An organization notices that some of their cloud expenditures are too (Digital Leader)

Correct answer: B) Share cost views with the departments to establish more accountability.
Here's why:

A) Streamlining the hardware procurement process may help reduce costs in on-premises environments, but it's not directly related to controlling costs in the cloud. Cloud cost optimization requires strategies specific to cloud services and resource usage.

B) Sharing cost views with departments fosters transparency and accountability regarding cloud expenditures. By providing departments with visibility into their respective usage and costs, they can better understand the impact of their actions on overall expenses and make informed decisions to optimize resource utilization and reduce unnecessary spending.

C) Changing the cost model from operational expenditure to capital expenditure may provide financial benefits in certain cases, but it does not directly address the issue of high cloud expenditures. Moreover, such a change may have broader financial and accounting implications that need careful consideration.

D) Ensuring that all cloud resources are tagged with a single tag is important for cost allocation and tracking, but it's just one aspect of cost management. While tagging helps identify the owner or purpose of resources, it does not inherently control costs. Implementing effective tagging practices is a prerequisite for cost management but should be accompanied by other cost optimization strategies.

Therefore, B) Share cost views with the departments to establish more accountability is the most appropriate action for the organization to control costs effectively by fostering transparency, accountability, and informed decision-making across departments.
