"Inter-VLAN Routing (nTier Apps) is the capability to route network traffic "
"between VLANs. This feature enables you to build Virtual Private Clouds "
"(VPC), an isolated segment of your cloud, that can hold multi-tier "
"applications. These tiers are deployed on different VLANs that can "
"communicate with each other. You provision VLANs to the tiers your create, "
"and VMs can be deployed on different tiers. The VLANs are connected to a "
"virtual router, which facilitates communication between the VMs. In effect, "
"you can segment VMs by means of VLANs into different networks that can host "
"multi-tier applications, such as Web, Application, or Database. Such "
"segmentation by means of VLANs logically separate application VMs for higher"
" security and lower broadcasts, while remaining physically connected to the "
"same device."
msgstr "vlan间路由(多层应用)提供了在vlan间通过流量路由的功能。这个特性使你能够j建立私有云(vpc)，独立分割的云，可容纳多层应用程序。这些层被部署在不同的VLAN，可以互相沟通。您提供的VLAN层的创建和部署虚拟机可以在不同的层上。VLAN连接到一个虚拟路由器，这有利于虚拟机之间的通信。实际上，你可以通过不同定义的vlan来分割你的虚拟机到不同网络，以便承担多层应用，如Web，应用程序或数据库的虚拟机。通过VLAN的逻辑上独立的应用程序的虚拟具有较高的安全性和较低的广播，同时任然物理连接到同一设备。"
