This image shows an extended architecture typical of SaaS extensions based on Oracle Java Cloud Service - SaaS Extension. Three separate environments, one for Production, one for Test, and one labeled Developer 1 are shown. In each environment, components are labeled with environment-specific names, such as WXYZ (for Production), WXYZ-Test (for Test), and WXYZ-Dev1 (for Developer 1).

Each environment has the same arrangement of components: Oracle Applications, for example HCM, Sales Cloud, and ERP, interact with a Traditional Account. Oracle Java Cloud Service - SaaS Extension connects to the Traditional Account, and to an Oracle database schema. Oracle Applications and Oracle Java Cloud Service - SaaS Extensionare also directly connected.
