Which data storage approach should be included in your recommendation for WebApp1?

The vCore purchasing model for Azure SQL Database offers granular control over compute, memory, and storage, making it ideal for applications like WebApp1 that require predictable performance and the ability to scale independently. This model provides more flexibility and transparency in resource consumption compared to DTUs. An Azure virtual machine hosting SQL Server would introduce significant management overhead. An Azure SQL Database using a fixed DTU purchasing model can be less cost-effective and harder to scale precisely for fluctuating workloads. An Azure SQL Database elastic pool is designed for managing multiple databases with unpredictable usage, not a single application like WebApp1 that needs dedicated, scalable resources.
