<li>流量窃听：流量传输到云的过程中或在云内部传输时截取流量，破坏保密性</li>
<li>恶意媒介：消息被恶意服务者截获并篡改，破坏保密性和完整性</li>
<li>DDoS：分布式拒绝服务攻击，通过了大量的流量请求使被攻击的IT资源无法正常运行</li>
<li>授权不足：错误的授予了攻击者访问权限，或者授权过于宽泛。</li>
<li>虚拟化攻击：利用虚拟化平台的漏洞危害虚拟化平台安全。</li>
<li>信任边界重叠：云中的物理资源是由不同云服务共享的。恶意用户将目标设定为共享的那些IT资源。</li>

<ul>
<li>宽带网络和Internet架构</li>
<li>数据中心技术</li>
<li>虚拟化技术</li>
<li>Web技术</li>
<li>多租户技术</li>
<li>服务技术</li>
</ul>
<p><strong>特点</strong>：<br>所有的云必须连接到网络，同时利用数据中心技术集中存放IT资源，应用虚拟化技术将物理IT资源转换为虚拟IT资源，从而提供了硬件无关性、服务器整合、资源复制、对资源更强的支持和可扩展性；使用Web技术作为云服务的实现介值和管理接口；设计多租户技术使多个用户在逻辑上同时访问一个应用；其中的服务技术是云计算的基石，形成了“作为服务”的云交付模型的基础</p>

<li><p>VMWare：<br>强大的虚拟化软件，简单的虚拟环境安装，与宿主机方便的通信，方便的网络、显示等驱动应用，适合多环境的开发者或者个人学习使用</p>
</li>
<li><p>VNC Server：<br>适合云服务使用，可以快速的搭建多个虚拟计算资源</p>
</li>
<li><p>WSL：全程Windows Subsystem for Linux，wsl非常适合轻度linux开发者使用，WSL2开始采用全面虚拟环境。方便的安装，多环境，和与宿主Windows通信。</p>
