Queries Based Workload Management System for the Cloud Environment

Workload management for concurrent queries is one of the challenging aspects of executing queries over the cloud computing environment. The core problem is to manage any unpredictable load imbalance with respect to varying resource capabilities and performances. Key challenges raised by this problem are how to increase control over the running resources to improve the overall performance and response time of the query execution. This paper proposes an efficient workload management system for controlling the queries execution over cloud environment. The paper presents an architecture to improve the query response time by detecting any load imbalance over the resources. Also, responding to the queries dynamically by rebalancing the query executions across the resources. The results show that applying this Workload Management System improves the query response time by 68%.
