I would like to know how HCP is hosted? Is it only at SAP Data Centers? Also, does HCI only run as an integration services on HCP? So, how does the architecture look if I have a S/4 Instance running in a private, on-prem or public cloud and have on-prem 3rd party apps as well. Does HCP/HCI sit on a different Cloud environment? thx
Today HCP is hosted in SAP Data Centers(DC). We have plans to use non-SAP DCs in future. Yes HCP Integration service (HCI) is part of HCP.
For S/4 on-prem/public cloud integrating with SAP apps (Successfactors, Ariba etc) or 3rd party apps - architecture is that HCP integration service would come between S/4 and the app that is being integrated. Naturally the integration service sits on SAP DCs where HCP is hosted.
