Abstract

The performance of a computing cloud depends on its agile response to the user needs and in the quality of the service provided. SLA assurance will increase user's confidence in the system by guaranteeing the cloud resources needed to users at certain point in the future. Negotiation between the cloud provider and consumer is necessary to achieve SLA. Haizea is an open source lease manager which can act as a scheduler for OpenNebula. It uses resource leases as resource allocation abstraction and executes these leases by allocating virtual machines. Haizea does not support negotiation currently. This work implements negotiation process using Haizea to provide SLA based lease admission. The experiment results show that the proposed method increases system utilization and maximizes the number of leases accepted as compared to Haizea's default policies.
