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 …

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 …

Heroku Redis Now Available in Public Beta

Developers increasingly need a variety of datastores for their projects — no one database can serve all the needs of a modern, scalable application. For example, an e-commerce app might store its valuable transaction data in a relational database while user session information is stored in a key-value store because it changes often and needs to be accessed quickly. This is a common pattern across many app types, and the need for a key-value store …

New Dyno Types and Pricing Public Beta

We’ve always provided a developer experience so you can create amazing apps, from hacking on new technologies and personal projects to building production applications and the most demanding high traffic apps. As Heroku has evolved, you’ve asked us for more choices when it comes …

Schedule PostgreSQL Backups with PG Backups Add-on

Performing a backup is one of those tasks that ensures your application can recover from database or hardware failures should they ever occur. Over four year ago, we recognized this as a best practice and came out with PGBackups, an add-on that reduces the risk and complexity of taking database backups. Today, we’re pleased to announce two big improvements: enhanced reliability, and the ability to schedule backups.

Better By Default

Incremental Garbage Collection in Ruby 2.2

This article introduces incremental garbage collection (GC) which has been introduced in Ruby 2.2. We call this algorithm RincGC. RincGC achieves short GC pause times compared to Ruby 2.1.

Debugging Super Methods with Ruby 2.2

Debugging a large codebase is hard. Ruby makes debugging easier by exposing method metadata and caller stack inside Ruby's own process. Recently in Ruby 2.2.0 this meta inspection got another useful feature by exposing super method metadata. In this post we will look at how this information can be used to debug and why it needed to be added.

Short Time Outs and Asynchronous Requests on Heroku

Working with our support team, I often see customers having timeout problems. Typically, their applications will start throwing H12 errors.

The decision to timeout requests quickly wasn’t made to avoid having long-running requests on our router, nor to only have fast apps on our platform, but because standard web servers do not handle these types of requests particularly well.
