Remote access to SAP
Remote access to Message Broker Server
System Requirements – Message Broker
Any Windows Server with .NET 4.7.2 Framework
RAM: minimum 1 GB allocatable
HDD: the program itself has minimal disk space requirements. What can grow big and quickly take several gigabytes are the log files. Therefore 50GB above the system requirements are recommended. Log files retention policy should be considered and implemented to keep the HDD requirements lower
remote access: installation and administration of Message Broker requires a (remote or physical) access to the machine, with administrative rights (necessary to install/update program binaries and start/stop windows service)
Network encryption and the (lack of) maintenance of certificates and algorithms to do those can cause connectivity issues. Note that especially root certification authorities should be updated regularly. In case of connection issues to FSM Cloud due to untrusted TLS certificate please refer to the following SAP note: https://launchpad.support.sap.com/#/notes/2943007.
System Requirements – Cloud Manager
An instance of Windows with .NET 4.7.2 Framework. Windows Server is not needed.
Network connectivity
The following firewall ports have to be opened in order to make E4C work:
SAP -> Message Broker host: one port has to be opened, the port number is arbitrary and it depends on configuration of Message Broker web service. Default 9990
Message Broker -> SAP host: one port has to be opened, the port number depends on SAP Internet Communication Manager Configuration. Default is (8000 + SAP system number).
Message Broker -> Coresuite Cloud host (intranet -> internet): currently one port need to be opened: 443 for HTTPS communication.
Note that although E4C handles bidirectional communication, from the point of view of the network connectivity, all connections between E4C and Coresystems Cloud are outgoing connections. I.e. no inbound connections/ports (from internet to intranet) on firewall need to be opened to enable receiving of inbound messages.
