# Large Deployment (100+ users)

This page outlines a common deployment of Parallels Desktop as a Service (DaaS) for large environments with +100 users in a multi-session configuration. It includes licensing and infrastructure requirements. This setup is scalable to larger teams as needed.

We recommend pairing Parallels DaaS with the **Microsoft E3** license for its strong feature set the E3 license includes the desktop versions of Microsoft Word, Excel, Powerpoint and Outlook as wel as 1TB of OneDrive storage space.

For cost saving you can leverage the **Microsoft F3 (Frontline)** license for its strong feature set and affordability, a combination with OneDrive is recommended as the F3 license does not include the desktop versions of Microsoft Office.
