What is Resource Replication

Chapter 5
Handbook of Research on Machine Learning Innovations and Trends
The creation of multiple instances of the same resource, it enables data from one resource to be replicated to one or more resources. That is typically performed when a resource’s availability and performance need to be enhanced. AU57: Pict Element 1

Abstract
Workload Management is a performance management process in which an autonomic database management system on a cloud environment efficiently makes use of its virtual resources. Workload management for concurrent queries is one of the challenging aspects of executing queries over the cloud. The core problem is to manage any unpredictable overload with respect to varying resource capabilities and performances. This chapter proposes an efficient workload management system for controlling the queries execution over a cloud. The chapter presents architecture to improve the query response time. It handles the user's queries then selecting the suitable resources for executing these queries. Furthermore, managing the life cycle of virtual resources through responding to any load that occurs on the resources. This is done by dynamically rebalancing the queries distribution load across the resources in the cloud. The results show that applying this Workload Management System improves the query response time by 68%.
