A company's finance team is reporting increased cloud costs against the allocated cloud budget. Which of the following is the BEST approach to match…

Chargeback is the best approach to match some of the cloud operating costs with the appropriate

departments. Chargeback is a process where the IT department bills each department for the

amount of cloud resources they use, such as compute, storage, network, or software. Chargeback

can help the company to allocate the cloud costs more accurately and fairly, as well as to encourage

the departments to optimize their cloud consumption and reduce waste. Chargeback can also

provide the company with more visibility and accountability of the cloud usage and spending across

the organization12

Chargeback is different from showback, which is a process where the IT department shows each

department the amount of cloud resources they use, but does not charge them for it. Showback can

also help the company to increase the awareness and transparency of the cloud costs, but it may not

have the same impact on the behavior and efficiency of the departments as chargeback12

Right-sizing and scaling are not approaches to match the cloud costs with the departments, but

rather techniques to adjust the cloud resources to the actual demand and performance of the

applications or services. Right-sizing and scaling can help the company to save money and improve

the cloud utilization, but they do not address the issue of cost allocation or attribution34
