Kubeflow is an open-source platform for machine learning and MLOps on Kubernetes introduced by Google. The different stages in a typical machine learning lifecycle are represented with different software components in Kubeflow, including model development (Kubeflow Notebooks [4] ), model training (Kubeflow Pipelines , [5] Kubeflow Training Operator [6] ), model serving (KServe [lower-alpha 1] [7] ), and automated machine learning (Katib [8] ).

Contents

Each component of Kubeflow can be deployed separately, and it is not a requirement to deploy every component. [9]

History

The Kubeflow project was first announced at KubeCon + CloudNativeCon North America 2017 by Google engineers David Aronchick, Jeremy Lewi, and Vishnu Kannan [10] to address a perceived lack of flexible options for building production-ready machine learning systems. [11] The project has also stated it began as a way for Google to open-source how they ran TensorFlow internally. [12]

The first release of Kubeflow (Kubeflow 0.1) was announced at KubeCon + CloudNativeCon Europe 2018. [13] [14] Kubeflow 1.0 was released in March 2020 via a public blog post announcing that many Kubeflow components were graduating to a "stable status", indicating they were now ready for production usage. [15]

In October 2022, Google announced that the Kubeflow project had applied to join the Cloud Native Computing Foundation. [16] [17] In July 2023, the foundation voted to accept Kubeflow as an incubating stage project. [18] [19]

Components

Kubeflow Notebooks for model development

Machine learning models are developed in the notebooks component called Kubeflow Notebooks. The component runs web-based development environments inside a Kubernetes cluster, with native support for Jupyter Notebook, Visual Studio Code, and RStudio. [20]

Kubeflow Pipelines for model training

Once developed, models are trained in the Kubeflow Pipelines component. The component acts as a platform for building and deploying portable, scalable machine learning workflows based on Docker containers. [21] Google Cloud Platform has adopted the Kubeflow Pipelines DSL within its Vertex AI Pipelines product. [22]

Kubeflow Training Operator for model training

For certain machine learning models and libraries, the Kubeflow Training Operator component provides Kubernetes custom resources support. The component runs distributed or non-distributed TensorFlow, PyTorch, Apache MXNet, XGBoost, and MPI training jobs on Kubernetes. [6]

KServe for model serving

The KServe component (previously named KFServing [23] ) provides Kubernetes custom resources for serving machine learning models on arbitrary frameworks including TensorFlow, XGBoost, scikit-learn, PyTorch, and ONNX. [24] KServe was developed collaboratively by Google, IBM, Bloomberg, NVIDIA, and Seldon. [23] Publicly disclosed adopters of KServe include Bloomberg, [25] Gojek, [26] the Wikimedia Foundation, [27] and others. [28]

Katib for automated machine learning

Lastly, Kubeflow includes a component for automated training and development of machine learning models, the Katib component. It is described as a Kubernetes-native project and features hyperparameter tuning, early stopping, and neural architecture search. [29]

Cilium is a cloud native technology for networking, observability, and security. It is based on the kernel technology eBPF, originally for better networking performance, and now leverages many additional features for different use cases. The core networking component has evolved from only providing a flat Layer 3 network for containers to including advanced networking features, like BGP and Service mesh, within a Kubernetes cluster, across multiple clusters, and connecting with the world outside Kubernetes. Hubble was created as the network observability component and Tetragon was later added for security observability and runtime enforcement. Cilium runs on Linux and is one of the first eBPF applications being ported to Microsoft Windows through the eBPF on Windows project.
