    99.99% uptime, information from High-availability and Azure SQL Database

Just adding some comments on Hannel´s response: 

 

For SQL Database (Basic, Standard, Premium, and Premium) Microsoft provides an availability SLA of 99.99%.

 

For SQL Server running on Azure VMs, Microsoft provides an availability SLA of 99.95% that covers just the Virtual Machine. This SLA does not cover the processes (i.e. SQL Server) running on the VM and requires that you host at least 2VMs  in an availability set.

 

For database HA within VMs, you should configure one of the supported HA options in SQL Server, such as AlwaysOn. Using a supported HA option doesn't provide an additional SLA, but allows you to achieve >99.99% database availability. I suggest you to check: https://azure.microsoft.com/en-us/support/legal/sla/sql-database/v1_1/
