<div id="body8662426"><p id="em_01_0035__p18517456161616">Enterprise Management enables enterprises to manage cloud resources at the organization and project levels. Enterprise Management mainly provides project management, personnel management, and resource management.</p>

<p id="em_01_0035__p0831142581711">Both IAM and Enterprise Management can be used to manage users and access permissions. However, Enterprise Management supports more fine-grained resource permissions management than IAM. Enterprise Management is recommended for medium- and large-sized enterprises.</p>
