This book addresses Cloud concepts, including advanced forward-looking concepts and how these concepts are realized or implemented in practical systems or frameworks. For example, when a Cloud user or tenant requests a service from a Cloud or Cloud service provider the step-by-step processes of what happens underneath or under-the-hood will be described employing a Cloud framework, such as opensource Openstack, thus bridging the concepts to practical realization of the concepts. The substantial focus of the book is on Cloud networking, the new generation networking that makes a network Cloud-ready, such as VM networking and next-gen DC technologies supporting multitenant Cloud DC. In addition, programmable or software-defined networking that makes on-demand networking possible are also discussed in detail (the on-demand aspect, where compute, storage and network resources are CRUD: Create / Read / Update / Delete almost immediately, is a major feature or requirement of a Cloud). Furthermore, the author discusses how Cloud concepts, features and programmable networking come together to build truly programmable Cloud that spans wide network domains (from tenant intranet or private Cloud to MAN/WAN to one or more public Clouds and their Cloud DCs).
商品描述(中文翻譯)
本書探討雲端概念,包括先進的前瞻性概念以及這些概念如何在實際系統或框架中實現或執行。例如,當雲端用戶或租戶向雲端或雲端服務提供者請求服務時,將描述在背後或內部發生的逐步過程,並使用雲端框架,如開源的 OpenStack,從而將概念與實際實現之間架起橋樑。本書的主要重點在於雲端網路,這是一種使網路具備雲端準備的下一代網路技術,例如虛擬機網路和支持多租戶雲端數據中心的下一代數據中心技術。此外,還詳細討論了可編程或軟體定義網路,使按需網路成為可能(按需方面,即計算、儲存和網路資源幾乎可以立即進行 CRUD:創建 / 讀取 / 更新 / 刪除,是雲端的一個主要特徵或需求)。此外,作者還討論了雲端概念、特徵和可編程網路如何結合在一起,構建真正的可編程雲端,涵蓋廣泛的網路領域(從租戶內部網路或私有雲到城域網 / 廣域網,再到一個或多個公共雲及其雲端數據中心)。
