Recent research in pricing models for cloud computing services focuses on developing adaptive and market-oriented strategies that optimize resource utilization, cost efficiency, and provider profitability. These models incorporate dynamic pricing, auction-based mechanisms, and demand forecasting to adjust prices in real time based on workload fluctuations and user requirements. Game-theoretic and economic approaches are often employed to balance competition among providers and fairness for consumers. By integrating factors such as energy consumption, service-level agreements, and user preferences, modern pricing models aim to achieve sustainable and transparent cost structures while enhancing the overall efficiency and scalability of cloud service delivery.
