Migrating an on-premises SQL Server instance to an Azure Virtual Machine (VM) is a common method to migrate to Azure. Microsoft has helped simplify things by creating multiple types of virtual machines. Memory optimized – High memory-to-CPU ratio, relational database servers, medium to large caches, and in-memory analytics.
