Which of the following is NOT a recommended service for managing a project with Oracle E-Business Suite on OCI?

The selection of OCI Streaming Service as the choice that is not recommended for managing a project with Oracle E-Business Suite on OCI is correct because it is not primarily designed for the types of operations needed by E-Business Suite. The Oracle E-Business Suite functions require services that are focused on database management, compute resources, and file storage, which directly support the application's infrastructure, performance, and data handling needs.

OCI Virtual or Bare Metal DB Systems, Virtual Machine or Bare Metal compute instances, and File Storage Service are all essential components in supporting E-Business Suite. These services provide necessary environments for hosting databases, running applications, and storing files, which are crucial for seamless operation.

In contrast, the OCI Streaming Service is tailored toward processing data streams and real-time analytics and is not specifically aligned with the core functionalities or operational requirements of Oracle E-Business Suite applications. Therefore, while it may be beneficial in other contexts, it does not fit the core infrastructure needs for E-Business Suite management.
