In the Central Services instance of an AS ABAP-based SAP system, certain processes can run optionally, complementing the core services provided by the instance. These optional processes include:
* B. RFC Gateway:The RFC (Remote Function Call) Gateway enables communication between SAP systems and between SAP systems and external systems using the RFC protocol. Running the RFC Gateway as part of the Central Services instance can facilitate centralized management of RFC communications, especially in complex landscapes requiring numerous cross-system integrations.
* C. SAP Web Dispatcher:The SAP Web Dispatcher functions as an application-level gateway, load balancer, and reverse proxy for SAP systems. While it's commonly deployed as a standalone component, in some scenarios, it may run as part of the Central Services instance to provide immediate and integrated routingand load balancing capabilities, particularly in smaller or less complex environments.
Incorporating these processes into the Central Services instance can offer administrative and operational conveniences, depending on the specific requirements and architecture of the SAP system landscape.
