商品描述
Companies and institutions depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based. Business Continuity is the ability to do business under any circumstances and is an essential requirement faced by modern companies. Both concepts - High Availability and Disaster Recovery - are realized by redundant systems. This book presents requirements, concepts, and realizations of redundant systems on all abstraction levels, and all given examples refer to UNIX and Linux Systems.
商品描述(中文翻譯)
企業和機構比以往任何時候都更依賴其資訊科技的可用性，而大多數關鍵業務流程都是基於資訊科技的。業務持續性是指在任何情況下都能繼續運營的能力，這是現代企業面臨的一項基本要求。高可用性（High Availability）和災難恢復（Disaster Recovery）這兩個概念都是通過冗餘系統來實現的。本書介紹了冗餘系統在所有抽象層級上的需求、概念和實現，所有給出的例子均參考 UNIX 和 Linux 系統。
