Enhancing Business Continuity and It Capability: System Administration and Server Operating Platforms

Enterprise servers play a mission-critical role in modern computing environments, especially from a business continuity perspective. Several models of IT capability have been introduced over the last two decades. Enhancing Business Continuity and IT Capability: System Administration and Server Operating Platforms proposes a new model of IT capability. It presents a framework that establishes the relationship between downtime on one side and business continuity and IT capability on the other side, as well as how system administration and modern server operating platforms can help in improving business continuity and IT capability.

This book begins by defining business continuity and IT capability and their importance in modern business, as well as by giving an overview of business continuity, disaster recovery planning, contingency planning, and business continuity maturity models. It then explores modern server environments and the role of system administration in ensuring higher levels of system availability, system scalability, and business continuity. Techniques for enhancing availability and business continuity also include

• Business impact analysis
• Assessing the downtime impact
• Designing an optimal business continuity solution
• IT auditing as a process of gathering data and evidence to evaluate whether the company's information systems infrastructure is efficient and effective and whether it meets business goals

The book concludes with frameworks and guidelines on how to measure and assess IT capability and how IT capability affects a firm's performances. Cases and white papers describe real-world scenarios illustrating the concepts and techniques presented in the book.

企業伺服器在現代計算環境中扮演著至關重要的角色，尤其從業務連續性的角度來看。在過去的二十年中，引入了幾種IT能力模型。《增強業務連續性和IT能力：系統管理和伺服器操作平台》提出了一種新的IT能力模型。它提出了一個框架，建立了停機時間與業務連續性和IT能力之間的關係，以及系統管理和現代伺服器操作平台如何幫助提高業務連續性和IT能力。

本書首先定義了業務連續性和IT能力以及它們在現代商業中的重要性，並概述了業務連續性、災難恢復計劃、應急計劃和業務連續性成熟度模型。然後探討了現代伺服器環境和系統管理在確保更高水平的系統可用性、系統可擴展性和業務連續性方面的角色。提升可用性和業務連續性的技術還包括：

- 業務影響分析
- 評估停機影響
- 設計最佳業務連續性解決方案
- IT審計作為收集數據和證據以評估公司信息系統基礎設施是否高效、有效並是否符合業務目標的過程

本書以衡量和評估IT能力以及IT能力如何影響公司績效的框架和指南作為結尾。案例和白皮書描述了展示本書中所介紹的概念和技術的現實場景。
