SAP S/4 HANA provides various deployment models such as On Premise, Cloud and Hybrid solution. When you deploy S/4 HANA system in the cloud deployment scenario, data replication is performed using the same mechanisms that is used in on-premise installations - SLT. To perform data replication via SLT, SLT portions will have to be available on both the sending (On-premise) and the receiving system (Cloud).
Non-SAP reporting and analytics and additional SAP Simple Finance or partner products need to be connected to the cloud instance or be made available within the cloud installation as required.
In On-premise deployment model, the customer purchases software and hardware; the operations are managed by the customer itself. All the deployment, implementation and maintenance tasks are performed by the customer. Any new software extensions are handled by on-premise support team.
In this deployment, hardware and software is provided by the cloud solution provider and it is rented to the customer. The cloud service provider is responsible for performing all the updates, extensions, and new implementations.
In this deployment scenario, some part of the software is run by the client on-premise server owned by the client, and additional solution is provided by the client provider. You need to perform an integration between on-premise and cloud environment for better service.
You can have different user types in S/4 HANA system to meet the business requirement. In every company, you have three basic user types −
Occasional − These user types occasionally use the system and need simple and easy-to-use applications.
Expert − This user type is a fully trained SAP user who knows the system effectively and uses multiple systems and different UIs.
Developer − These users are responsible for adaption and extension of existing applications. These users have to access several applications with different user interfaces.
