Cloud cost conversations usually start with resizing virtual machines. The larger saving is often sitting in licensing you already own.
What it covers
Organizations with Windows Server or SQL Server licences under Software Assurance can apply those licences to Azure workloads instead of paying the pay-as-you-go rate that bundles the licence in.
Why it goes unclaimed
It has to be applied per resource, and it is easy to miss on machines created after the initial migration. A periodic review of which workloads have it enabled tends to find some that do not.
