Introduction
Oracle announced general availability of Oracle Database 12c on June 25, 2013.
Oracle Database 12c introduces a new multitenant architecture that makes it easy to deploy and manage database clouds.
Oracle Database 12c provide private and public cloud deployments for the users.

Oracle Database Options
The Pluggable Databases architecture can currently support up to 252 PDBs in a single CDB Database.
You can utilize Database Links between PDBs and between PDBs and non-CDB databases.
Database Link
Container Database (CDB)
Multiple DB Instances
Share servers and OS with
“DB Instance Isolation”
Virtual Machines
Share serverswith
“VM isolation”
NEW DB 12c Multitenant
Share servers, OS and database with
“Pluggable DB Isolation”
Database Cloud & Consolidation Architectures
Customers have 100s or 1000s of databases across their enterprise.
They want to lower costs by operating these databases on a centrally managed platform.
With only hardware consolidation, each database has an overhead, that prevents 100s of database from being placed on the same physical server.
The need for Database ConsolidationWhy…?
