选择您的位置

注意：本页面包含有关 AWS 产品的说明。Google 不保证此指南是最新的，也不保证示例配置选项最适合您的应用场景。如需了解最新信息，请参阅 AWS 文档。

在您使用 Cross-Cloud Interconnect 时，Google 会代表您在 Google Cloud 网络和 Amazon Web Services (AWS) 网络之间预配物理连接。

您必须先从 Google 和 AWS 订购端口，然后 Google 才能建立这些连接。在开始该过程之前，请确定要用于连接的 Google Cloud 位置和相应的 AWS 位置。

选择位置的最佳实践

在确定连接布置位置时，请考虑以下问题：

• 您的大多数 Google Cloud 资源在哪里？
• 您的大多数 AWS 资源在哪里？

如果来自两个云的资源位于同一位置，则可以轻松选择。 但如果不在相同位置，您就需要考虑连接应该更靠近Google Cloud 资源还是 AWS 资源。如果连接更靠近 AWS 资源，则流量会花费更多时间在 Google 网络上传输，这通常是需要的。但是，您还应该考虑两个云可能产生的出站数据传输费用。

受位置影响的因素

本部分介绍会受到位置选择影响的因素。

VLAN 连接

建立 Cross-Cloud Interconnect 连接后，您必须在 Google Cloud中配置 VLAN 连接。VLAN 连接是远程云网络与 Virtual Private Cloud 网络中的单个区域之间的逻辑连接。

为端口选择位置时，您可以限制放置 VLAN 连接的区域数量。因此，“支持的位置”表中有一列是每个端口位置服务的Google Cloud 区域。

注意：在 Google Cloud中，VLAN 连接的位置不必限制接收 AWS 路由的 Google Cloud 区域。如需将 AWS 路由通告到您所有的 Google Cloud 区域，请配置全球动态路由。

边缘可用性网域

每个都市区域都有两个 Google Cloud 边缘可用性网域。同一个都市区域内的两个网域不会被安排同时停机维护。因此，为主要端口和冗余端口选择位置时，每个端口都必须使用同一都市区域内的不同边缘可用性网域。无论您如何订购端口，都是如此。但是，使用 Google Cloud CLI 时，您必须明确指定每个边缘可用性网域。使用 Google Cloud 控制台时，您只需选择一个位置， Google Cloud 会在每个网域中为您预留一个端口。

在 gcloud CLI 版本的位置名称中，边缘可用性网域是信息中的第二部分。例如，如果位置名称为 iad-zone1-1，则边缘可用性网域为 zone1。如果位置名称为 iad-zone2-1，则边缘可用性区域为 zone2。

对接网点

Google 通常会在单个对接网点内预配每个连接。但是，有时会在同一提供商运营的相邻网点之间创建连接。无论哪种情况，您通常都不需要知道网点名称。因此，支持的位置表不会标识特定网点。

支持的位置列表

下表列出了受支持的 AWS 位置和相应的Google Cloud 位置。

您必须指定 Cross-Cloud Interconnect 端口的 Google Cloud 位置，并另外指定其他云服务提供商的连接位置。在本文档集和 Google Cloud中，后一个 AWS 位置称为远程位置。订购 Cross-Cloud Interconnect 时，请务必使用远程位置名称。您的远程云服务提供商会使用一个不同但相似的位置名称，您在向该云服务提供商订购端口时使用该名称。

每个位置名称都存在一些语法上的差异。例如：

• 根据您是与 AWS 还是 Google Cloud进行交互，远程位置名称会有所不同。
• 与 Google Cloud交互时， Google Cloud 控制台会在位置名称旁边显示远程位置说明，以帮助您选择正确的位置。
• 在 Google Cloud中， Google Cloud 控制台 Cloud Interconnect 位置（不是远程位置）显示的是网点信息，而不是实际的 Cloud Interconnect 位置名称。

注意：您也可以使用 gcloud CLI 列出位置。如需了解详情，请参阅 gcloud compute interconnects remote-locations list 命令的参考页面。

验证可用性

确定要使用的位置后，请仔细检查以确保该位置有可用的 10 Gbps 或 100 Gbps Direct Connect 端口。这个步骤很有用，因为端口可用性随时可能变化，而您不会提前收到通知。

如果您在使用 AWS 控制台，则可以在订购连接时验证可用性。如需提前验证可用性，请使用 AWS CLI。

AWS CLI

使用 describe-locations 命令获取有关 AWS 位置中可用连接的信息。例如：

aws directconnect describe-locations --region REGION | jq -r '.locations[] | select(.locationCode | test("REMOTE_LOCATION"; "i")) | .availablePortSpeeds'

请替换以下内容：

• REGION：AWS 区域的名称，例如 us-east-2
• REMOTE_LOCATION：远程位置的 AWS 名称，例如 CSVA1

命令输出会显示可用端口的速度。

      [
        "100 Gbps",
        "10 Gbps",
        "1 Gbps"
      ]

记下位置和区域

查看完前面的部分后，请记下以下值：

• Google Cloud中已知的远程位置和 Google Cloud 位置。您在订购 Cross-Cloud Interconnect 连接时需要用到这些值。
• AWS 中的远程位置和您希望放置连接资源的区域。在订购 AWS 端口和配置 AWS 资源时，您需要这些值。
• 要布置 VLAN 连接的 Google Cloud 区域。您在创建该连接时需要用到此值，如配置 Google Cloud 资源中所述。
