Decoupling the lifecycle of the UI apps from the backend, especially for the apps that must also run on anyDB.
a. Allow faster iterations for the UI apps
b. Allow changes to UI by LOB without the need for development privileges in the backend
c. Single point of UI maintenance issues like browser support & versions or UI5 provisioning
Central place for theming and branding
Single place for configuration, personalization, and Fiori shell services
Rules based dispatching of request in a multi system landscape like for approvals or timesheets
Security considerations:
a. Similar to an ALG with protocol switch, whitelisting
b. Admin for UI meta data does not need to have admin rights in backend (Data Sensitivity)
