Service level agreements are like a roof that encompasses our entire portfolio. They are a way for our customers to ensure they receive the best possible service. The guaranteed availability of staff and short response times can all be taken into account. These agreements reduce the risk of the customer`s operation to a computable factor by defining individual procurement services and emergency services provided. A large number of KPIs (Key Performance Indicators) can be integrated into a service level contract. We offer a capacity-based utilization model to support cloud services trading. Dynamic customer requirements and the availability of vendor resources in the cloud market make them insufficient static approaches to ensure the QoS level (quality of service) and set prices. In this context, dynamic information negotiations are a viable way to achieve a high level of satisfaction on both sides. We propose to use capacity planning to support bilateral negotiation processes, in order to maximize benefits for service providers by avoiding contracts that could arise in the event of a breach of Service Level Agreements (SLAs), while maintaining competitive prices. The proposed technique uses a non-additive use function defined in the area of acceptable ALS proposals, taking into account the desired QoS and the availability of resources, costs and expected penalties. Experimental analysis shows the usefulness of the proposed dynamic approach in terms of static In a scenario characterized by a set of customers and differentiated classes of applications provided by a cloud environment.
Although the service level agreement is tailored to each customer, there are a number of areas that are fairly standardized. The utility function takes into account available resources dynamically. The approach improves the supplier`s utility and reduces ALS injuries. Eugenio Zimeo graduated in 1999 with an M.S. degree in Electrical Engineering from the University of Salerno, Italy, and in 1999, a doctorate in computer science from the University of Naples, Italy. He is currently an Associate Professor at the University of Sannio, Benevento, Italy. His research priorities include software architectures and frameworks for distributed systems, high-performance middleware, service-oriented computing, grid and cloud, and wireless sensor networks. He has published approximately 90 scientific papers in journals and specialized conferences and directs many major research projects. Our Standard-Service Level Agreement is available on request. Both individuals and organizations working with arXivLabs have accepted and accepted our values of openness, community, excellence and user data protection. arXiv is committed to these values and only works with partners who comply with them. arXivLabs is a framework that allows employees to develop and share new arXiv functions directly on our website.
