Which of the following is NOT a focus area of Oracle Cloud Cost Management?

The focus areas of Oracle Cloud Cost Management are designed to help organizations manage and optimize their cloud expenditures effectively. An essential aspect of this management includes cost visibility, which allows users to see and analyze their cloud spending in real-time. Resource optimization is another pillar, emphasizing the efficient use of resources to avoid unnecessary expenses. Budget adherence focuses on ensuring that expenditures stay within the predetermined financial limits, aiding in financial planning and accountability.

Operating system updates, while important for overall system maintenance and security, do not fall under the direct umbrella of cost management in the cloud context. The primary concern within Oracle Cloud Cost Management is not about managing operating systems but rather about overseeing cloud costs and resources. Thus, this makes it clear why operating system updates are not a focus area for Oracle Cloud Cost Management.
