Large cloud-computing datacenters now host a wide range of business applications, ranging from e-commerce websites to search engines to data mining. Increasingly, these datacenters use renewable energy from wind turbines or solar panels to reduce their dependence on costly and less clean energy from the grid [17, 4, 1]. This paper argues that datacenter management should be revised to maximize ...

Over the past decade, datacenters and their networks have become technology enablers for a number of internetbased applications. As of today, most of the popular internet applications, from the traditional search, online interactive maps, social networks, video streaming, and the Internet of Things, are running in datacenters. The pivotal role played by the datacenter will be further heightened...

Virtualization is the ubiquitous way to provide computation and storage services to datacenter end-users. Guaranteeing sufficient data storage and efficient data access is central to all datacenter operations, yet little is known of the effects of virtualization on storage workloads. In this study, we collect and analyze field data from production datacenters that operate within the private clo...

Data Centers have become the digital backbone of the modern society with the advent of cloud computing, social networking, Big data analytics etc. They play a vital role in processing the large amount of information generated. The number of Data Centers and the servers present in them has been on the rise over the last decade which has eventually led to the increase in the power consumption of ...

We are developing an advanced IaaS (Infrastructure-as-a-Service) datacenter management system that dynamically minimizes running physical servers depending on resource utilization. The management system periodically monitors the loading of a datacenter, and dynamically repacks virtual machines (VMs) into optimal physical servers. Live migration of VMs and the standby mode of physical servers ar...

Distributed Cloud Computing Network is an important subsystem in an on going research referred to as Smart Green Energy Management System (SGEMS). In this paper, we propose a dynamic service availability architecture using two server types (virtualized and legacy server types) and their QoS metrics (particularly service delay time and resource availability) for detailed analysis. The work is ai...

The recent growth in demand for modern applications combined with the shift to the Cloud computing paradigm have led to the establishment of large-scale cloud data centers. The increasing size of these infrastructures represents a major challenge in terms of monitoring and management of the system resources. Available solutions typically consider every Virtual Machine (VM) as a black box each w...

The rapid growth of cloud computing, both in terms of the spectrum and volume of cloud workloads, necessitate re-visiting the traditional rack-mountable servers based datacenter design. Next generation datacenters need to offer enhanced support for: (i) fast changing system configuration requirements due to workload constraints, (ii) timely adoption of emerging hardware technologies, and (iii) ...
