ABAP Netweaver, SAP Cloud Platform和Kubernetes的用戶區分

ABAP

• Dialog: Individual, interactive system access.
• System: Background processing and communication within a system (such as RFC users for ALE, Workflow, TMS, and CUA).
• Communication:Dialog-free communication for external RFC calls.
• Service: Dialog user available to a larger, anonymous group of users.
• Reference: General, non-person related users that allows the assignment of additional identical authorizations, such as for Internet users created with transaction SU01. No logon is possible.

Business user vs technical user：

Kubernetes

也有User Account和Service account的概念。

用戶賬戶爲用戶提供帳戶標識，而服務帳戶爲計算機進程和Kubernetes集羣中運行的

Pod提供帳戶標識。二者的一個區別是做用範圍：前者對應人的身份，與服務的namespace無關，所以用戶帳戶是跨namespace的；然後者對應的是一個運行中程序的身份，所以與特定namespace相關。
