本地数据网关是什么?What is an on-premises data gateway?

备注

我们最近修订了本地数据网关文档。我们将它们拆分为特定于 Power BI 的内容适用于网关支持的所有服务的常规内容We recently revised the on-premises data gateway docs. We split them into content that's specific to Power BI and general content that applies to all services that the gateway supports. 你当前正在阅读 Power BI 内容。You're currently in the Power BI content. 若要针对本文或整个网关文档体验提供反馈,请滚动到本文底部。To provide feedback on this article, or the overall gateway docs experience, scroll to the bottom of the article.

本地数据网关充当网桥,提供本地数据(不位于云中的数据)与几种 Microsoft 云服务之间快速安全的数据传输。The on-premises data gateway acts as a bridge to provide quick and secure data transfer between on-premises data (data that isn't in the cloud) and several Microsoft cloud services. 这些云服务包括 Power BI、PowerApps、Power Automate、Azure Analysis Services 和 Azure 逻辑应用。These cloud services include Power BI, PowerApps, Power Automate, Azure Analysis Services, and Azure Logic Apps. 通过使用网关,组织可以将数据库和其他数据源保留在其本地网络上,还可以在云服务中安全地使用该本地数据。By using a gateway, organizations can keep databases and other data sources on their on-premises networks, yet securely use that on-premises data in cloud services.

网关概述

网关类型Types of gateways

有两种不同类型的网关,各适用于不同的方案:There are two different types of gateways, each for a different scenario:

  • 本地数据网关 允许多个用户连接到多个本地数据源。On-premises data gateway allows multiple users to connect to multiple on-premises data sources. 可以将本地数据网关与所有支持的服务结合使用,只需要安装单个网关即可。You can use an on-premises data gateway with all supported services, with a single gateway installation. 此网关非常适用于多个用户访问多个数据源的复杂场景。This gateway is well-suited to complex scenarios with multiple people accessing multiple data sources.

  • 本地数据网关(个人模式)允许一个用户连接到源,且无法与其他人共享。On-premises data gateway (personal mode) allows one user to connect to sources, and can’t be shared with others. 本地数据网关(个人模式)只能与 Power BI 一起使用。An on-premises data gateway (personal mode) can be used only with Power BI. 此网关非常适用于你是创建报表的唯一人员且不需要与其他人共享数据源的场景。This gateway is well-suited to scenarios where you’re the only person who creates reports, and you don't need to share any data sources with others.

使用网关Use a gateway

使用网关有以下四个主要步骤。There are four main steps for using a gateway.

  1. 在本地计算机上下载并安装网关Download and install the gateway on a local computer.
  2. 根据防火墙和其他网络要求配置网关。Configure the gateway based on your firewall and other network requirements.
  3. 添加网关管理员,以便管理网关和管理其他网络要求。Add gateway admins who can also manage and administer other network requirements.
  4. 使用网关刷新本地数据源。Use the gateway to refresh an on-premises data source.
  5. 出现错误时,对网关进行故障排除Troubleshoot the gateway in case of errors.
