Microsoft Azure SQL Database Premium P1 - overage fee

It is important to be able to quantify how the increasing power of each performance level translates into increased database performance. To do this, Microsoft developed the Azure SQL Database Benchmark (ASDB). The benchmark allows to assess the impact on database performance of the increasing power offered by each performance level by measuring actual database operations, while scaling database size, number of users, and transaction rates in proportion to the hardware resources. The benchmark exercises a mix of basic operations found in all OLTP workloads.
