SAP targets ERP, and basically nothing else. You will never[1] see SAP HANA used outside of a SAP deployment, even though it is a general purpose in-memory database with some nice features. Similarly, you never see SAP ABAP used outside of a SAP deployment.
Microsoft targets the most generic use-cases possible, even more so than, say, Linux. You can do anything[2] with Windows, SQL Server, ASP.NET, Azure, etc...
[1] For some values of never.
[2] For some values of anything.
