Resource provisioning in Science Clouds: Requirements and challenges
Cloud computing has permeated into the IT industry in the last few years, and it is nowadays emerging in scientific environments. Science user communities are demanding a broad range of computing power to satisfy high-performance applications needs, such as local clusters, High Performance Computing (HPC) systems and computing grids. Different workloads need from different computational models,...
متن کاملProvisioning, Resource Allocation, and DVFS in Green Clouds
The aim of Green Cloud Computing is to achieve a balance between resource consumption and quality of service. In order to achieve this objective and to maintain the flexibility of the Cloud, dynamic provisioning and allocation strategies are needed to manage the internal settings of the Cloud, addressing oscillatory peaks of workload. In this context, we propose strategies to optimize the use o...
متن کاملResource Provisioning of Web Applications in Heterogeneous Clouds
Cloud computing platforms provide very little guarantees regarding the performance of seemingly identical virtual machine instances. Such instances have been shown to exhibit significantly different performance from each other. This heterogeneity creates two challenges when hosting multi-tier Web applications in the Cloud. First, different machine instances have different processing capacity so...
متن کاملCost-Aware On-Demand Resource Provisioning in Clouds
Cloud computing has been gaining increased popularity among companies for a couple of years. Low upfront costs and the enormous elasticity make it an attractive alternative to in-house IT solutions. However, most companies still tend to overprovision their IT infrastructures induced by the buffering behavior to avoid violations of service level agreements. The introduction of dynamic scaling in...
متن کاملResource Provisioning for e-Science Environments
Recent works have proposed a number of models and tools to address the growing needs and expectations in the field of e-Science. At the same time, the availability and models of use of networked computing resources needed by e-Science are rapidly changing and see the coexistence of many disparate paradigms: high performance computing, grid and recently cloud, which brings very promising expecta...
