SageMaker Pipelines Overview

An Amazon SageMaker Model Building Pipelines pipeline is a series of interconnected steps that are defined using the Pipelines SDK. You can also build your pipeline without the SDK using the pipeline definition JSON schema. This pipeline definition encodes a pipeline using a directed acyclic graph (DAG) that can be exported as a JSON definition. This DAG gives information on the requirements for and relationships between each step of your pipeline. The structure of a pipeline's DAG is determined by the data dependencies between steps. These data dependencies are created when the properties of a step's output are passed as the input to another step. The following image is an example of a pipeline DAG:

The following topics describe fundamental SageMaker Pipelines concepts. For a tutorial describing the implementation of these concepts, see Create and Manage SageMaker Pipelines.
