Coinbase Logo


Coinbase is a secure digital currency exchange platform that makes it easy to buy, sell, and store cryptocurrency like Bitcoin, Ethereum, and Litecoin. As of 2017, Coinbase is the largest bitcoin broker in the world and serves users in 33 countries. Coinbase has a high performing engineering organization. They deploy hundreds of times per day across hundreds of projects, release new features from idea to launch in under an hour, and sustain low failure rates. This is possible because most of their change management and deployment processes are automated and their engineers have adopted a DevOps culture.

A key part of that automation is their secure, automated deployment pipeline, Odin. Odin takes a description of a project release and then safely and securely launches it into AWS. Coinbase automated Odin using AWS Step Functions, allowing them to deploy 12-factor-applications to AWS easily, reliably and securely. Step Functions provided the tools for reliability and end-to-end visibility out of the box, with a serverless operating model that doesn’t require any infrastructure to be provisioned or managed. Designing Odin as a Step Functions state machine lets Coinbase visually monitor the progress of the deployment, and audit each deployment step by step. With new insight into the reasons why services were failing, Coinbase was able to improve their rate of successful mission critical deployments from 90% to 97%. The visibility provided to engineers allowed them to diagnose and resolve their own issues quickly, and reduced the number of support tickets related to unsuccessful deployments.

"If a team focuses on building quality automation into their workflows, stability follows. By building quality automation with services like AWS Step Functions, Coinbase avoids trading speed for stability, and instead we get both."

Graham Jenson, Infrastructure Engineer – Coinbase

Cox Automotive Logo

Cox Automotive

Cox Automotive Inc. makes buying, selling, owning and using cars easier. To support digital advertising, they wanted to increase the volume and quality of their machine learning prediction models. However, they were concerned that their models might drift over time, leading to poor decisions. Injecting Data Scientist oversight into the model retraining process was the best solution, but the challenge was to to do so without slowing down the Decision Science team.

Cox Automotive decided to automate their ML model delivery workflow with AWS, including a model approval pipeline coordinated by AWS Step Functions. Once models are retrained using Amazon SageMaker, the output artifacts and diagnostics are uploaded to Amazon S3, which triggers Step Functions to run a model approval workflow. An email is sent to a Data Scientist, who reviews the model and clicks either “Approve” or “Reject”. If approved, Step Functions sends the artifacts to a destination S3 bucket along with an Amazon SNS notification indicating that the new model is ready for consumption.

Investing in automation has given both teams time to work on higher value activities. Cox Automotive now has a reusable, automated process that allows them to spend more time making more accurate models, and less time building deployment pipelines.

"Using services like Amazon SageMaker and AWS Step Functions to automate model deployment has enabled us to deliver recurring quality, mostly-automated models to the business with minimal human intervention and overhead."

Jeremy Irwin, Lead Solutions Architect – Cox Automotive

CyberGRX Logo


CyberGRX creates a risk management platform that pinpoints, measures, and prioritizes third-party cyber risks, transforming third-party cyber risk management for enterprises all over the world. It chose to build on Amazon Web Services (AWS) due to the simplicity of deployment and how the design mapped easily to the company's existing workflows.

"We needed to run massive parallel computations on our Bayesian network algorithm and decided to use the AWS Step Functions distributed map state because it provided the capability to scale in a way that was unattainable before. Using Distributed Map, we were able to process the entire exchange, 227,000 companies worth of data—57 billion data points—in under an hour, which previously took us over 8 days of processing. Not only did it save us a massive amount of manpower time, it also made it far less expensive."

Charles Burton, Director, Senior Software Engineer – CyberGRX

Driver and Vehicle Licensing Agency Logo

Driver and Vehicle Licensing Agency

Driver and Vehicle Licensing Agency (DVLA) is an executive agency of the Department of Transport in the United Kingdom. It holds more than 50 million driver records and more than 40 million vehicle records and collects over £7 billion a year in Vehicle Excise Duty (VED). The DVLA prioritizes developing services around its customers’ needs while ensuring data protection. The DVLA chose Amazon Web Services (AWS) to help it reduce operational complexity and costs by leveraging the wide range of managed services AWS offers, particularly Amazon Elastic Kubernetes Service (Amazon EKS).
“At DVLA we need to manage UK driving license applications across internal APIs such as payments, notifications, and reporting, typically running in separate accounts or Amazon EKS clusters. We also needed to support long-running human tasks, like uploading customers’ photographs. AWS Step Functions allows us to define and run complex process orchestration workflows on a scalable managed service across all our accounts. We’ve multiple product teams building application processing workflows on a shared platform powered by Step Functions. Using this approach, we’ve rapidly developed and deployed an entirely new service for digital photo upload and processing, having processed over 800,000 driving license applications to date.”
Tom Collins, Head of Software Engineering - DVLA
Home 24 Logo

Home 24

Home24 is a European market leader in online shopping for home and living products. They run their entire data analytics platform on AWS, analyzing multiple data sources including market data, social media, search analytics, and internal ERP systems. They used AWS Step Functions to build a flexible, long-running serverless ELT pipeline. Their data engineers can now quickly integrate new data sources and modify pipelines to perform new transformations and analytics. The platform can also withstand API failures since Step Functions automatically retries if service APIs are unavailable.
Outsystems Logo


Outsystems offers a low-code visual development platform for rapid application development. They wanted to ensure that their customers wouldn’t run out of disk space—without having to over-provision storage. To do this, Outsystems developed an automatic resizing process with AWS Step Functions, which they exposed as a serverless microservice behind Amazon API Gateway. This made it possible for Outsystems to change their default database from 1024 GB to 400 GB, reducing storage costs by 60%. These databases could then be resized as needed to meet customer demand.
Xylem Logo


Xylem is a leading global water technology company committed to developing innovative technology solutions to the world’s water challenges. To perform analytics, Xylem was using a Hadoop-based, on-premises data lake to store massive amounts of electric, water, and gas metering data. However, this solution limited their data analysis capabilities and was not flexible enough to allow for the addition of new projects. Data processing was taking four to five hours each day, and if they added new customers, up to several days.

By moving the Xylem Data Lake to an AWS-based platform leveraging AWS Batch, AWS Step Functions, and AWS Lambda, the Xylem data team was able to dramatically expand their data analytics capabilities. Xylem feeds each input file to a Step Functions state machine, which then validates the file, tracks metadata and finally, launches and monitors an AWS Batch job that processes the data. Each state machine runs independently and in parallel. The AWS Batch jobs allocate containers automatically, and Xylem can now parse thousands of files simultaneously, without having to worry about jobs competing for resources. As a result, Xylem has reduced data processing time from 20 hours to only two hours – regardless of the size of the dataset.

"Using AWS Step Functions as part of the Xylem Data Lake has transformed our pace of innovation. We can now develop internal and external analytics projects with fewer handoffs to other engineers, fewer interrupts with DevOps, and with more technologies than we ever thought possible."

Mitchell Hensley, Vice President, Software Strategy – Xylem


Thomson Reuters

Thomson Reuters Corporation is a Canadian multinational mass media and information firm. Like many media companies, they have a high volume of incoming video to process. They needed to transcode over 350 news video clips per day into 14 formats each. Being a trusted provider of news and information, they also needed to do this as quickly as possible. Their files are all in the same format, but they vary wildly in length. To tackle this wide variance, Thomson Reuters developed a serverless split video transcoding application using AWS Step Functions. They can now process video segments in parallel, and are able to process a typical video in 2 minutes instead of 20 minutes.
yelp logo


Yelp is focused on local businesses - they’re around to help you find what you're looking for, whatever city you happen to be in. Yelp wanted to modernize a business-critical subscription billing process. The code had grown over the past 10 years, so refactoring seemed hard, expensive and risky. Yelp used Step Functions to approach the transition as a series of small, incremental steps. First, Yelp simply moved the entire process inside Step Functions, which immediately gave them the benefits of a well-defined API and built-in error handling. Over time, Yelp continued to gradually break down the code into more friendly “bite-sized” pieces, and was able to move one task at a time into serverless AWS Lambda functions or containers with minimal effort and no change to code.
