Starting from the difficulty to manage enterprise systems, applications, and networks a group of IT companies created the WBEM initiative, base of the Microsoft?s WMI implementation. The current paper presents from a practical approach both an architecture design and its implementation for managing distributed systems based on a WMI backbone. The final result was a N-Tier application designed to acquire, store and retrieve functional and performance data from WMI providers without neither overloading targeted systems nor sacrificing the scalability and the reliability. The layers and the dataflow are also presented to provide a better understanding of the whole architecture.
