Managing apps and users with fine-grained access controls

In February, we announced Heroku Enterprise , with collaboration and management capabilities for building and running your app portfolio in a governable and secure way on Heroku. We also introduced fine-grained access controls with app privileges as a beta feature. Today, we are pleased to announce general availability of this feature: Heroku Enterprise accounts are now automatically enabled for fine-grained access controls. We’re very happy to deliver this feature that many of our largest customers have requested.

“Enterprises need greater visibility around applications and scalability, and Heroku Enterprise adds those features to the core Heroku value proposition,” said Matthew Francis,…

Improved production stability with circuit breakers

Fun fact: the Heroku API consumes more endpoints than it serves. Our availability is heavily dependent on the availability of the services we interact with, which is the textbook definition of when to apply the circuit breaker pattern .

Heroku Redis GA and Introducing Heroku Data Links

Today we’re pleased to announce general availability of Heroku Redis with a number of new features and a more robust developer experience. By giving developers a different data management primitive, we’re helping them meet the needs of building modern, scalable applications. The classic example of using multiple data stores in an application is the e-commerce site that stores its valuable financial information in a relational database while the user session tokens are saved in a key-value store like Redis. This is one of the use cases where Redis has proven to be instrumental in solving problems like…

Introducing Heroku CX Patterns: Building Customer Experiences on Heroku with Salesforce Services

A quick glance at most any phone shows the importance and urgency – for businesses of all kinds – of creating mobile customer apps. Our everyday activities – finding a ride , ordering a meal or turning on a light are increasingly mobile experiences.

But delivering a great omnichannel experience to customers requires more than just the work of the application developer. The larger organization is involved in following up with prospects, fielding service inquiries, and sending relevant marketing messages. Orchestrating this tapestry of touchpoints often requires developers to integrate with systems used by non-developers, including sales,…

How to Secure the Celery Task Queue with Fernet

Celery is by far the most popular library in Python for distributing
asynchronous work using a task queue. If you’re building a Python web app,
chances are you already use it to send email, perform API integrations, etc.
Many people choose Redis as their message broker of choice because
it’s dead simple to set up: provision a Redis add-on, use its environment
variable as your BROKER_URL, and you’re done. But the simplicity of Redis
comes at a cost. Redis does not currently support SSL , and
it doesn’t seem like that’s going to change any time soon .
Because Heroku add-ons communicate over the public web, that…

New Heroku Dashboard and Metrics now in Beta

At Heroku, we’re focused on delivering thoughtfully designed systems to improve developer productivity and experience. We firmly believe that improving the development and operations experience helps developers to build and run better apps. This improvement allows developers to focus more on functionality, and businesses to focus more on the value of their applications.

Today we are pleased to announce two new features, both in public beta, that support this mission: a new Heroku Dashboard and Heroku Metrics. These new systems bring developers powerful new clarity and simplicity around application management, execution, and optimization.

New Heroku Dashboard:…

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 define their applications' details, setup configurations and runtime environments in a structured way. Instead of providing step-by-step instructions, you can now add app.json…

Introducing the Heroku HTTP API Toolkit

Today we’re open sourcing the toolchain Heroku uses to design, document, and consume our APIs. We hope this shows how Heroku thinks about APIs and gives you new tools to create your own APIs.

This toolkit includes our HTTP API design guide, the prmd tool for managing JSON schemas and generating API docs, and client generators for Ruby and Go.

Here’s some more information about these things, how we use them at Heroku, and an explanation of how you can try them yourself.

Auto-generating a Go API client for Heroku

Editor's note: This is a cross post from Blake Gentry, an engineer at Heroku.

This is a post about the recently announced Heroku Platform API JSON Schema and how I used that schema to write an auto-generated Go client for the API.

Heroku's API team has spent a large part of the past year designing a new version of the platform API . While this is the 3rd incarnation of the API, neither of the two previous versions were publicly documented. In fact, the only documentation on the old APIs that was ever published is…

Adding Concurrency to Rails Apps with Unicorn

With support for Node.js, Java, Scala and other multi-threaded languages, Heroku allows you to take full advantage of concurrent request processing and get more performance out of each dyno. Ruby should be no exception.

If you are running Ruby on Rails with Thin, or another single-threaded server, you may be seeing bottlenecks in your application. These servers only process one request at a time and can cause unnecessary queuing. Instead, you can improve performance by choosing a concurrent server such as Unicorn which will make your app faster and make better use of your system resources. In this…
