Types of SAP NetWeaver System deployment

Within deployment of SAP NetWeaver we recognize below types of deployments. Below terminology is at some extend similar to former NetWeaver terminology called as “usage types” or component type. I wrote about the NetWeaver usage types here.
Within SAP NetWeaver 7.5 (a successor of 7.4) there were changes into how the NetWeaver system is supposed to be upgraded in case they are deployed as per its different type. Always refer to SAP Notes as per the type of your deployment with regards to the upgrade of the system.

In general a hub is a concept that refers to a node with number of links. Similarly in SAP NetWeaver terminology the HUB it is a system whose purpose is to connect multiple systems in a system landscape and provide services centrally.
So the NetWeaver system is hub system in case multiple business applications are deployed upon it. The business applications themselves may run against multiple application back-end systems (e.g. ECC-Server, CRM, SRM, etc.).
Here are some examples of SAP NetWeaver hubs:
·         SAP NetWeaver Identity Management (IdM)
·         SAP Enterprise Portal (EP)
·         SAP Business Warehouse (BW)
·         SAP Process Orchestration (PO)


In case the NetWeaver system is exclusively dedicated to one back-end system then we call it side car system.
