Content Description

数据中心权威专家Gustavo A. A. Santana深入研究了数据中心端到端虚拟化解决方案中的所有组件，包括网络、存储、服务器、操作系统、应用优化和安全性。《数据中心虚拟化技术权威指南》并没有把重点放在单个产品或技术上，而是探索了以产品能力作为交互式设计工具，这些工具可以整合和集成到其他解决方案之中，如VMware vSphere等。
在《数据中心虚拟化技术权威指南》中，您将学习如何在数据中心新建、扩容以及改造项目中，去定义和实现高效的体系架构。这样，需购买不必要的基础设施，就可以实现灵活的应用配置，并能够为云计算以及IT-as-a-service等新方案奠定坚实的基础。
