虚拟补丁，是一种可以使IT人员摆脱补丁管理困境的解决方案。虚拟补丁技术旨在通过控制受影响的应用程序的输入或输出，来改变或消除漏洞。
这些定制可以是您所需的任何内容，但是本例中，我们将主要关注将临时补丁安装到虚拟机实例中。
These customizations can be just about anything you need, but in this case we will focus on installing interim fixes into the virtual machine instance.
选择应用了补丁的映像作为新模式的基础，这将确保在应用了该模式后创建的所有虚拟机都将包含定制映像中安装的临时补丁。
Selecting the patched image as the basis for your new pattern ensures that all virtual machines created as a result of deploying the pattern will contain the interim fix installed in the custom image.
然而，某些情况下，可能需要直接向云中已部署的虚拟系统应用补丁。
In some cases, however, you might need to apply fixes directly to virtual systems already deployed in the cloud.
