跨区域对PII数据进行地理复制 [英] Geo replication of PII data across Regions

问题描述

有没有一种方法可以跨区域安全地复制PII数据?一种情况是，欧洲的用户将更新其个人资料，而亚洲的用户将尽快看到更新的信息. Blob存储区是存储此信息的正确位置吗? 虽然可以使用CDN进行复制，但是在复制PII数据时需要采取哪些安全措施?

Is there a way to securely replicate PII data across region? A scenario is that a user in Europe would update their profile and a user in Asia would see the updated information as soon as possible. Would Blob storage be the right location to store this information? While CDN can be used to replicate, what security measures need to be taken while replicating PII data?

推荐答案

地理冗余存储(GRS)旨在提供 通过将数据复制到与主要区域相距数百英里的次要区域，在给定的一年中，对象至少具有99.99999999999999％(16 9's)的持久性.如果您的存储帐户启用了GRS，则即使在 区域完全停电或主要区域无法恢复的灾难.

Geo-redundant storage (GRS) is designed to provide at least 99.99999999999999% (16 9's) durability of objects over a given year by replicating your data to a secondary region that is hundreds of miles away from the primary region. If your storage account has GRS enabled, then your data is durable even in the case of a complete regional outage or a disaster in which the primary region is not recoverable.

如果您选择GRS，则有两个相关选项可供选择:

• GRS将您的数据复制到辅助区域中的另一个数据中心，但是仅当Microsoft从服务器启动故障转移时，该数据才可供读取.
• 阅读访问地理冗余存储(RA-GRS)基于GRS. RA-GRS将您的数据复制到辅助区域中的另一个数据中心，并为您提供 从二级区域读取的选项.借助RA-GRS，无论Microsoft是否启动从主数据库到辅助数据库的故障转移，您都可以从辅助数据库读取内容.

• GRS replicates your data to another data center in a secondary region, but that data is available to be read only if Microsoft initiates a failover from the primary to secondary region.
• Read-access geo-redundant storage (RA-GRS) is based on GRS. RA-GRS replicates your data to another data center in a secondary region, and also provides you with the option to read from the secondary region. With RA-GRS, you can read from the secondary regardless of whether Microsoft initiates a failover from the primary to the secondary.

何时创建存储帐户后，请选择该帐户的主要区域.配对的次级区域是 根据主要区域确定，并且无法更改.有关Azure支持的区域的最新信息，请参见 业务连续性和灾难恢复(BCDR).

When you create a storage account, you select the primary region for the account. The paired secondary region is determined based on the primary region, and cannot be changed. For up-to-date information about regions supported by Azure, see Business continuity and disaster recovery (BCDR).

Azure内容分发网络(CDN)是从Azure存储缓存内容. Azure CDN为开发人员提供了用于交付高带宽的全球解决方案 内容.它可以在美国，欧洲，亚洲，澳大利亚和南美的物理节点上缓存计算实例的Blob和静态内容.

Azure Content Delivery Network (CDN) is to cache content from Azure storage. Azure CDN offers developers a global solution for delivering high-bandwidth content. It can cache blobs and static content of compute instances at physical nodes in the United States, Europe, Asia, Australia, and South America.
