Configuration Overview
======================
+SD-Core has been developed with a cloud-based deployment and consumption model as
+its foundation. It has a rich and extensible set of APIs to allow for runtime configurability of
+subscriber management, access management, session management, and network slice
+management. This configuration may be conducted via ONF’s Runtime Operational Control
+(ROC) platform directly for consumption as a cloud-managed service, or the APIs can be
+used by third-party automation and management platforms.
