Modeling and simulation of global and sleep states in ACPI‐compliant energy‐efficient cloud environments.
The more large‐scale data centers infrastructure costs increase, the more simulation‐based evaluations are needed to understand better the trade‐off between energy and performance and support the development of new energy‐aware resource allocation policies. Specifically, in the cloud computing field, various simulators are able to predict and measure the behavior of applications on different architectures using…
Mobile application testing on Clouds: challenges, opportunities and architectural elements
With mobility increasing more each year, mobile devices and operating system (OS) fragmentation are increasing at an even faster pace. A multitude of screen sizes, network connection types, and OS versions have emerged in the market and led mobile developers to rethink testing practices to ensure quality and a good experience for increasingly demanding users…
Optimizing multi‐tier application performance with interference and affinity‐aware placement algorithms
Cloud providers are constantly seeking to become more cost effective, where a common strategy is to consolidate multiple applications in physical machines using virtualization techniques. This consolidation, however, may result in performance related problems such as resource interference. Moreover, if the workload is composed of multi‐tier applications, an increasingly popular method of application development, especially…
Modeling and Simulation of QoS-AwarePower Budgeting in Cloud Data Centers
Cloud computing has transformed the means of computing in recent years with several benefits over traditional systems, like scalability and high availability. However, there are still some opportunities, especially in the area of resource provisioning and scaling . Since workload may fluctuate a lot in certain environments, over-provisioning is a common practice to avoid abrupt…
Understanding and Minimizing Disk Contention Effects for Data-Intensive Processing in Virtualized Systems
Power budgeting is a commonly employed solution to reduce the negative consequences of high power consumption of large scale data centers. While various power budgeting techniques and algorithms have been proposed at different levels of data center infrastructures to optimize the power allocation to servers and hosted applications, testing them has been challenging with no…
