| description | The use of Grid and Cloud Computing for resource sharing has received tremendous
attention in recent years. The merging of virtualization, utility computing and distributed
computing with Service Oriented Architecture (SOA) has provided greater flexibility and
ushered in a new paradigm of on-demand services. However, job scheduling remains a
formidable challenge due to the dynamic and heterogeneous nature of Grid and Cloud
Computing. Furthermore, the increasing and diverse end users requests raise new and
greater urgencies to resolve the provisioning of Quality of Service (QoS).
This thesis proposes a Hybrid Scheduling Algorithm (HSA) with automatic deployment
mechanism that maximizes resources utilization and minimizes total makespan.
Subsequently, an Adaptive Scheduling Algorithm (ASA) that uses benchmarking is
proposed to enhance the HSA. ASA is able to optimize the job scheduling performance
over other approaches. Finally, Adaptive QoS Scheduling Algorithm (AQoSSA), an
enhancement of ASA, is presented to meet the varied users QoS requirements. AQoSSA is
able to maximize reliability and profit while guaranteeing the users’ QoS requirements.
An experimental testbed is developed to evaluate the performances of all the proposed
algorithms. The makespan results showed that the HSA and ASA outperformed the
conventional MIN-MIN and MAX-MIN by between 1% - 10% and 5% - 17% respectively.
Whereas, AQoSSA outperformed MIN-MIN QoS and MAX-MIN QoS by between 3% -
6% and 10% - 47% in terms of reliability and profit respectively while guaranteeing the
users’ QoS requirements. |
