Releasing ML systems into production is harder than traditional software. They are nondeterministic, hard to test, hard to explain, and hard to improve. You aren’t finished when you find your first working model; you also need to think about things like integration, testing, deployment, scaling, and monitoring. What’s more, after launch, you want to continuously adapt and improve your model to respond to the changing environment.

ThoughtWorks pioneered CD, and have now further developed it to overcome the challenges associated with ML systems, and calls this new approach continuous delivery for machine learning (CD4ML). CD4ML is a software engineering approach in which a cross-functional team produces ML applications based on code, data, and models in small and safe increments that can be reproduced and reliably released at any time in short adaptation cycles.

Danilo Sato demonstrates how to apply CD4ML using a real ML application in a live scenario.


  • Create your deployment pipelines
  • Version your model training workflow to make it reproducible
  • Improve your model in a development environment, test its performance, and depending on the outcome, automatically deploy the new model into a production environment
  • Track model performance across various experiments
  • Monitor and observe your model in production to close the data feedback loop.

The tech stack is Python with scikit-learn, data science version control (DVC), MLflow, GoCD, Docker, Git, Elasticsearch, FluentD, Kibana, and Google Cloud Platform.

Prerequisite knowledge

  • A basic understanding of developing ML models (preferably in Python), source control with Git, and using Docker for local development

Materials or downloads needed in advance

  • A laptop with a GitHub account and Docker installed

What you'll learn

  • Understand the importance of CD4ML, its technical components, and experience a specific implementation using open source tools and the public cloud to automate the end-to-end lifecycle of ML applications
