知识点之Interconnect Dedicated

谷歌今天推出了一项名为Google Cloud Interconnect Dedicated的新服务，服务于大型企业将其数据中心直接连接到其公有云端，换句话说，为企业建立一个可直接连接到谷歌云的专用网络，称为专用互连。

专用互连（目前为测试版）将提供企业在谷歌公有云Google Cloud Platform（GCP）建立高可用的高带宽网络连接，并对接谷歌云平台的延迟敏感和数据密集型应用的服务。

这项服务比Google现有的解决方案（如Google Cloud VPN服务）更进一步，让企业能在私有网络和Google云端之间建立安全通道，来进行数据和云业务应用的迁移及管理。Google表示，这对混合云环境很有用，可将企业数据中心的IP空间扩展到Google Cloud，或高带宽流量。
