迁移目标Migration goals

为了帮助确定最佳迁移方法,Contoso 云团队固定了以下目标:To help determine the best migration method, the Contoso cloud team pinned down the following goals:

要求Requirements 详细信息Details
应用程序Application Azure 中的应用程序将保持关键,因为目前在本地。The application in Azure will remain as critical as it is today on-premises.

它应当具有与当前在 VMware 中的性能相同的性能。It should have the same performance capabilities as it currently does in VMware.

团队不希望在应用程序中投入投资。The team doesn't want to invest in the application. 目前,管理员只需将应用程序安全地移到云中。For now, admins will simply move the application safely to the cloud.

团队想要停止支持的 Windows Server 2008 R2,应用程序当前运行在该服务器上。The team wants to stop supporting Windows Server 2008 R2, which the application currently runs on.

此团队还想要从 SQL Server 2008 R2 移动到现代平台即服务 (PaaS) 数据库,这将最大程度地减少管理需求。The team also wants to move away from SQL Server 2008 R2 to a modern platform as a service (PaaS) database, which will minimize the need for management.

Contoso 希望尽可能利用其在 SQL Server 许可和软件保障方面的投资。Contoso wants to take advantage of its investment in SQL Server licensing and Software Assurance where possible.

此外,Contoso 还希望减少 Web 层上的单一故障点。In addition, Contoso wants to mitigate the single point of failure on the web tier.
限制Limitations 应用程序包含 ASP.NET 应用程序和 Windows Communication Foundation (WCF) 服务在同一 VM 上运行。The application consists of an ASP.NET application and a Windows Communication Foundation (WCF) service running on the same VM. 他们希望使用 Azure App Service 将这些组件分散到两个 web 应用中。They want to spread these components across two web apps using the Azure App Service.
AzureAzure Contoso 想要将应用程序移动到 Azure,但不希望在 Vm 上运行它。Contoso wants to move the application to Azure, but they don't want to run it on VMs. Contoso 希望为 Web 层和数据层使用 Azure PaaS 服务。Contoso wants to use Azure PaaS services for both the web and data tiers.
DevOpsDevOps Contoso 想要迁移到 DevOps 模型,该模型使用 Azure DevOps 生成和发布管道。Contoso wants to move to a DevOps model that uses Azure DevOps for their builds and release pipelines.

解决方案设计Solution design

在固定其目标和需求后,Contoso 设计和审查部署解决方案。After pinning down their goals and requirements, Contoso designs and reviews a deployment solution. 它们还确定了迁移过程,包括用于迁移的 Azure 服务。They also identify the migration process, including the Azure services that they'll use for the migration.

当前应用程序Current application

  • SmartHotel360 本地应用程序跨两个 Vm 和进行分层 WEBVM SQLVMThe SmartHotel360 on-premises application is tiered across two VMs, WEBVM and SQLVM.
  • Vm 位于 VMware ESXi host contosohost1.contoso.com 版本6.5 上。The VMs are located on VMware ESXi host contosohost1.contoso.com version 6.5.
  • VMware 环境由在虚拟机上运行的 vCenter Server 6.5 (vcenter.contoso.com) 进行管理。The VMware environment is managed by vCenter Server 6.5 (vcenter.contoso.com), which runs on a VM.
  • Contoso 有一个本地数据中心 (contoso-datacenter),其中包含一个本地域控制器 (contosodc1)。Contoso has an on-premises datacenter (contoso-datacenter), with an on-premises domain controller (contosodc1).
  • 迁移完成后,Contoso 数据中心的本地 VM 将停止使用。The on-premises VMs in the Contoso datacenter will be decommissioned after the migration is done.

建议的解决方案Proposed solution

  • 对于应用程序的数据库层,Contoso 比较 Azure SQL 数据库到 SQL Server,方法是参阅 功能比较: AZURE Sql 数据库和 AZURE sql 托管实例For the database tier of the application, Contoso compared Azure SQL Database to SQL Server by referring to Features comparison: Azure SQL Database and Azure SQL Managed Instance. Contoso 决定使用 Azure SQL 数据库,原因如下:Contoso decided to use Azure SQL Database for a few reasons:
    • Azure SQL 数据库是托管关系数据库服务。Azure SQL Database is a managed relational database service. 它在多个服务级别提供可预测的性能,几乎不需要管理。It delivers predictable performance at multiple service levels, with near-zero administration. 优点包括在不停机的情况下实现动态可伸缩性、内置的智能优化以及全局可伸缩性和可用性。Advantages include dynamic scalability with no downtime, built-in intelligent optimization, and global scalability and availability.
    • Contoso 可以使用轻型数据迁移助手来评估将本地数据库迁移到 Azure SQL。Contoso can use the lightweight Data Migration Assistant to assess the on-premises database migration to Azure SQL.
    • Contoso 可以使用 Azure 数据库迁移服务将本地数据库迁移到 Azure SQL。Contoso can use Azure Database Migration Service to migrate the on-premises database to Azure SQL.
    • 对于软件保障,Contoso 可以通过使用 SQL Server 的 Azure 混合权益,与 SQL 数据库中数据库的折扣率交换现有许可证。With Software Assurance, Contoso can exchange existing licenses for discounted rates on a database in SQL Database by using the Azure Hybrid Benefit for SQL Server. 此方法可以节省高达30% 的成本。This approach could provide a cost saving of up to 30 percent.
    • SQL 数据库提供安全功能,例如 Always Encrypted、动态数据掩码、行级别安全性和 SQL 威胁检测。SQL Database provides security features such as Always Encrypted, dynamic data masking, row-level security, and SQL threat detection.
  • 对于应用程序的 web 层,Contoso 已决定使用 Azure App Service。For the application web tier, Contoso has decided to use Azure App Service. 使用此 PaaS 服务,只需进行少量的配置更改便可部署应用程序。This PaaS service enables them to deploy the application with just a few configuration changes. Contoso 将使用 Visual Studio 进行更改,并部署两个 web 应用,一个用于网站,另一个用于 WCF 服务。Contoso will use Visual Studio to make the change, and they'll deploy two web apps, one for the website and one for the WCF service.
  • 为了满足 DevOps 管道的要求,Contoso 将使用 Azure DevOps 进行源代码管理,并使用 Git 存储库。To meet requirements for a DevOps pipeline, Contoso will use Azure DevOps for source code management with Git repos. 他们将使用自动生成和发布生成代码并将其部署到 Azure App Service。They'll use automated builds and release to build the code and deploy it to the Azure App Service.

解决方案评审Solution review

Contoso 通过结合使用 "优点" 和 "缺点" 列表来评估其建议的设计,如下表所示:Contoso evaluates their proposed design by putting together a pros and cons list, as shown in the following table:

注意事项Consideration 详细信息Details
优点Pros SmartHotel360 应用程序代码不需要更改即可迁移到 Azure。The SmartHotel360 application code doesn't require changes for migration to Azure.

Contoso 可以通过对 SQL Server 和 Windows Server 使用 Azure 混合权益,充分利用其对软件保障的投资。Contoso can take advantage of their investment in Software Assurance by using the Azure Hybrid Benefit for both SQL Server and Windows Server.

迁移后,不需要支持 Windows Server 2008 R2。After the migration, Windows Server 2008 R2 won't need to be supported. 有关详细信息,请参阅 Microsoft 生命周期策略For more information, see the Microsoft Lifecycle Policy.

Contoso 可以配置具有多个实例的应用程序的 web 层,使 web 层不再是单一故障点。Contoso can configure the web tier of the application with multiple instances, so that the web tier is no longer a single point of failure.

数据库不再依赖于老化的 SQL Server 2008 R2。The database will no longer depend on the aging SQL Server 2008 R2.

SQL 数据库支持相关技术要求。SQL Database supports the technical requirements. Contoso 使用数据迁移助手评估了本地数据库,并发现它是兼容的。Contoso assessed the on-premises database by using Data Migration Assistant and found that it's compatible.

Azure SQL 数据库具有内置的容错能力,Contoso 无需设置。Azure SQL Database has built-in fault tolerance that Contoso doesn't have to set up. 这将确保数据层不再是单一故障转移点。This ensures that the data tier is no longer a single point of failover.

如果 Contoso 使用 Azure 数据库迁移服务来迁移数据库,它将具有可用于大规模迁移数据库的基础结构。If Contoso uses Azure Database Migration Service to migrate their database, it will have the infrastructure ready for migrating databases at scale.
缺点Cons 对于每个 web 应用,Azure App Service 仅支持一个应用程序部署。Azure App Service supports only one application deployment for each web app. 这意味着必须预配两个 web 应用,一个用于网站,另一个用于 WCF 服务。This means that two web apps must be provisioned, one for the website and one for the WCF service.
