SLA-Aware Adaptive Provisioning Method for Virtualized Application Execution Environments

摘要

Resource provisioning is a general technique for handling the resource allocation in cloud environment. Monitoring the system performance and the user request is crucial for efficient cloud resource management. Also in cloud environments, issues such as cost and resource provisioning based on QoS constraints are yet to be addressed. In this paper, we present a SLA(Service Level Agreement) - Aware Adaptive (SAA) provisioning method for Virtualized Applications that employ a flexible determining model. We present advanced cloud infrastructure which maintain proper virtual machine numbers by optimizing resources allocation. Our experiments show that our adaptive model minimize the maintain cost of virtual machines while satisfying user average response time constraint and the request arrival rate constraint.
