Private Cloud Database and Pluggable Database
This chapter discusses the structures of a private cloud and Pluggable database (PDB). The usage of databases has increased over the past years, and dozens of databases are used in data centers to store this data. However, the complexity in the management of these systems normally increases as the data increases, and consolidation of these data under one roof is required. Older silo solutions no longer support these data sizes. In fact, a lot of time is spent and resources are used due to separate systems in a data center because many databases are managed at different servers and a database administrator and technical person must be assigned to every machine; in other words, a new resource must be provided for every database. Oracle 12c was released as a PDB to host one or more databases from only one database server through a container database.
