MLRun is made up of multiple services: a UI, orchestration, security, RBAC, SSO, and more. These services are provided through multiple types of components, with operators being one of them. MLRun uses operators when launching services like a Spark job or a real-time serving function. These operators take the requests and turn them into live services.MLRun supports eight different operators: Nuclio for real-time, operators for multi-stage graphs, an operator for online multi-state graphical serving, a Spark operator, a Dask operator, and more. These operators are pluggable, which provides flexibility for adding more in the future. Operators are deployed as Helm charts, but can also support cloud formation.
