Platform Architecture¶
CRD Ownership Map¶
The platform defines 45 CRDs. Each CRD is owned by the component that declares it.
| Owner | CRDs | Count |
|---|---|---|
| codeflare-operator | AppWrapper | 1 |
| data-science-pipelines | CompositeController, ControllerRevision, DecoratorController | 3 |
| data-science-pipelines-operator | DataSciencePipelinesApplication, Pipeline, PipelineVersion, ScheduledWorkflow | 4 |
| kserve | ClusterServingRuntime, ClusterStorageContainer, InferenceGraph, InferenceService, LLMInferenceService, LLMInferenceServiceConfig, LocalModelCache, LocalModelNamespaceCache, LocalModelNode, LocalModelNodeGroup, ServingRuntime, TrainedModel | 12 |
| llama-stack-k8s-operator | LlamaStackDistribution | 1 |
| mlflow-operator | MLflow, MLflowConfig | 2 |
| model-registry-operator | ModelRegistry | 1 |
| modelmesh-serving | ClusterServingRuntime, InferenceService, Predictor, ServingRuntime | 4 |
| odh-model-controller | Account | 1 |
| spark-operator | ScheduledSparkApplication, SparkApplication, SparkConnect | 3 |
| trainer | ClusterTrainingRuntime, TrainJob, TrainingRuntime | 3 |
| training-operator | JAXJob, MPIJob, PaddleJob, PyTorchJob, TFJob, XGBoostJob | 6 |
| workload-variant-autoscaler | VariantAutoscaling | 1 |
Cross-Component Dependencies¶
