About this Episode


Building a machine learning model can be difficult, but that is only half of the battle. Having a perfect model is only useful if you are able to get it into production. In this episode Stepan Pushkarev, founder of Hydrosphere, explains why deploying and maintaining machine learning projects in production is different from regular software projects and the challenges that they bring. He also describes the Hydrosphere platform, and how the different components work together to manage the full machine learning lifecycle of model deployment and retraining. This was a useful conversation to get a better understanding of the unique difficulties that exist for machine learning projects.


  • Hello and welcome to the Data Engineering Podcast, the show about modern data management
  • When you’re ready to build your next pipeline, or want to test out the projects you hear about on the show, you’ll need somewhere to deploy it, so check out our friends at Linode. With 200Gbit private networking, scalable shared block storage, and a 40Gbit public network, you’ve got everything you need to run a fast, reliable, and bullet-proof data platform. If you need global distribution, they’ve got that covered too with world-wide datacenters including new ones in Toronto and Mumbai. And for your machine learning workloads, they just announced dedicated CPU instances. Go to today to get a $20 credit and launch a new server in under a minute. And don’t forget to thank them for their continued support of this show!
  • And to keep track of how your team is progressing on building new pipelines and tuning their workflows, you need a project management system designed by engineers, for engineers. Clubhouse lets you craft a workflow that fits your style, including per-team tasks, cross-project epics, a large suite of pre-built integrations, and a simple API for crafting your own. With such an intuitive tool it’s easy to make sure that everyone in the business is on the same page.

  • Introduction
  • How did you get involved in the area of data management?
  • Can you start by explaining what Hydrosphere is and share its origin story?
  • In your experience, what are the most challenging or complicated aspects of managing machine learning models in a production context?
    • How does it differ from deployment and maintenance of a regular software application?
  • Can you describe how Hydrosphere is architected and how the different components of the stack fit together?
  • For someone who is using Hydrosphere in their production workflow, what would that look like?
    • What is the difference in interaction with Hydrosphere for different roles within a data team?
  • What are some of the types of metrics that you monitor to determine when and how to retrain deployed models?
    • Which metrics do you track for testing and verifying the health of the data?
  • What are the factors that contribute to model degradation in production and how do you incorporate contextual feedback into the training cycle to counteract them?
  • How has the landscape and sophistication for real world usability of machine learning changed since you first began working on Hydrosphere?
    • How has that influenced the design and direction of Hydrosphere, both as a project and a business?
    • How has the design of Hydrosphere evolved since you first began working on it?
