Abstract

This paper explores cost-reduction models and strategies for optimizing billing in AWS environments, particularly focusing on cloud-native applications. The growing adoption of cloud technologies has made cost optimization an essential factor in achieving sustainable and efficient cloud infrastructure. AWS offers a wide array of pricing models and services, but effective cost management requires businesses to understand and apply strategic measures such as right-sizing instances, leveraging Reserved Instances (RIs), and utilizing Savings Plans. Additionally, advanced techniques like auto-scaling, Spot Instances, and serverless computing present substantial opportunities for reducing cloud expenses. The paper also highlights the role of third-party cost management tools and AWS’s native cost monitoring solutions in providing businesses with the insights needed to optimize resource utilization and minimize waste. The findings show that through continuous monitoring and dynamic resource allocation, organizations can optimize costs while maintaining performance. The paper concludes with insights on future directions for cost reduction in AWS environments, including the use of AI-powered optimization tools and multi-cloud management strategies, ensuring that cloud-native applications can scale efficiently without incurring unnecessary expenses.
