Question 6: Service Instance
Which class sits between the actual server infrastructure and the business service, representing individual environments such as “Production” or “Development”?
- A：Business Capability
- B：Application Service
- C：Information Object
- D：Technical Service
【Correct Answer】 B. Application Service
【Detailed Explanation】
Why B is the correct answer (Application Service):
In CSDM 5.0, the Application Service acts as the hub (connecting point) that bridges “logical design” (Business Application) and “physical infrastructure” (Servers/Databases).
- Role: It represents an “instance” deployed for a specific purpose.
- Example: It is created for each individual environment, such as “SAP ERP – Production,” “SAP ERP – Development,” or “SAP ERP – DR (Disaster Recovery).”
- Phase: It is a primary CI (Configuration Item) in the BUILD & RUN phase located in the center of the CSDM diagram.
Why the other options are incorrect:
- A (Business Capability): This belongs to the IDEATION & STRATEGY phase. It is a top-level concept defining “what the business can do” (e.g., “Ability to process payroll”) and is not directly related to technical environments like servers.
- C (Information Object): This belongs to the DESIGN phase. It is a logical element that defines the “types of data” the application handles (e.g., customer information, HR data).
- D (Technical Service): This belongs to the BUILD & RUN phase, but it represents the “technical expertise” provided by IT operations teams (e.g., Windows Server Management, Network Maintenance). It does not refer to the specific system environment (Production/Development) itself.
