In the last several years, machine learning has been taking the world by storm: more and more organizations from across various, even the seemingly most incompatible, industries are adopting it to optimize production processes, for improving customer experience, fraud detection, and security purposes, and even for diagnosing and treating diseases. But, as this adoption has grown, it has become increasingly important to manage the process of developing, deploying, and maintaining machine learning models at scale – this is called MLOps. MLOps involves various tasks, like managing data, training models, and monitoring performance. Naturally, numerous open source and proprietary MLOps tools made these tasks easier.
In this article, we’ll look at some of the most popular open source MLOps tools available today and give a rundown of what they can do. For your convenience, we’ve broken the tools down into categories based on what features they have to offer to help data scientists and machine learning engineers work more efficiently.
