Oracle Database Cloud Service (DBCS) provides you the ability to deploy Oracle databases in the Oracle Cloud. Each database deployment contains a single Oracle database in a Virtual machine image. You can’t create multiple databases in one database deployment if you want to create multiple databases then you create a 12c Container database with multiple Pluggable databases. Oracle DBCS or also known as DBaaS is part of Platform as a Service (PaaS) offering. The compute, virtual machine, storage, network, optionally tools to simplify routine database maintenance and management operations are provided by Oracle. You will have full access to the features and options available with Oracle Databases.

When you create a database deployment, Database Cloud Service creates compute nodes to host the database, using computing, storage and networking resources provided by various Oracle Cloud infrastructure services.

Oracle Database Type

Database Type
Description
Single Instance
A single Oracle Database instance and database data store hosted on one compute node.
Database Clustering with RAC
A two-node clustered database using Oracle Real Application Clusters technology; two compute nodes each host an Oracle Database instance, and the two instances access the same shared database data store.
Single Instance with Data Guard Standby
Two single-instance databases, one acting as the primary database and one acting as the standby database in an Oracle Data Guard configuration.
Database Clustering with RAC and Data Guard Standby
Two two-node Oracle RAC databases, one acting as the primary database and one acting as the standby database in an Oracle Data Guard configuration.
Data Guard Standby for Hybrid DR
Single-instance database acting as the standby database in an Oracle Data Guard configuration. The primary database is on your own system.

Automatic Backup Configuration

When you create a new database deployment on DBCS, you can choose whether you want to configure automatic backup for your database.

Backup Option
Description
Both Cloud Storage and Local Storage
30 days worth of backups are kept, with the 7 days most recent backups available directly on the compute node’s local storage.
Cloud Storage Only
30 days worth of backups are kept, with all backups on cloud storage.
