Hi Ahmed Essam,
Thank you for posting in Microsoft Q&A forum.
1,Tenant attach and Co-management are two of the three primary cloud attach feature (the third one is Endpoint analytics). A Configuration Manager environment is considered cloud attached when it uses at least one of the three primary cloud attach features. Cloud attach allows you to transform your existing environment without having to worry about much disruption or risk.
2,Tenant attach provides immediate value by having your device records in the cloud and being able to take actions on these devices from the cloud-based console. You can get real-time data from Configuration Manager clients including clients connected from the internet. In addition to device actions, Tenant attach allows you to manage endpoint security for the attached devices from Intune admin center for both Windows Servers and Client devices along with reports on Antivirus status and detected malware.
3,Co-management transforms your on-premises Configuration Manager environment without having to go through a large migration effort. Co-management helps simplify device management by giving you the ability to manage workloads from the cloud.

Simon
