This blog post is adapted from a talk given by Stella Cotton at RailsConf 2018 titled "So You’ve Got Yourself a Kafka."

In recent years, designing software as a collection of services, rather than a single, monolithic codebase, has become a popular way to build applications. In this post, we'll learn the basics of Kafka and how its event-driven process can be used to power your Rails services. We’ll also talk about practical considerations and operational challenges that your event-driven Rails services might face around monitoring and scaling.

What is Kafka?

2018 was an amazing year for Heroku and our customers. We want to extend a big thank you for your feedback, beta participation, and spirit of innovation, which inspires us every day to continuously improve and advance the platform.

In the past year, we released a range of new features to make the developer experience more productive, more standards based, and more open. We achieved significant compliance milestones, provided trust controls for creating multi-cloud apps, and improved our existing lineup of data services.

With that, we’d like to take a moment and look back at some of the highlights from 2018. We hope you enjoy it, and we look forward to an even more exciting 2019!

ruby-2

The Ruby committers have again continued their annual holiday tradition of gifting us a new Ruby version: Ruby 2.6 was released today, including the long awaited Just-In-Time (JIT) compiler that the Ruby team has been working on for more than a year.

Just-In-Time compilation requires Ruby to spin up a compiler process on startup, and we're proud to say that this feature is supported today on Heroku thanks to the diligent efforts of our very own Richard Schneeman. We'd also like to thank fellow Herokai Nobuyoshi Nakada for his effort making sure the new JIT works well with all of the officially supported compilers: GCC, Clang and Microsoft Visual C++.

Building a SaaS product, a system to handle sensor data from an internet-connected thermostat or car, or an e-commerce store often requires handling a large stream of product usage data, or events. Managing event streams lets you view, in near real-time, how users are interacting with your SaaS app or the products on your e-commerce store; this is interesting because it lets you spot anomalies and get immediate data-driven feedback on new features. While this type of stream visualization is useful to a point, pushing events into a data warehouse lets you ask deeper questions using SQL.

In this post, we’ll show you how to build a system using Apache Kafka on Heroku to manage and visualize...


We are happy to announce two major improvements to our SSO experience for Heroku Enterprise customers: easier SSO login for users via the Heroku CLI, and the ability for admins to add more than one certificate at the Enterprise Team level.

Logging into all your different cloud applications can be a pain. We know that many of you like to use Heroku via the command line interface and in your web browser side-by-side, and until now that has meant logging in via SSO separately to each interface. You'll now be redirected from the CLI to the Dashboard to complete your SSO login to Heroku, after which your SSO credentials will be synced.

We've also made the administrative experience for...
