Large organizations have numerous users and a multitude of applications to deploy, update, maintain and adapt. Be it in public organizations or private key accounts, IT services face challenges when deploying applications to large amount of users.

Since QGIS has a wide area of use cases and user typology, it can be complicated to conjugate industrial deployment in an urbanized IT infrastructure, and adaptation of the software to user's needs.

In this presentation, we first detail the challenges faced by large organizations wanting to deploy QGIS for numerous users.

Then we present a strategy to combine efficient automated deployment and configuration management to adapt installed QGIS versions to specific users needs.

This strategy comes with specific opensource tools easing deployments, and incorporated into the toolset of system administrators, especially on windows platforms.

We then talk about future needs and improvements to these tools.
