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 to dynamically discover the public IP address of some cloud instances without using any management APIs.

When I searched online for freely

The 2017 Heroku Retrospective: Advancing Developer Experience, Data, and Trust

2017 was a great year for Heroku and our users. We want to thank each of you for your feedback, beta participation, and spirit of innovation, which inspires how we think about our products and evolve the platform.

In the past year, we released a range of new features to make the developer experience even more elegant. We bolstered our existing lineup of data services while providing security controls for building high compliance applications on the platform.

With that, we’d like to take a moment and share some of the highlights from 2017. We hope you enjoy it, and we look forward to an even more exciting 2018!

Announcing the New Heroku Partner Portal for Add-ons

We are excited to announce that the new Heroku Partner Portal for Add-ons is now generally available.

The new portal offers an improved partner experience for building, managing, and updating Heroku add-ons. Our goal is to create a workflow that will give you more freedom and enable you to bring your add-ons to market more easily.

The new portal has been organized into a simple, elegant interface that is similar to the rest of Heroku's products. In each section, we've made more functionality available via the portal interface, where in the past emails or support tickets might have been necessary. This release brings a more visual approach as well as greater focus to creating and managing key aspects of your add-on offerings such as Marketplace Listing, Feature Plans, and Reports.

Meltdown and Spectre Security Update

Yesterday, researchers disclosed a security vulnerability affecting side-channel analysis of speculative execution on modern computer processors (CVE-2017-5715, CVE-2017-5753, and CVE-2017-5754).

Heroku’s Product Security team follows emerging trends, and partners closely with the research community. We invest heavily in facilitating conversations regarding vulnerabilities and keeping our customers safe via community partnerships.

In the case of emerging and recently-announced vulnerabilities (including those embargoed or leaked to the press), we have a proven methodology for ingesting, processing, and prioritizing mitigation work. Our team utilizes these methods to address these vulnerabilities as material or actionable information is made available.

Our Security and Platform teams are working closely with AWS and Canonical (makers of the Ubuntu Linux operating system) to investigate and patch any affected systems related to the Meltdown and Spectre announcements. If customer impact or coordination is required, we will post additional information via Heroku Status, DevCenter ChangeLog, or provide instructions

Kafka Streams on Heroku

Designing scalable, fault tolerant, and maintainable stream processing systems is not trivial. The Kafka Streams Java library paired with an Apache Kafka cluster simplifies the amount and complexity of the code you have to write for your stream processing system.

Unlike other stream processing systems, Kafka Streams frees you from having to worry about building and maintaining separate infrastructural dependencies alongside your Kafka clusters. However, you still need to worry about provisioning, orchestrating, and monitoring infrastructure for your Kafka Streams applications.

Heroku makes it easy for you to deploy, run, and scale your Kafka Streams applications by using supported buildpacks from a variety of Java implementations and by offering a fully-managed Kafka solution for handling event streams. That way, you can leverage the Heroku Runtime alongside Apache Kafka on Heroku to manage your Kafka Streams applications so you can focus on building them. Kafka Streams is supported on Heroku with

PostgreSQL 10 Generally Available on Heroku

Today, we're happy to announce full support for PostgreSQL 10, opening our managed Postgres solution to the full slate of features released after a successful two-month Beta period. PostgreSQL 10 is now the default version for all new provisioned Heroku Postgres databases. All Postgres extensions, tooling, and integration with the Heroku developer experience are ready to use, giving you the power of PostgreSQL 10 with the ease and usability of Heroku for building data-centric applications.

We'd like to re-emphasize a few features – among the many released in Postgres 10 – that we are particularly excited about.

Native Table Partitioning

A pattern we often see in databases in our fleet is one or two tables growing at a rate that’s much larger and faster than the rest of the tables in the database. Query times within the application will start to rise, bulk loads will take longer, and creating indexes

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 built-in, single threaded web server WEBrick, but a public site should be using a web server more suited for production, like nginx.

We’ll start from the very beginning. You’ll need Ruby and Bundler installed.

I like ruby-install and chruby as my Ruby installer and switcher.

This is the platform-agnostic way

Announcing PCI Compliance for Heroku Shield

In June we announced Heroku Shield with new high compliance features for Heroku Private Spaces. Heroku Shield enables businesses like AlignTech to deploy apps that handle protected healthcare information (PHI) in accordance with government regulations.

Today, we are proud to announce that Heroku Shield Services have been validated as PCI Level 1 Service Provider compliant. This designation helps our customers understand how Heroku's systems and human processes work together to safeguard customer data. It helps security and audit teams in choosing Heroku as a platform for running a company's most critical apps.

Further Strengthening Trust with PCI

The Payment Card Industry Data Security Standard (PCI DSS) is one of the most widely known, industry-defined security standards. It mandates explicit security controls and requires certified organizations to be audited by a qualified security assessor. The combination of rigor and broad adoption makes PCI a valuable tool for building trust between Heroku

Announcing Heroku Private Space Peering for AWS

Two years ago, we introduced Heroku Private Spaces as a new platform abstraction that combines powerful network isolation features with the seamless developer experience of Heroku.

Today we are announcing Heroku Private Space Peering, a new capability to connect the isolated Private Space network to apps and services in AWS VPCs controlled by you. Now you can build apps in Heroku that connect securely and privately to backend systems and workloads in AWS like a directory service, a search stack, a data warehouse, or a legacy SQL database.

How It Works

Private Space Peering is available to all Heroku Enterprise customers. Setting up a peering connection takes just a few simple actions. After you have initiated the peering connection on your AWS VPC, it will show up in the list of peerings for your Private Space in the Dashboard Network tab:

Heroku Connect Update: Fast Writes, Global Deployment, and a Guided Management Experience

Today we are pleased to announce a significant update to Heroku Connect, one that is a culmination of two years of work to improve every aspect of the service. We’ve focused on three primary areas: improving write speed, geographically expanding the service, and intelligently guiding design and troubleshooting workflows. To that end, we’ve enabled bulk writes resulting in a 5x average increase in sync performance to Salesforce, deployed Connect in six global regions to be closer to customers’ databases, and built three guided management experiences that significantly increase user productivity.

Collectively, these enhancements will enable Heroku Connect to continue to meet the ever increasing demands of enterprise customers.

Enterprise Scale Data Integration

We’ve been fortunate to see rapid adoption of Connect amongst our largest enterprise customers. Not surprisingly, these customers tend to have large amounts of data, complex data models, and very high expectations when it comes to performance.

PostgreSQL 10 Now Available in Beta on Heroku Postgres

Earlier this month, PostgreSQL 10.0 was released. Today, we are excited to announce PostgreSQL 10 is available in beta on Heroku, bringing a number of notable feature and performance improvements to our managed PostgreSQL database service.

The beta provides customers who want to try out the new release an easy way to do so, while customers who are happy with the current version can continue to stay on version 9.6 until we make version 10 generally available. Also, new databases will continue to default to version 9.6 until we release version 10 to GA.

While PostgreSQL 10 has many feature and performance benefits, we’d like to highlight several that we are most looking forward to:

Performance Improvements

Most Heroku Postgres users will notice a performance boost when using PostgreSQL 10 for certain types of queries. The introduction of improved parallel queries, which optimize common types

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 in the directory of your Dockerfile:

$ heroku container:push web

In the Cloud, No One Can Hear Your OutOfMemoryError

Pushing an app to the cloud can feel like launching a probe into space. Once your project is thousands of miles away you can't bang on it with a hammer or replace broken parts when there's a problem. Your debugging efforts must rely on the instrumentation, telemetry, and remote controls included with the app when it was deployed. On Heroku, we've gladly done some of that prep work for you.

Two new Heroku features, Heroku Exec and Language Runtime Metrics, improve your production monitoring, inspecting, and debugging experience on the platform. With Heroku Exec, you can create secure TCP and SSH tunnels into a dyno, which facilitate SSH sessions, port forwarding, remote debugging, and most popular diagnostic tools. Our Language Runtime Metrics feature supplements these tools by displaying detailed time series metrics in your Heroku dashboard.

You can try Heroku Exec right now by running the following command on any

Eclipse Mat

Heroku Exec and Language Runtime Metrics GA: Runtime Debugging on Heroku

We’ve all been there — you push your code to production and a leak causes memory usage to grow out of control. To determine the root cause of the problem, you need to be able to monitor, inspect, and debug the production application, collecting detailed data at runtime.

Today we’re making it even easier to debug your applications on Heroku, with the general availability of Language Runtime Metrics, starting with JVM languages, and Heroku Exec. Language metrics surfaces key indicators of an issue, like garbage collection activity, and heap and non-heap memory usage, on a unified timeline in the Heroku Dashboard.

After you’ve identified an issue, you can use Exec to connect to a dyno at runtime, via SSH, for further inspection and remote debugging. When combined with Application Metrics, Language Runtime Metrics and Exec provide a robust set of tools for maintaining production application health.

Runtime Inspection with

Kafka Everywhere: New Plans and Pricing for Apache Kafka on Heroku

Event-driven architectures are on the rise, in response to fast-moving data and constellations of inter-connected systems. In order to support this trend, last year we released Apache Kafka on Heroku – a gracefully integrated, fully managed, and carefully optimized element of Heroku's platform that is the culmination of years of experience of running many hundreds of Kafka clusters in production and contributing code to the Kafka ecosystem.

Today, we are excited to announce additional plans and pricing in our Kafka offering in order to make Apache Kafka more accessible, and to better support development, testing, and low volume production needs.

Apache Kafka on Heroku: Now With More Flexibility and Speed

Apache Kafka is a powerful, distributed streaming platform, and the dominant open source solution in managing high scale event streams. Kafka enables you to easily design and implement architectures for many important use cases, such as elastic queuing, data pipelines

Heroku Webhooks: Powering New Integrations and Real-time Notifications

We're happy to announce that Heroku app webhooks is now generally available for all Heroku customers.

App webhooks provide notifications when your Heroku app changes, including modifications to domain settings, releases, add-ons, and dyno formations. These notifications can empower your internal communications, dashboards, bots or anything else that can receive HTTP POST requests. Integrating with Heroku webhooks provides easy support for driving custom workflows and 3rd party tools.

Creating webhooks

With the webhooks CLI plugin, you can subscribe to events with a single command.

heroku plugins:install heroku-webhooks        
heroku webhooks:add -i api:release -l notify -u -a your-app  

In this example, after a new release is created for your-app, Heroku sends a POST request to your server endpoint with the details of the event. The example below shows the first section of a typical POST request:


Receiving webhooks

Webhooks are delivered by POST requests to a designated, publicly accessible URL.

Evolution of the Heroku CLI: 2008-2017

Over the past decade, millions of developers have interacted with the Heroku CLI. In those 10 years, the CLI has gone through many changes. We've changed languages several times; redesigned the plugin architecture; and improved test coverage and the test framework. What follows is the story of our team's journey to build and maintain the Heroku CLI from the early days of Heroku to today.

  1. Ruby (CLI v1-v3)
  2. Go/Node (CLI v4)
  3. Go/Node (CLI v5)
  4. Pure Node (CLI v6)
  5. What's Next?

Ruby (CLI v1-v3)

Our original CLI (v1-v3) was written in Ruby and served us well for many years. Ruby is a great, expressive language for building CLIs, however, we started experiencing enough problems that we knew it was time to start thinking about some major changes for the next version.

For example, the v3 CLI performed at about half the speed on Windows as it did on Unix. It was
