云计算平台中的虚拟化技术与安全机制

随着云计算的普及,其安全问题变得越来越重要。本文通过研究存储虚拟化和网络虚拟化技术,设计并部署了一个弹性和安全的虚拟化集群。该集群利用虚拟化技术把云计算用户空间在逻辑上相互隔离,有效地解决了共享性和安全性之间的矛盾。该集群也具有良好的可扩展性、高可用性和较低的成本。

Virtualization and Security Mechanisms in Cloud Computing

As cloud computing is rapidly spreading, cloud security is becoming more and more concerned. We have designed and built a secure and elastic virtual cluster of VMs, through researching on the technology of storage virtualization and network virtualization. The cloud users＇ space is logically isolated in this virtual cluster. As a result, security is achieved with data sharing, as well as scalability, high availability and lower cost.
