You can unplug a PDB from a development CDB and plug it into a production CDB, which allows for easier and more rapid movement of data and code.

You can consolidate shared database memory by combining multiple PDBs in a single CDB.

Patching individual PDBs requires the same amount of time as patching individual databases.

Consolidating separate databases into a single CDB requires the same amount of storage allocation.

In multitenant architecture, a PDB behaves the same as a non-CDB as seen from a client connecting with Oracle Net. No client modification is required.
