GPU support in IronWorker

In the past few months, we’ve spoken to quite a few customer that have added Machine Learning (ML) tasks into IronWorker. The problem is, these tasks can take a significant amount of time on a CPU vs a GPU. GPU’s were built to handle the parallelization of complex matrix/vector operations that gaming required, and it so happens that deep learning exercises also have similar requirements.

That said, we thought it was about time to add GPU support to IronWorker. We started with a simple test of doing image recognition via TensorFlow. After hacking the example python script to add the ability to download an image via a URL, we zipped up the script and uploaded it to IronWorker. We went ahead and used the latest Tensorflow docker image.

> zip
> iron worker upload --zip --name classify_image tensorflow/tensorflow:latest-gpu python --image_url ""

In this initial push, we released support for the g2, g3 and p2 GPU instances on AWS. Once we fired off that task, here’s what things look like on our end:

It took about 10 seconds of run time for the image classification via IronWorker using a p2.xlarge instance on AWS. We didn’t have a chance to run this against a non-GPU instance, but we’ll leave that as an exercise for the reader. We’re pretty sure it will take a little longer than 10 seconds! The actual output from the script is as follows:

We’ll be working closely with a few customers in the coming months on some large ML/AI projects, and we’ll post as much as we can on their use cases and resulting benchmarks. As ML becomes more and more prominent in Business Intelligence operations, we’re expecting to see a big increase in GPU usage. If you have any questions about our GPU support, drop us a line and we’d be happy to chat.

Robotics with Iron

We recently sponsored a robotics event in Tokyo held by OnLab, DigitalGarage and Psygig… and, it was awesome.  Also, yes… the course below was an actual course from the event.

The participants were to break into teams, build a drone, implement machine learning techniques, gather and analyze data via Iron, and maneuver their drone across multiple courses.  The teams that finished the courses and displayed the most innovative technical solutions were crowned champion.

The ability to utilize GPU instances and fire up containers that run libraries like Keras and TensorFlow allows for the offloading of heavy computational workloads even in highly dynamic environments.  In the last few months, we’ve been speaking to more and more customers who are using Iron for large ML and AI workloads, often breaking them into distinct types of work units that require different levels of GPU, CPU and memory requirements.

Congratulations to the winners of the contest and all those that participated!  It looked incredibly challenging.  If you have any questions about utilizing GPU’s, machine learning, artificial intelligence, or any other computational heavy lifting jobs using Iron, feel free to contact us at as we’ll be happy to chat.

Full Circle and Ramping up at was recently acquired by Xenon Ventures, a private equity, and venture capital firm. Xenon Ventures is headed by Jonathan Siegel, a serial entrepreneur who has founded many popular software services and has made just as many successful acquisitions.

Here comes the full circle. What may not know, is that Jonathan was’s first customer and investor back in 2010 prior to’s creation. Jonathan was client and friend of the founders’ consulting business prior to and encouraged the founders to transform their consulting service into a product.

In 2011 the first version of IronWorker was launched and the serverless revolution began. After pioneering this space, has grown significantly adding products like IronMQ, IronCache, and our latest development of our Open Source product, IronFunctions. This success is due all of our amazing customers and partners! Thank You!!

New and old faces

You may be seeing a new name fly around a bit as well.  I’ll (Dylan Stamat) be joining as General Manager and moving Iron forward. A little about me: I’ve been a personal friend to the founders, I was a co-founder at RightSignature (, founded one of the first HIPAA compliant companies to run on AWS (, was previously the CTO at a large technology consultancy company (ELC Technologies), a Ruby on Rails contributor, a committer to Ehcache, and a big fan of Erlang and Golang.

You will also see and hear from many other familiar faces at – Roman Kononov, Director of Engineering who has been leading our engineering office in Bishkek, Kyrgyzstan since 2011. Nikesh Shah, Director of Business Development and Marketing, and other various new and old members from our globally distributed teams.

As of now – we’ve added 2 new offices to Iron: one in Las Vegas, Nevada, the other in Tokyo, Japan. We’ve hired new Engineers and Customer Success and are continuing to hire. Let us know if you have any interest in joining our team!

What’s to expect moving forward?

New graphs providing quick ways to visualize historical worker concurrency

The short answer is, things are going to get a lot better.  We’ve been very busy since the acquisition.  There have been a lot of bug fixes, improvements to internal tooling, and we’ve added concurrency graphs to help provide more insight into the system.

Near term, we are committed to continuing and ramping up development in our entire product line. This includes better performance and reliability, a new user interface, granular metrics reporting such as concurrency graphs, streamlining customer support and putting new systems in place to better track feature requests and bug reports, and bug fixes throughout our web applications.

Long term, as it relates to products, we are being guided by 2 core principles:
Open Source, and Hybrid Cloud Deployments.

I’m excited about the future, and getting to know all of you! We will have more exciting news to announce in the coming months.  Please feel to reach out to us and stay tuned!

Top 10 Uses For A Message Queue

We’ve been working with, building, and evangelising message queues for the last year, and it’s no secret that we think they’re awesome. We believe message queues are a vital component to any architecture or application, and here are ten reasons why:

Top 10 Uses of a Worker System

A worker system is an essential part of any production-scale cloud application. The ability to run tasks asynchronously in the background, process tasks concurrently at scale, or schedule jobs to run on regular schedules is crucial for handling the types of workloads and processing demands common in a distributed application.

At, we’re all about scaling workloads and performing work asynchronously and we hear from our customers on a continuous basis. Almost every customer has a story on how they use the IronWorker platform to get greater agility, eliminate complexity, or just get things done. We wanted to share a number of these examples so that other developers have answers to the simple question “How do I use a worker system?” or “What can I do with a task queue?” (more…)
