The recent price increase for Azure SQL Database General Purpose Gen5 2 vCores since September 2024 is mainly attributed to a combination of factors. First, Azure has upgraded the hardware used in Gen5 configurations, including more powerful Intel processors like Ice Lake and Cascade Lake, which deliver improved performance but come with a higher cost. Additionally, the general trend of rising operational costs, such as electricity, cooling, and infrastructure maintenance in cloud data centers, has contributed to this price adjustment.
Moreover, enhanced features such as zone redundancy, which improves data availability by replicating it across availability zones, add to the overall cost in the General Purpose tier. These upgrades aim to offer better performance and reliability but also impact pricing. The increased demand for scalable and secure cloud database services further contributes to these price changes as cloud providers adapt to the growing usage and higher customer expectations.
