Best price-performance for mission-critical data
Azure SQL Database vs. AWS RDS
Switch to Azure SQL Database and get better price-performance than other cloud providers. Azure SQL Database meets your mission-critical requirements while costing up to 86 percent less than the competition.1
1Price-performance claim based on data from a study commissioned by Microsoft and conducted by GigaOm in August 2019. The study compared price-performance between a single, 80 vCore, Gen 5 Azure SQL Database on the business critical service tier and the db.r4.16x large offering for Amazon Web Services Relational Database Service (AWS RDS) on SQL Server. Benchmark data is taken from a GigaOm Analytic Field Test derived from a recognized industry standard, TPC Benchmark™ E (TPC-E), and is based on a mixture of read-only and update intensive transactions that simulate activities found in complex OLTP application environments. Price-performance is calculated by GigaOm as the cost of running the cloud platform continuously for three years divided by transactions per second throughput. Prices are based on publicly available US pricing in East US for Azure SQL Database and US East (Ohio) for AWS RDS as of August 2019. Price-performance results are based upon the configurations detailed in the GigaOm Analytic Field Test. Actual results and prices may vary based on configuration and region.
SQL Server on Azure Virtual Machines vs. AWS EC2
Switch to SQL Server on Azure Virtual Machines and get better performance and price-performance than other cloud providers. Azure SQL Virtual Machines meet your mission-critical requirements and is up to 3.4 times faster and 87 percent cheaper than Amazon Web Services.1
1Price-performance claims based on data from a study commissioned by Microsoft and conducted by GigaOm in October 2019. The study compared price performance between SQL Server 2017 Enterprise edition on Windows Server 2016 Datacenter edition in Azure E64s_v3 instance type with 4x P30 1TB Storage Pool data (Read Only Cache) + 1x P20 0.5TB log (No Cache) and the SQL Server 2017 Enterprise edition on Windows Server 2016 Datacenter edition in AWS EC2 r4.16xlarge instance type with 1x 4TB gp2 data + 1x 1TB gp2 log. Benchmark data is taken from a GigaOm Analytic Field Test derived from a recognized industry standard, TPC Benchmark™ E (TPC-E). The Field Test does not implement the full TPC-E benchmark and as such is not comparable to any published TPC-E benchmarks. The Field Test is based on a mixture of read-only and update intensive transactions that simulate activities found in complex OLTP application environments. Price-performance is calculated by GigaOm as the cost of running the cloud platform continuously for three years divided by transactions per second throughput. Prices are based on publicly available US pricing in West US for SQL Server on Azure Virtual Machines and Northern California for AWS EC2 as of October 2019. Pricing incorporates three year reservations for Azure and AWS compute pricing, and Azure Hybrid Benefit for SQL Server and Azure Hybrid Benefit for Windows Server and License Mobility for SQL Server in AWS, excluding Software Assurance costs. Price-performance results are based upon the configurations detailed in the GigaOm Analytic Field Test. Actual results and prices may vary based on configuration and region.
