Future large scale systems, such as cloud datacenters, with increased core counts will soon result in infrastructures with millions of cores. This poses challenges for monitoring and management not yet met by existing experimental or commercial software systems. At the core of this challenge is to perform continuous and on-demand monitoring queries over distributed aggregated data resulting fro...

We introduce the notion of a Personal Cloud — a collection of Virtual Machines (VMs) running on unused computers at the edge. The Personal Cloud provides an ideal solution for the secure sharing of compute and storage resources across peers in a resource and application agnostic manner, and facilitates new computational paradigms such as datacenter-less, distributed virtual clouds. We provide a...

The emerging ecosystem of cloud applications leads to significant inter-tenant communication across a datacenter’s internal network. This poses new challenges for cloud network sharing. Richer inter-tenant traffic patterns make it hard to offer minimum bandwidth guarantees to tenants. Further, for communication between economically distinct entities, it is not clear whose payment should dictate...

Cloud and IoT applications employ a wide range of advanced hardware and software techniques. This paper focuses on utilization of network bandwidth, and proposes the concept of "Bandwidth as a Service" (BaaS) between devices in cloud and IoT environments. Conventional controls for bandwidth are discussed, and a novel algorithm is proposed for dynamically shaping bandwidth into percentage groups...

Datacenters are at the heart of AI, Industry 4.0 and cloud revolution. A datacenter contains a large number computing nodes hosted in temperature-controlled room. Due to increasing total power density nodes, overall compute capacity is often capped by peak consumption temperature bottlenecks. To preserve homogeneous performance assumption between all complex cooling solution required, but they ...

The typical interaction between cloud provider and customer works as follows: the customer connects to a “cloud marketplace” through a Web interface, and selects the type and amount of the resources she needs (e.g., some virtual servers with given number of CPU cores, memory and disk space). The resources are allocated from a large pool that is physically hosted on some big datacenter managed b...

With the large-scale grid connection of renewable energy sources, frequency stability problem power system has become increasingly prominent. At same time, development cloud computing and its applications attracted people’s attention to high consumption characteristics datacenters. Therefore, it was proposed use flexibility datacenters respond demand response signal smart maintain system. Speci...

Introduction The evolutionary change of telecommunications networks towards all-IP mechanisms has begun to collapse the traditional boundaries between IT infrastructure and telecommunications infrastructure. The IT datacenter has for years been the location for web-based services and applications. As the telecommunications environment has moved to all-IP, more and more of the functions of the n...

Iaan latest years, the concept of interconnecting clouds to allow common service coordination gained significant attention mainly because of the increasing utilization of cloud resources from Internet users. An efficient common management between different clouds is essential benefit, like boundless elasticity and scalability. Yet, issues related with different standards led to interoperability...

Abstract. Mobile cloud computing has emerged aiming at assisting mobile devices in processing computationally or data intensive tasks using cloud resources. This paper presents an optimization approach for utilizing cloud services for mobile client inmobile cloud, which considers the benefit of both mobile device users and cloud datacenters. Themobile cloud service provisioning optimization is ...
