冗余Azure服务器

本文介绍了冗余Azure服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我的商业模式完全取决于Azure服务正常运行而没有任何问题。 Microsoft / Azure是否提供了在该国家/地区的另一部分运行第二个Azure服务的方法，以及如果主服务失败，我们是否可以切换到该服务？基本上是冗余服务器，具有自动切换功能？

解决方案

您可以在Azure中配置/获取多层冗余。例如：

• 服务 - 您可以配置可用性集，以便您可以让多个VM /应用程序实例响应传入请求。
• 存储 - 默认情况下，您将拥有3个本地冗余副本（LRS），并且可以选择将存储复制类型设置为Geo-Redundant，它为您提供3个本地和3个地理远程，总共6个数据副本以实现冗余。

你可能会发现 这篇文章是更好地了解Azure可用性和可扩展性的起点。

• SQL数据库 - 这是Azure提供的SQL数据库服务，具有自动内置的容错功能。
• SQL Server - 您可以配置 SQL AlwaysOn可用性组。

冗余设置在具有多个地理远程Azure数据中心设施的区域内。如果您想在区域之间实现冗余，例如美国和欧洲，根据我的知识，您将需要部署多个服务并自行管理应用程序状态。

Azure SLA可在aka.ms/SLAs 供您审核。

在Azure中构建的冗余，可用性，可审计性，可伸缩性等具有可观且具有成本效益的功能。对于部署到Azure的那些虚拟机，您可以通过使用Azure恢复服务（）进行备份和恢复，这可能是一种更高效的灾难恢复选项。

HTH。

My business model depends totally on the Azure service being up and running with no problems. Does Microsoft/Azure offer a way to have a second Azure service running in another part of the country, and the ability for us to switch to that service if the primary service fails? Basically redundant servers with auto switch-over?

解决方案

There are multiple layer of redundancy you may configure/acquire in Azure. For instance:

• Service - You can configure Availability Set such that you can have multiple instance of VMs/applications responding to incoming requests.
• Storage - You will have by default3 local redundant copies(LRS) andcan optionallyset the storage replication type to Geo-Redundant which gives you 3 local and 3 geo-remote, total 6 copies of your data for redundancy.

You may find this article a starting point to better understand the availability andscalability of Azure.

• SQL Database - This is the SQL Database service offered byAzurewith fault-tolerance automatically built in.
• SQL Server - You can configureSQL AlwaysOn availability group.

The redundancyis set within a region which has multiple geo-remote Azure datacenter facilities.If you want to have redundancy between regions for instance, US and Europe, you will need to deploy multiple services and manage the application states yourself, to the best of my knowledge.

The Azure SLAs are available at aka.ms/SLAs for your review.

There are considerable and cost-effective capabilities in redundancy, availability, auditability, scalability, etc. built in Azure. For those VMs deployed to Azure, you have a rather productive way of backup and restore by employing Azure Recovery Services, which may be a more productive DR option.

HTH.
