# Medium Deployment (20-100 Users)

This page outlines a common deployment of Parallels Desktop as a Service (DaaS) for medium sized environments with 20 - 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. 

{% hint style="success" %}
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.
{% endhint %}

* **Parallels DaaS License** (Per named user)

### Infrastructure Overview

Virtual machine (VM) sizing impacts cost and performance. Parallels DaaS automatically scales resources based on user demand. Typical VMs run \~200 hours/month using scaling.

#### Common VM Options

<table><thead><tr><th>VM Type</th><th>Specs</th><th>Approx. Users</th><th>200 Hrs (PAYG)</th><th width="128.2265625">24/7 (PAYG)</th><th>1 Yr Reserved</th><th>3 Yr Reserved</th></tr></thead><tbody><tr><td><strong>D8s_v5</strong> <em>(Recommended)</em></td><td>8 vCPU / 32 GB RAM</td><td>~32 users</td><td>$119</td><td>$430</td><td>$257</td><td>$161</td></tr></tbody></table>

*User density depends on workload. Heavy multitasking or conferencing video usage may reduce capacity.*
