Why look beyond Kubeflow
Kubeflow provides a comprehensive, open-source platform for deploying and managing machine learning (ML) workflows on Kubernetes [1]. Its strength lies in leveraging Kubernetes' orchestration capabilities, offering components for data processing, model training, hyperparameter tuning, and serving. This makes it a powerful choice for organizations with existing Kubernetes infrastructure and a need for highly scalable, portable ML operations.
However, Kubeflow's deep integration with Kubernetes also presents its primary challenge: operational complexity. Teams without significant Kubernetes expertise may find the initial setup, configuration, and ongoing maintenance demanding. Managing Kubernetes clusters, understanding containerization, and debugging distributed ML jobs within this environment requires specialized skills. Furthermore, while Kubeflow offers extensive functionality, some teams may prefer more opinionated, managed solutions that abstract away infrastructure concerns, or lighter-weight tools focused on specific aspects of the ML lifecycle, such as experiment tracking or model deployment, without the overhead of a full MLOps platform.
