Database-as-a-Service (DBaaS) is a cloud database, a database that typically runs on a cloud platform, where access to the database is provided as a service. Database services offer scalability and high availability of your database. Using a database as a service model, application owners do not have to install and maintain the database themselves. The provider of the database services does this.
DBaaS and Cegal
Cegal has excellent experience of DBaaS (although the term itself is a little outdated). "DBaaS" is now more associated with Autonomous/Self-Driving databases.
In Oracle Public Cloud, Oracle provides the following services for databases:
Virtual Machine for Oracle databases
Bare Metal for Oracle databases
Exadata Cloud Service
The first three are ‘Customer-managed’ database services, where Oracle is responsible for the infrastructure at the bottom, and the customer itself is responsible for the ‘VM's’ on which the services run.
Number 4 – Autonomous databases incorporate some machine learning and functionality which makes the database more or less autonomous, without the customer having to do anything other than increase/decrease the need for resources.
Cegal possesses considerable expertise relating to Oracle Cloud and can assist in finding the right solution based on need and price.
