Abstract:

This study examines the differences between cloud-based and on-premises applications, specifically focusing on an airline website. The investigation uses descriptive statistics from survey responses to analyze performance, cost-effectiveness, scalability, and security aspects. The study assesses user satisfaction with cloud-based and on-premises applications in terms of response time, availability, stability, peak traffic handling, and overall performance. Statistical analysis shows that cloud-based applications typically outperform on-premises solutions in these metrics, with mean scores indicating satisfactory performance. An evaluation of licensing fees, pricing structures for updates and upgrades, ongoing maintenance costs, hosting expenses, and overall cost-effectiveness shows that cloud-based applications are generally considered more reasonable, transparent, and cost-efficient than on-premises alternatives.The research examines the scalability and adaptability of both types of applications in response to evolving system requirements and technological advancements. Cloud-based applications are becoming more scalable and adaptable, enabling dynamic adjustments to fluctuating workloads, while on-premises solutions struggle to keep up with new technologies. The study investigates user opinions on data security, access control, encryption methods, regulatory compliance, backup and disaster recovery, and physical security protocols. On-premises applications are considered to provide enhanced data security and improved control over access management, whereas cloud-based applications are known for their strong encryption methods and dependable backup and disaster recovery capabilities. Dyadic samples T-tests show a statistically significant disparity in user satisfaction regarding performance and costs between cloud-based and on-premises applications. Cloud-based applications show superior performance scores on average, whereas on-premises applications have slightly higher average scores for costs. Regression analysis confirms the correlation between performance and costs, highlighting the beneficial influence of cloud-based performance on cost-efficiency. The findings provide important insights for the current discussion on application selection, highlighting the importance of performance, cost-effectiveness, scalability, and security factors.
