OCI Block Volumes is the service used by default by the MySQL Database Service to store user data to make it more resistant to failures. OCI Block Volumes provides high-performance block storage volumes that can be attached to MySQL DB systems running on OCI Compute instances. Block volumes are always encrypted at rest using AES-256 encryption keys. Block volumes also support backup and restore operations using snapshots or clones that can be used for disaster recovery or testing purposes.

This statement is true about how the Converged Database helps to access data using an API. According to the Oracle documentation5, “Oracle REST Data Services (ORDS) makes it easy to develop modern REST interfaces for relational data in the Oracle Database and the Oracle Database 18c JSON Document Store. A mid-tier Java application, ORDS maps HTTP(S) verbs (GET, POST, PUT, DELETE, etc.) to database transactions and returns any results formatted using JSON.” ORDS can automatically generate RESTful services for tables and views in the database or expose custom REST APIs using SQL or PL/SQL.

The goal of scale out high availability can be achieved by provisioning nodes with Real Application Clusters (RAC). According to the Oracle documentation6, “Oracle Real Application Clusters (RAC) enables you to scale out your database by adding nodes as needed without changing your application code. RAC also provides high availability by automatically recovering from node failures.” RAC allows multiple instances of Oracle Database to run on different servers while accessing a shared set of data files.
