Present-era is relying on high technology mobile, broadband and wireless technologies. These technologies accomplish their tasks with the help of cloud computing services. Cloud computing technology provides the storage, infrastructure and software “as service”, allow users to access services with flexible and economical way through internet. In this paper cloud resource management and QoS (quality of service) has discussed. We used cloud simulator cloud Sim to simulate our collaborative layered approach for resource allocation and management. This collaborative layered approach consists of Virtual machine allocation (VM Allocation) policy, virtual machine scheduler (VM Scheduler) and virtual machine migration (VM Migration) controller. Enhanced VM Allocation policy provides hosts based on load balancing and aging constraints. VM Scheduler provides best time shared scheduling to allocate resources to virtual machine to particular host. Virtual machine controller uses fuzzy logic to control the migration of virtual machines. We analyses the service providing time and success rate of our collaborative layered approach in different scenarios to ensure the QOS. This approach provide better resource management for cloud service providers(CSP) as it reduces the response time and enhanced service availability. © Research India Publications.
