A performance model for scalable cloud computing

چکیده
Cloud computing is a new paradigm that offers several advantages in terms of scalability, maintainability, high availability, efficiency and data processing. Infrastructure and applications are moved to the cloud and provided as a pay-for-use service. When designing a cloud infrastructure, it is critical to assure beforehand that the system will be able to offer the desired level of QoS (Quality of Service). Our attention is focused here on simulation environments for cloud computing systems. This paper presents a model based on queuing theory for service performance in cloud computing. More complicated cloud-based proposals are then presented. Such models, based on event-driven simulation, possess scheduling capabilities for heterogeneous and non-dedicated clouds. The results demonstrate the usefulness of the simulation models presented for the design of cloud computing systems with guarantees of QoS under ideal conditions and when scaling the system.

Cloud computing is considered to be a new service provider technology for users and businesses. However, the cloud environment is facing a number of challenges. Resource allocation in a way that is optimum for users and cloud providers is difficult because of lack of data sharing between them. On the other hand, job scheduling is a basic issue and at the same time a big challenge in reaching hi...
