-In the business critical service tier, we automatically allocate at least 3 replicas. To reflect this additional allocation of compute resources, the price in the vCore-based purchasing model is approximately 2.7x higher in the business critical service tier than it is in the general purpose service tier. Likewise, the higher storage price per GB in the business critical service tier reflects the high I/O and low latency of the SSD storage.

 A virtual core (vCore) represents a logical CPU and offers you the option to choose between generations of hardware and the physical characteristics of the hardware (for example, the number of cores, the memory, and the storage size). The vCore-based purchasing model gives you flexibility, control, transparency of individual resource consumption, and a straightforward way to translate on-premises workload requirements to the cloud. This model allows you to choose compute, memory, and storage resources based upon your workload needs.
