The vCore-based purchasing model for Azure SQL Database Elastic pools and Single databases is now generally available. The purchasing model is in addition to the existing DTU-based model. Designed to give you flexibility, control, transparency, and an easier way to compare to on-premises workloads, it allows you to scale compute, storage, and IO independently based upon your workload needs. Options within the vCore-based model are also eligible for up to 30 percent savings with the Azure Hybrid Benefit for SQL Server.
