Business Critical
A high-performance service tier in the Azure SQL Database vCore model that uses multiple local SSD replicas and targets transaction-intensive, low-latency IO and high-availability scenarios.
Timeline (last 90 days)
In the Business Critical tier, the Standard series log throughput limit is raised from 96 MB/s to 160 MB/s (reached at 16 vCores); the Premium series maintains the 192 MB/s limit, but the vCores required to reach that limit drop from 16 to 12.
The General Purpose service tier uses remote storage (Azure Premium SSD or Ultra Disk) with compute and storage separated; Business Critical uses local SSD storage with built-in Always On availability group replicas.
