Deconstructing Monolithic Apps with SHIFT Commerce

Editor’s Note: One of the joys of building Heroku is hearing about the exciting applications our customers are crafting. SHIFT Commerce – a platform helping retailers optimize their e-commerce strategy – is a proud and active user of Heroku in building its technology stack. Today, we’re clearing the stage for Ryan Townsend, CTO of SHIFT , as he provides an overview of SHIFT’s journey into building microservices architecture with the support of Apache Kafka on Heroku. Software architecture has been a continual debate since software first came into existence. The latest iteration of this long-running discussion is between…

Scaling ipify to 30 Billion Requests and Beyond on Heroku

The following is the story of how Randall Degges created a simple API to solve the common problem of external IP address lookup and how he scaled it from zero to over 10 thousand requests per second (30B/month!) using Node.js and Go on Heroku. Several years ago I created a free web service, ipify . It is a highly scalable IP address lookup service. When you make a GET request against it, it returns your public-facing IP address. Try it out yourself!

 

I created ipify because, at the time, I was building complex infrastructure management software and needed…

Jekyll on Heroku

Jekyll , the static website generator written in Ruby and popularized by GitHub, is a great candidate for being run on Heroku. Originally built to run on GitHub Pages, running Jekyll on Heroku allows you to take advantage of Jekyll’s powerful plugin system to do more than convert Markdown to HTML. On my blog, I have plugins to download my Goodreads current and recently read books and to generate Open Graph images for posts. That said, it’s not straightforward to get up and running on Heroku without using jekyll serve to do the heavy lifting. jekyll serve uses Ruby’s…

Container Registry & Runtime GA: Deploy Docker Images to Heroku

In the last few years Docker has emerged as a de facto standard for packaging apps for deployment. Today, Heroku Container Registry and Runtime is generally available, allowing you to deploy your Docker images directly to Heroku.

With Container Registry, you get all of the benefits of Docker — a great local development experience and flexibility to create your own stack — with the benefits of running on Heroku: maintained infrastructure, container orchestration, routing, the leading add-ons ecosystem, and a world-class security & operations team.

To deploy your Docker image to Heroku, simply run one command…

Announcing Heroku ChatOps for Slack

Today we’re making our Slack integration generally available to all Heroku customers through the release of Heroku ChatOps.

ChatOps is transforming the way dev teams work, replacing the asynchronous communication and context-switching of traditional operations processes with a shared conversational environment so teams can stay focused, communicate in real-time, gain visibility, and speed joint decision making.

Having seen the benefits of Slack integration for managing our own apps, we wanted to make ChatOps easier to use and accessible to every dev team. Heroku ChatOps handles the complexity of user onboarding, authentication, and accountability between Slack & Heroku,…

Hello RedBeat: A New Celery Beat Scheduler

The Heroku Connect team ran into problems with existing task-scheduling libraries. Because of that, we wrote RedBeat , a Celery scheduler that stores scheduled tasks and runtime metadata in Redis . We’ve also open-sourced it so others can use it. Here is the story of why and how we created RedBeat.

Why We Created the RedBeat Celery Scheduler

Heroku Connect makes heavy use of Celery to synchronize data between Salesforce and Heroku Postgres . Celery is an asynchronous task queue that lets us schedule and queue jobs for execution by a background worker process. Over time, our…

Yarn: Lock It in for Deterministic Dependency Resolution

Choices are an important part of a healthy open source software community. That’s why we’re excited about Yarn, a new package manager that addresses many of the problems with Node’s default package manager, npm . While npm has done a fantastic job creating a large and vibrant JavaScript ecosystem, I want to share why Yarn is an important addition to the Node.js ecosystem, how it will improve your Node.js development experience, and how Heroku has incorporated it into the build process for your Heroku apps.

We began testing Yarn almost immediately after it was released, and…

Announcing the Sydney, Australia Region for Heroku Private Spaces

Today we’re happy to announce that the Sydney, Australia region is now generally available for use with Heroku Private Spaces . Sydney joins Virginia, Oregon, Frankfurt, and Tokyo as regions where Private Spaces can be created by any Heroku Enterprise user. Developers can now deploy Heroku apps closer to customers in the Asia-Pacific area to reduce latency and take advantage of the advanced network & trust controls of Spaces to ensure sensitive data stays protected.

Usage

To create a Private Space in Sydney, select the Spaces tab in Heroku Dashboard in Heroku Enterprise, then click…

Announcing the New Heroku CLI: Performance and Readability Enhancements

Today we are announcing the newest version of the Heroku CLI . We know how much time you spend in the CLI as developers and how much pride you take in being able to get things done quickly. Our new CLI has big improvements in performance as well as enhanced readability for humans and machines.

Tuned for Performance

CLI response time is made up of two parts: the API response time and the performance of the CLI itself, and the latter is where we’ve made big improvements. While a typical Unix user should experience responses…

Data Pipelines with Kafka and Functional Reactive Programming with Node.js

Heroku recently released [a managed Apache Kafka][1] offering. As a Node.js developer, I wanted to demystify Kafka by sharing a simple yet practical use case with the many Node.js developers who are curious how this technology might be useful. At Heroku we use Kafka internally for a number of uses including data pipelines . I thought that would be a good place to start.

When it comes to actual examples, Java and Scala get all the love in the Kafka world. Of course, these are powerful languages, but I wanted to explore Kafka from the perspective of Node.js. While there are…
