https://docs.microsoft.com/en-us/azure/azure-sql/database/features-comparisonAzure SQL managed instance and Azure SQL database are both database services provided by Microsoft Azure, but they differ in some ways. One key difference between the two is that Azure SQL managed instance provides a fully managed database instance that is hosted in a customer's virtual network, whereas Azure SQL database is a database-as-a-service offering that provides a fully managed database service in the cloud.
Regarding the benefits of hosting a database on Azure SQL managed instance as compared to an Azure SQL database, the correct answer is A. built-in high availability.
Here's a more detailed explanation:
A. Built-in high availability:
Azure SQL managed instance provides built-in high availability features that are not available in Azure SQL database. With Azure SQL managed instance, Microsoft takes care of the high availability of the database instance, including automatic backups, automatic failover, and automatic patching. This means that the database is highly available and can withstand a range of failures without any disruption to the application. In contrast, with Azure SQL database, high availability is achieved through a combination of features such as geo-replication, auto-failover groups, and backups.
B. Native support for cross-database queries and transactions:
Both Azure SQL managed instance and Azure SQL database support cross-database queries and transactions. However, Azure SQL managed instance provides a higher level of compatibility with SQL Server, which means that it can support more complex scenarios for cross-database queries and transactions.
C. System-initiated automatic backups:
Azure SQL managed instance provides system-initiated automatic backups, which are not available in Azure SQL database. These backups are automatically taken at regular intervals, and they can be used to restore the database in case of any failures or data loss.
D. Support for encryption at rest:
Both Azure SQL managed instance and Azure SQL database support encryption at rest using Transparent Data Encryption (TDE). TDE encrypts the database files and backups, protecting them from unauthorized access.
In conclusion, hosting a database on Azure SQL managed instance provides built-in high availability features that are not available in Azure SQL database. However, the choice between the two services ultimately depends on your specific business requirements and technical considerations.
