Gateway is a service responsible for routing requests to/from or between Servables and Applications and validating these requests for matching a Model's/Application signature.

The Gateway maps a model’s name to a corresponding container. Whenever it receives a request via HTTP API, GRPC, or Kafka Streams, it communicates with that container via the gRPC protocol.


Manager is responsible for:

  • Building a Docker Image from your ML model for future deployment

  • Storing these images inside a Docker Registry deployed alongside with

    manager service

  • Versioning these images as Model Versions

  • Creating running instances of these Model Versions called Servables

    inside Kubernetes cluster

  • Combining multiple Model Versions into a linear graph with a single

    endpoint called Application
