Efficient Resource Cloud Formation Using Virtualization in SLA-Based Cloud Technologies

Abstract

Cloud computing has arisen as a viable remedy to the constraints of conventional IT systems, product delivery methodologies, and application management methods, including licensing, configuration, and maintenance.  Transitioning from traditional platforms to cloud-based settings diminishes customer-side complexity and expenses, while guaranteeing continuous income for Software as a Service (SaaS) suppliers.  Service Level Agreements (SLAs) are instituted as enforceable promises between customers and providers to uphold quality of service (QoS).  The main objectives for SaaS providers are to minimize operating expenditures and to maximize Customer Satisfaction Levels (CSL).  The present work presents customer-centric SLA algorithms for effective resource allocation, aimed at cost reduction through the minimization of support overheads, fines, and SLA breaches. The suggested system amalgamates user profiles and supplier performance data to encapsulate intricate client needs and tackle heterogeneity across business networks. Customer-specific factors, like enhancement request rates and infrastructure-level metrics such as job initiation timings, are integrated for precise decision-making. Simulation outcomes indicate substantial enhancements, with a 54% reduction in total costs and a 45% drop in SLA breaches, surpassing traditional optimization methods.
