This document discusses management as a model for today's datacenters. It notes that Zenoss provides unified monitoring for datacenters, with 75k community members, 25k organizations, and 1.2M downloads. It states that management of shared, dynamic infrastructures like virtualization and cloud presents challenges around change, complexity, multi-tenancy, and cost that require new approaches centered around automation.
