Download or read book Towards Application centric Fairness in Multi tenant Clouds with Adaptive Cpu Sharing written by Anthony Ojo Ayodele and published by . This book was released on 2016 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing rush for cloud-based services by small, medium, and large-scale organizations in other to reduce operational cost overhead, and have more flexibility in the deployment of business applications continues unabated. Cloud computing environment allows sharing of configurable computing resources (e.g., CPU, memory, networks, servers, storage, applications, and services) among cloud tenants. Thus, the cloud computing environments has significantly simplified the capacity provisioning process to support massive migration of enterprise applications to the cloud. However, there exist several challenges facing cloud services that are preventing cloud subscribers; individuals, private, and public organizations from achieving total satisfaction. These challenges include CPU sharing, contention for hardware, and lack of fairness in re source management. This dissertation aims at supporting ongoing research efforts in academia and private industry in addressing these challenges. The contributions of this dissertation start with measurement and interference profiling of application performance i n multi-tenant cloud environment. Through series of quantitative and qualitative experimental research methods in public and private clouds, this dissertation reveals how an imbalance in the allocation of shared cloud computing resources affect in-cloud application performance. The dissertation examined the complex interplay among cloud tenants as they compete for CPU time, and shared hardware resources by identifying the relationship between low-level CPU multiplexing and high-level application performance in multi-tenant cloud. The dissertation continues by establishing a unique linear mathematical relationship between CPU steal time an d overall application performance. Our approach is to monitor the progress of submitted applications at runtime, tracks the slowdown of individual application and applies adjustment until convergence. Thus, when an application suffered more slowdown, we allocate more CPU to reduce unfairness. In establishing system support for fine-grained profiling, we report system level actvities at sub-second granularity. We predicted application performance degradation by creating a mathematical relationship between high-level application performance and low-level machine event s (i.e., CPU steal time and Misses per thousand instructions). We validate the added value of our approach by comparing application performance slowdowns (average) with various datasets. Based on our experimental results , our approach helps mitigate co-tenant interference and reduces unfairness by minimizing the overall application slowdowns. Lastly, the dissertation concludes by proposing Adaptive CPU Sharing (ACS) in multi-tenants’ clouds. ACS leverages the Xen CPU scheduler capability to reduce unfairness in resource sharing among cloud tenants and reduce application performance degradation.

Download or read book Autonomous Control for a Reliable Internet of Services written by Ivan Ganchev and published by Springer. This book was released on 2018-05-30 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book was prepared as a Final Publication of the COST Action IC1304 “Autonomous Control for a Reliable Internet of Services (ACROSS)”. The book contains 14 chapters and constitutes a show-case of the main outcome of the Action in line with its scientific goals. It will serve as a valuable reference for undergraduate and post-graduate students, educators, faculty members, researchers, engineers, and research strategists working in this field. The explosive growth of the Internet has fundamentally changed the global society. The emergence of concepts like SOA, SaaS, PaaS, IaaS, NaaS, and Cloud Computing in general has catalyzed the migration from the information-oriented Internet into an Internet of Services (IoS). This has opened up virtually unbounded possibilities for the creation of new and innovative services that facilitate business processes and improve the quality of life. However, this also calls for new approaches to ensuring the quality and reliability of these services. The objective of this book is, by applying a systematic approach, to assess the state-of-the-art and consolidate the main research results achieved in this area.

Download or read book High Performance Modelling and Simulation for Big Data Applications written by Joanna Kołodziej and published by Springer. This book was released on 2019-03-25 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book was prepared as a Final Publication of the COST Action IC1406 “High-Performance Modelling and Simulation for Big Data Applications (cHiPSet)“ project. Long considered important pillars of the scientific method, Modelling and Simulation have evolved from traditional discrete numerical methods to complex data-intensive continuous analytical optimisations. Resolution, scale, and accuracy have become essential to predict and analyse natural and complex systems in science and engineering. When their level of abstraction raises to have a better discernment of the domain at hand, their representation gets increasingly demanding for computational and data resources. On the other hand, High Performance Computing typically entails the effective use of parallel and distributed processing units coupled with efficient storage, communication and visualisation systems to underpin complex data-intensive applications in distinct scientific and technical domains. It is then arguably required to have a seamless interaction of High Performance Computing with Modelling and Simulation in order to store, compute, analyse, and visualise large data sets in science and engineering. Funded by the European Commission, cHiPSet has provided a dynamic trans-European forum for their members and distinguished guests to openly discuss novel perspectives and topics of interests for these two communities. This cHiPSet compendium presents a set of selected case studies related to healthcare, biological data, computational advertising, multimedia, finance, bioinformatics, and telecommunications.

Download or read book Introduction to Storage Area Networks written by Jon Tate and published by IBM Redbooks. This book was released on 2018-10-09 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The superabundance of data that is created by today's businesses is making storage a strategic investment priority for companies of all sizes. As storage takes precedence, the following major initiatives emerge: Flatten and converge your network: IBM® takes an open, standards-based approach to implement the latest advances in the flat, converged data center network designs of today. IBM Storage solutions enable clients to deploy a high-speed, low-latency Unified Fabric Architecture. Optimize and automate virtualization: Advanced virtualization awareness reduces the cost and complexity of deploying physical and virtual data center infrastructure. Simplify management: IBM data center networks are easy to deploy, maintain, scale, and virtualize, delivering the foundation of consolidated operations for dynamic infrastructure management. Storage is no longer an afterthought. Too much is at stake. Companies are searching for more ways to efficiently manage expanding volumes of data, and to make that data accessible throughout the enterprise. This demand is propelling the move of storage into the network. Also, the increasing complexity of managing large numbers of storage devices and vast amounts of data is driving greater business value into software and services. With current estimates of the amount of data to be managed and made available increasing at 60% each year, this outlook is where a storage area network (SAN) enters the arena. SANs are the leading storage infrastructure for the global economy of today. SANs offer simplified storage management, scalability, flexibility, and availability; and improved data access, movement, and backup. Welcome to the cognitive era. The smarter data center with the improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric. A smarter data center that hosts IBM Storage solutions can provide an environment that is smarter, faster, greener, open, and easy to manage. This IBM® Redbooks® publication provides an introduction to SAN and Ethernet networking, and how these networks help to achieve a smarter data center. This book is intended for people who are not very familiar with IT, or who are just starting out in the IT world.
