Description: Cost Quantitative Analysis in the context of FinOps and cloud cost optimization refers to the systematic and numerical evaluation of expenses associated with the use of cloud services. This approach employs statistical and mathematical methods to identify consumption patterns, assess resource efficiency, and detect savings opportunities. As organizations increasingly adopt cloud solutions, cost control becomes a critical priority. Quantitative analysis enables companies not only to understand their current expenses but also to project future costs and establish more accurate budgets. Key features of this analysis include data collection on resource usage, cost segmentation by department or project, and expense comparison with industry benchmarks. The relevance of this approach lies in its ability to transform complex data into clear and actionable information, facilitating informed decision-making that can lead to more efficient resource management in cloud environments. In an environment where costs can escalate rapidly, Cost Quantitative Analysis becomes an essential tool for organizations seeking to maximize their return on investment in cloud technology.
