cross-platform virtual machine that also powers other languages including Scala and Clojure. Starting today you can leverage the power of the JVM in your …

Presenting the New Add-ons Site

Heroku Add-ons make it easy for developers to extend their applications with new features and functionality. The Add-on Provider Program has enabled cloud service providers with key business tools, including billing, single sign-on, and an integrated end-user support experience. Since the launch of the Heroku Add-ons site over two years ago, the marketplace has grown to nearly 100 add-ons. As the add-ons ecosystem has grown, we've learned a lot about how cloud service providers structure …

Buildpacks: Heroku for Everything

Last summer, Heroku became a polyglot platform, with official support for Ruby, Node.js, Clojure, Java, Python, and Scala. Building a platform that works equally well for such a wide variety of programming languages was a unique technical design challenge.

siloed products would be a non-scalable design

We knew from the outset that maintaining siloed, language-specific products – a Heroku for Ruby, a Heroku for Node.js, a …

New Status Page with Real-Time Incident Updates

Developers like you deploy code to hundreds of thousands of apps every month on the Heroku platform. Some of these are production apps which serve hundreds of millions or even billions of requests per month. Uptime of the platform is critical for such apps.

We want to achieve the sustained reliability that these apps require. But when there are incidents that impact uptime, we want to maximize our transparency and accountability to you and all …

RabbitMQ Add-on Now Available on Heroku

Today we're proud to announce the availability in beta of RabbitMQ add-on by VMWare. RabbitMQ is an open source implementation of the AMQP protocol that provides a robust, scalable and easy-to-use messaging system built for the needs of cloud application developers.

Getting Started

With the add-on, provisioning a fully managed RabbitMQ instance couldn't be easier to do:

$ cd rabbitdemo $ heroku addons:add rabbitmq -----> Adding rabbitmq to rabbitdemo... done, v2 (free) $ heroku config…

Defaulting to Ruby 1.9.2

Heroku is fully behind Ruby 1.9.2 as the new gold standard for production Ruby apps. Over the past few months, we’ve seen more and more developers move to the Bamboo 1.9.2 stack. It’s fast, stable, and increasingly sees excellent support throughout the community.

In February, we said that we’d be reviewing the state of 1.9.2 support with the eventual goal of switching the default for new Ruby apps on Heroku from 1.8.7 to 1.9.2. …

Heroku Casts: Setting Up Custom Domains

NOTE: This documentation is out-of-date and no longer supported. It will not work with the current version of the Heroku platform. For the latest information about setting up custom domains on Heroku please use this article from the Heroku Dev Center.

Today is a twofer on the screencast front.

Setting up custom domains & DNS is one of those necessary evils that no one likes, and is way more confusing than it should be. Adding …
