Widely adopted by both developers and organisations, Kubeflow is an MLOps platform that runs on Kubernetes and automates machine learning (ML) workloads. It covers the entire ML lifecycle, enabling data scientists and machine learning engineers to develop and deploy ML models. Kubeflow is designed as a suite of leading open source projects that enable different capabilities such as model serving, training or hypertuning optimisations. At Canonical, we deliver Charmed Kubeflow – an official distribution of the upstream solution with additional security maintenance, tool integrations, and enterprise support and managed services – so we know a thing or two about the project. In our experience, one of the most important concepts to understand with respect to both Kubeflow itself and the broader ML lifecycle is machine learning pipelines. Taking advantage of pipelines is the best way to effectively deploy models at scale in production, so let’s break down this critical component in the MLOps landscape. What is an ML pipeline? A machine learning pipeline is an important component of ML systems, ensuring simplified experimentation and capability to take models to production. They are a series of steps that automate how ML models are created, in order to streamline the workflow,development and deployment. ML pipelines simplify the complexity of the end-to-end ML lifecycle, helping professionals to develop and deploy models. Amongst their benefits, ML pipelines ensure scalability thanks to their ability to handle large volumes of data while supporting collaboration and reproducibility. A core value of MLOps platforms such as Kubeflow is that they enable professionals to build and maintain ML pipelines. What is Kubeflow Pipelines? Kubeflow Pipelines or KFP is the heart of Kubeflow. It is a Kubeflow component that enables the creation of ML pipelines. It is used to help you build and deploy container-based ML workflows that are portable and scalable. The main goals of Kubeflow Pipelines are to simplify the following processes: Orchestration of the end-to-end ML pipelines Experimentation with various ideas and techniques Experiment management Reuse of components and pipelines to enable users to quickly put together end-to-end solutions without having to re-build each time Components of Kubeflow Pipelines Kubeflow Pipelines is part of the Kubeflow project. It can be used as part of the project or as an independent tool. It is made of 3 main components: User interface (UI) for managing and tracking experiments, jobs, and runs Engine for scheduling multi-step ML workflows SDK for defining and manipulating pipelines and components Kubeflow Pipelines use cases Kubeflow Pipelines is typically most useful for advanced users of Kubeflow or professionals who already have experience with machine learning. You don’t necessarily need KFP in the experimentation phase of the ML journey, but it becomes useful when you want to take yourmodels to production. The main use cases for KFP include: Workflow automation: Data scientists and machine learning engineers often perform a lot of the initial experimentation phase manually to better understand optimisation possibilities and quickly iterate. But once they have defined their workflow, they can use KFP to automate the process and save time. Model deployment to production: Models are usually compiled in a binary file. Traditionally, for the model to be loaded to a server where the requirements for inference are met, this file would be manually copied to the machine that hosts the application. KFP simplifies this process by enabling you to build automated pipelines to multiple applications or servers. Model maintenance and updates: The ML lifecycle is an iterative process and models need to be updated periodically. KFP helps users run updates and rollbacks across multiple applications or servers. Once the model is updated in one place and the update transaction is complete, KFP ensures the update is quickly applied to all client applications. Multi-tenant ML environment: Organisations often have large data and ML teams that need to share their resources. KFP enables simple and effective sharing of the environment, where each collaborator gets an isolated environment. It is then utilised by the K8s cluster and tools such as Volcano to schedule resources or manage containers. This helps professionals isolate workflows and keep track of pending and running jobs for each collaborator. Benefits of KFP Among machine learning specialists, Kubeflow Pipelines is widely adopted for a number of reasons. The most important benefits of KFP include: Streamlined workflow automation: Kubeflow Pipelines allows users to define the machine learning pipelines as a sequence of steps, each with its input, output, and dependencies. This leads to streamlining the machine learning workflows, and reduces the overhead and complexity of managing and executing your pipelines. Improved collaboration: Kubeflow Pipelines provides a central and shared platform for data scientists, machine learning engineers, and IT operations teams to collaborate on machine learning projects. It allows them to share pipelines and artifacts with others, and enables the tracking and monitoring of the pipelines across the entire organisation. Enhanced performance and scalability: Kubeflow Pipelines runs on Kubernetes, which provides a scalable and flexible infrastructure for running machine learning pipelines and models. This allows you to easily scale up and down the pipelines, and ensure that your pipelines are performant and reliable. Resource optimisation: KFP is a cloud native application, so it can leverage the resource schedulers that Kubernetes platforms provide. This leads to optimised usage of the existing resources and faster project delivery. Extensive support for popular machine learning frameworks: KFP provides built-in support for popular machine learning frameworks like TensorFlow, PyTorch, and XGBoost, as well as a rich ecosystem of integrations and plugins for other tools and services. Charmed Kubeflow goes a step further and enables additional integrations with tools and frameworks such as NVIDIA NGC Containers, Triton Inference Server and MLflow. Whereas Kubeflow Pipelines is a feature-rich tool, it still raises some challenges for beginners. It comes with a steep learning curve and there is limited documentation available. Since it is a fully open source tool, there is a big community that can help beginners, but it can be frustrating at times. You can alleviate these challenges by taking advantage of enterprise support or managed services from organisations which distribute Kubeflow. Architecture of Kubeflow Pipelines Kubeflow Pipelines is a complex component with capabilities that unblock users and enable them to automate their workflows and reduce their time spent on manual tasks. The following architecture depicts these capabilities: source: Kubeflow community As the diagram illustrates, users can interact with KFP either through the user interface or through development tools such as Notebooks. Initially, users create components or specify a pipeline using the Kubeflow Pipelines domain-specific language (DSL). Once defined, the compiler transforms the Python code into a YAML static configuration. Then, the Pipeline Service creates a pipeline run from the static configuration. It calls the server of Kubernetes API for creating the necessary Kubernetes resources (CRDs) to run the pipeline. If you have a resource scheduler integrated, you can use it to run the pipeline when resources are available or at a desired time. To complete the pipeline, the containers are executed within the Kubernetes pods, using orchestration controllers. Two types of data can be stored. The first type is metadata, which includes experiments, jobs, pipeline runs, and single scalar metrics. The second type is artefacts, which includes pipeline packages, views, and large-scale metrics (time series). Metadata is stored in a MySQL database, whereas artefacts are stored within MinIO. Storing them in an external component also enables portability, so artefacts can be migrated to different clusters or environments. Kubernetes resources created by the Pipeline Service are monitored by the Persistence Agent. To enable reproducibility, the input and output of the containers are recorded. It enables professionals to use the configurations and replicates different tasks, also being able to check if the results match. They consist of parameters or data artefact URIs and are seen as metadata. The Pipeline web server enables users to get a visual understanding of the steps from the Kubeflow Pipelines. It presents various information, including list of pipelines currently running, history of pipeline execution, data artefacts and logs for debugging. Get started with Kubeflow Pipelines In order to access Kubefow Pipelines, users can either deploy them independently or as part of the Kubeflow project. For simplified deployment, we recommend using Charmed Kubeflow. Deploy Charmed Kubeflow following the tutorial. You can do it on any environment, including public cloud or on-prem. Ensure that you have enough resources available, so you do not bump into problems along the way Access the Kubeflow dashboard. In case you are accessing it from a VM or from a public cloud, please ensure that you change the SOCKs proxy settings. There you will have different options, including to upload an existing pipeline or create a new one. Clone this repository from Github which contains a simple example of how to use some of the components of Kubeflow Access the examples from the Notebook. There are several pipelines created which you can run, edit or play with. Of course, they are just examples. In order to build your own pipeline, check the official documentation of the Kubeflow project.

Machine learning is increasingly essential for businesses of all sizes. However, building, deploying, and continuously training ML models can be complex and time-consuming. That's where Kubeflow Pipelines (KFP) comes in. Over the years, we have seen increasing adoption of KFP. KFP provides an ecosystem to compose, deploy and manage reusable end-to-end machine learning workflows, making it a no-lock-in hybrid solution from prototyping to production. So we are excited to announce the release of KFP v2. This blog post will take you through what's new in KFP v2. Wait, what’s Kubeflow?The Kubeflow ecosystem was initially open-sourced by Google and partners in 2018 to extend Kubernetes for machine learning. In 2019 Kubeflow Pipelines was introduced as a standalone component of that ecosystem for defining and orchestrating MLOps workflows to continuously train models via the execution of a directed acyclic graph (DAG) of container images. KFP provides a Python SDK and domain-specific language (DSL) for defining a pipeline, and backend and frontend services for running and scheduling pipelines on your Kubernetes cluster of choice. Since its launch, KFP has accrued a rich community of orchestration options (e.g., Vertex AI Pipelines) and pre-built components (e.g., Google Cloud Pipeline Components). What’s new in KFP v2?KFP v2 has several major improvements. This section will highlight some of them. 1. An improved Python-based authoring experience for components and pipelines The new @dsl.component and @dsl.container_component decorators simplify and standardize the component authoring experience while improving readability. Additionally, Python docstrings are automatically propagated to the pipeline specification, improving the understandability and reuse of the pipelines you author. 2. A new Argo-independentpipeline definition that enables compile and run anywhere: executable components, nested pipelines, and potentially, new orchestrator options KFP v2’s updated intermediate representation (IR) includes additional details that makes the pipeline executable by any backend (not just Argo). Another big benefit is that you can now compile and run individual components (not just pipelines), and nest pipelines as a component of a larger pipeline. 3. An uplifted Workflow GUI KFP v2 introduces several improvements to help visualize ML workflows. KFP now surfaces input and output artifacts (e.g., datasets, models, and metrics) as first-class nodes in the DAG visualization. This enables users to view how artifacts are used and produced in the workflow and metadata describing them. Nested pipelines are now supported and represented as a sub-DAG. Users can now zoom in the workflow canvas, which greatly improves usability for large pipelines. And there’s more: new run comparison, run cloning, and listing Artifacts and Executions features. 4. First class support for ML metadata (MLMD) artifacts and lineage Previously MLMD was an optional integration. In KFP v2, MLMD is a required dependency. This enables KFP to provide (1) rich lineage tracking and visualization out-of-the-box and eventually (2) custom artifact schemas for strict type checking of component interfaces and improved visualization of custom artifacts. 5.Increased security due to upgrading upstream dependencies to their latest major version (e.g. Argo, MinIO, MySQL, Envoy Proxy, and MLMD) We have taken the opportunity afforded to us by this major version bump to upgrade many upstream dependencies to their latest major version. The KFP v2 backend is completely backwards-compatible with v1 (v1 APIs still exist), so we recommend that all KFP backend users upgrade to KFP v2. These changes were discussed in greater depth during the 2022 Kubeflow Summit. What’s next?Have a look at this notebook to learn more about KFP v2 and how to use it with Vertex AI Pipelines. SDK users, including Vertex AI Pipelines users, can find migration guidance at: Migrate from KFP SDK v1. Open source backend and frontend users can find upgrade instructions for their KFP clusters at: Installation. KFP has come a long way since 2019, and proven itself at scale in powering complex MLOps workflow orchestration. We recommend upgrading to KFP v2 without delay to enjoy all the benefits it provides. We greatly appreciate your feedback via GitHub, support for, and contributions to KFP. You can find KFP’s contribution guide at CONTRIBUTING.md.
