When scaling resources in ATP, which two components can be scaled independently?

When considering the scaling of resources in Autonomous Transaction Processing (ATP) within Oracle Cloud Infrastructure (OCI), the correct response focuses on the independent scalability of CPU and Storage.

CPU can be adjusted based on the computational requirements of your workload, allowing you to increase or decrease processing power without impacting other components. This is particularly useful during variable workload demands where high-performance processing is required for short periods.

Storage, on the other hand, can also be scaled independently to accommodate changes in data volume without the requirement to resize or reconfigure the CPU. You might find that your application data grows faster than expected, necessitating an increase in storage capacity while your CPU requirements remain steady.

The ability to scale these components independently ensures that you can optimize both performance and cost, as resources can be adjusted in response to actual usage rather than needing to scale up or down as a single unit.

In contrast, other combinations mentioned, such as CPU with Diskgroup, or Storage with Diskgroup, do not accurately reflect the independent scalability afforded by the architecture of ATP. Diskgroups are associated with storage management rather than acting as a separate and independently scalable resource in the same manner as CPU and Storage.
