Which two OCI database services allow for dynamic scaling of CPU and storage?

The Oracle Autonomous Database (ADW - Autonomous Data Warehouse) and Oracle Autonomous Transaction Processing (ATP) are designed to provide dynamic scaling of both CPU and storage. This capability allows these databases to automatically adjust resources based on workload requirements, ensuring optimal performance without the need for manual intervention. This is a key feature of Oracle's cloud offerings, enabling seamless scalability to handle fluctuating demands efficiently.

In contrast, while Bare Metal DB systems and VM DB systems are also powerful database services, they do not inherently offer the same level of dynamic scaling capabilities as ADW and ATP. Instead, these services typically require more management and manual adjustments for scaling resources, making them less flexible in handling varying workloads automatically.

By focusing on the autonomy of ADW and ATP, which include features like auto-scaling, patching, and tuning, organizations can benefit from a fully managed experience that optimizes both operational efficiency and cost-effectiveness.
