Managing Oracle Database 12c with Enterprise Manager – Part X - Database as a Service

We are discussing the management of Oracle Database 12c in Oracle Enterprise Manager 12c. In our previous blog post on this topic, we looked at the Database Resource Manager and how it can be used to control resources at the PDB level in Database 12c.
Let us now look at how Enterprise Manager’s “Database as a Service (DBaaS)” capability works with Database 12c and its container and pluggable databases.
With Oracle Enterprise Manager 12c, the Cloud Administrator is able to set up and offer the self-service of virtual machines (Oracle VM) with databases – this being more of an infrastructure cloud or Infrastructure-as-a-service (IaaS), since virtual machines are being provisioned on the fly.
The Cloud Administrator is also able to set up and offer the self-service creation of single-instance or RAC databases on existing Oracle Homes in what is known as a database pool for databases, or alternatively the self-service creation of schemas in an existing single-instance or RAC database in what is known as a database pool for schemas.
This self-service capability can also be called “Database as a Service” and “Schema-as-a-Service” respectively.
With the addition of Database 12c, the additional capability shown in the illustration above is the self-service creation of PDBs, in an existing single instance or RAC Container database (CDB). This is what we now call a database pool for PDBs. This self-service capability can be called as “Pluggable database (PDB) as a Service (PDBaaS)”.
Using this capability, the Cloud Self-Service Access (SSA) users are now able to self-service the provisioning of Pluggable databases inside a Container database very easily. This is the next stage of the Private Database Cloud.
For licensing aspects, as far as DBaaS is concerned, the Cloud Management Pack for Oracle database is required, with the pre-requisite of the Database Lifecycle Management (DBLM) pack – this is the pack that does all of the provisioning under the hood, whereas the Cloud Management pack adds the capabilities of self-service, quotas, chargeback/showback and so on.
