_ Those nice on-premise SAP systems are

_ In fact, they’re behind several firewalls
_ We’d like to keep it that way
_ This is the hybrid cloud connectivity
challenge

SERVICE CHANNELS
17
_ Service channels provide access to cloud
resources from on-premise
_ Supported resources so far:
_ HANA databases
_ Virtual machines
_ S/4HANA Cloud RFCs
_ Cloud Connector creates an endpoint,
that on-premise tools and applications
talk to
