Microsoft Defender for Endpoint and Microsft Defender for Cloud - agents

Hi I have a question .

Defender for Endpoint has agents that can be installed on Windows Client and servers ( 7,8.1 10,11 WinSvr 2008,2012R@ etc).

Microsoft Defender for Cloud also has Log Analytics agents.

How are these 2 agents different?

Appreciate any references.

Thank you

Suresh
