Computing Networks explores the core principles of the new distributed computing infrastructures being used today: the networking systems of clusters, grids and cloud-based services. Cloud Computing will give millions of users the ability to process data anytime, anywhere, while also allowing them to maintain eco-friendly principles. In order to deliver this fast-growing traffic in a timely, cost-efficient, energy-efficient, and reliable manner over long-distance networks, several issues such as Quality of Service (QoS), security, metrology, network-resource scheduling and virtualization have been under scrutiny for the past 15 years.
With all the key global technology players entering the cloud computing space, it is inevitable that the field is attracting a huge amount of attention. But at present the majority of cloud computing users are still accessing computing power from the ubiquitous form of prior paradigm network access: the TCP/IP socket. Although modern distributed infrastructures theoretically offer solutions for resource aggregation, a high and predictable level of performance for applications may be hard to obtain due to the unsuitability of current bandwidth-sharing paradigms (fairness, best effort, no QoS), communication protocols, and software overheads. This book identifies the key problems that must be overcome in order to resolve these limitations.
The book aims to help network designers, and distributed-application developers and users to better understand the technologies, specific challenges, constraints and benefits of these different infrastructures’ communication systems.
