Azure SQL DB与托管实例 [英] Azure SQL DB vs Managed instance
问题描述
Hi Guys,
我们正处于将某些本地数据库移至云的计划的早期阶段，并希望采用PaaS方式.我了解托管实例处于预览状态.
We are in the early stages of planning to move some of our on-premise database to cloud and wanted to go the PaaS way. I understand that managed instance is in preview.
从我所阅读的内容中，忽略了成本以及它处于预览状态的事实，是否有任何理由不使用托管实例?
借助跨数据库查询，它是否仍使PaaS/Managed迁移使迁移变得更容易，从而使我们无需维护它?在我看来两全其美.
With cross database query, does it not make the migration easier while still being PaaS/Managed so that we do not have maintain it? Looks like the best of both world to me.
我唯一找不到的问题是如何处理托管实例的灾难恢复?借助Azure SQL DB，我们可以在另一个区域进行地理复制，但是找不到与托管实例有关的任何类似文档.
The only question that I couldn't find is how we could handle disaster recovery for managed instance? With Azure SQL DB we can have Geo-replication in another region, but couldnt find anything similar documented for managed instance.
在初期阶段，我们计划迁移需要高可用性且延迟查询非常低的OLTP应用程序
In the initial stages we are planning to move an OLTP application which needs to be highly available and have very low latency queries
有什么理由不推荐使用托管实例吗?
干杯
推荐答案
您可以使用复制，但仍在公共预览中
当前，所有托管实例功能中的大多数都处于公共预览状态.您需要等待一段时间才能使这些功能正式发布.因此，建议您等待一些新功能正式发布.
Currently, most of all the Managed Instance features were in public preview You need to wait for sometime to get those features were officially released. So I'd recommend waiting for some new features to get officially released.
最近，Microsoft宣布了"Azure SQL数据库托管实例，通用层"的通用可用性
