Scaling multiple databases with varying and unpredictable usage demands:- Azure SQL Database elastic pools
I'm pretty sure this was on the test I just took. November 2024.
A. An elastic pool that contains 20 Azure SQL databases Reasons: SLA of 99.99% uptime: Azure SQL Database offers a high availability SLA of 99.99%. Dynamic Scaling: Elastic pools dynamically allocate compute resources across the databases based on demand, which helps in managing varying usage patterns. Reserved Capacity: Elastic pools support reserved capacity, which can help reduce costs. Minimized Compute Charges: By pooling resources, elastic pools optimize the overall cost, making compute charges more efficient compared to other options.
