English英语译成Chinese汉语 技术/工程设计 IT（信息技术） Cloud computing

3. Is virtualization the same as cloud computing?
No, but server virtualization is a key building block to cloud computing that enables ***application isolation, mobility, and partitioning of individual servers*** in the cloud. Applications are placed into virtual machines (VM’s) which simplify the provisioning and configuration of application environments in the cloud, allowing for easier reconfiguration of resources to meet business demand.
3.虚拟化与云计算是一回事吗？
不一回事，服务器虚拟化是云计算的一个关键构建模块，它能够实现应用程序隔离、移动性以及对云环境的单台服务器进行隔离。应用程序放在虚拟机中，而虚拟化可以简化云中应用环境的供应和配置，以便重新配置资源，以满足业务需求。
感觉不理想。
到底是：
1、application isolation、2mobility, and 3、partitioning of individual servers
（见上译）
还是
[application isolation, mobility, and partitioning] of individual servers
？
