When migrating small SQL Server instances to Azure it is often the case that a single SQL Managed Instance turns out to be overkill in terms of size and, consequently, cost. The oversizing problem can happen whenever very small instances are required, for example when an ISV company builds a multi-tenant app requiring a small SQL MI instance for each customer. In such cases the smallest size (4-vCores) for a single SQL MI can still turn out to be too large and too expensive for the given use case. This is where SQL MI pools (“instance pools”) deliver great value.
