A cloud resource orchestration framework for simplifying the management of web applications

Abstract

Cloud computing paradigm [1] has shifted the computing from physical hardware- and locally managed software-enabled platforms to virtualized cloud-hosted services. Cloud computing assembles large networks of virtualized services: hardware resources (CPU, storage, and network) and software resources (e.g., databases, load-balancers, monitoring systems, etc.). Key issue in exploiting the potential of cloud computing is "Resource Orchestration". Resource orchestration process spans across a range of operations from selection, assembly, and deployment of resources to monitoring their run-time performance statistics (e.g. load, availability, throughput, utilization, etc.). The process aims to ensure achievement of fault-tolerant and QoS fulfillment states by resources and applications through adaptive management. © 2012 Springer-Verlag.
