microsoft arc ? what is that ? it is a new service ... here is the answer from a Microsoft rep

 a Microsoft rep told me use bing to search for the arc. It will tell me what the Microsoft Arc is

Azure Arc

Unify on-premises, hybrid, and multicloud infrastructure

Central management for hybrid and multicloud resources

Azure Arc offers simplified management, faster app development, and consistent Azure services. Easily organize, govern, and secure Windows and Linux servers, SQL Server, and Kubernetes clusters across datacenters, the edge, and multicloud environments in Azure. Architect, design, and build cloud-native apps anywhere without sacrificing central visibility and control.

so it is not precise for me to say it is going to replace SCCM, now I wonder where I got that idea
