About the Core category

The Core Services (CS) Layer separates the north side and south side layers at the edge. Core services include the following components:

  • Core data: a persistence repository and associated management service for data collected from the south side objects.
  • Command: a service that facilitates and controls actuation requests from the north side to the south side.
  • Metadata: a repository and associated management service of metadata about the objects that are connected to EdgeX Foundry. Provides the capability to provision new devices and pair them with their owning device services.
  • Registry and Configuration: provides other EdgeX Foundry microservices with information about associated services within EdgeX Foundry and microservices configuration properties (i.e. - a repository of initialization values).
