- MDOP: This is tied to Windows desktop Software Assurance. If you let your Windows SA lapse, your renewal of MDOP will also end.
- VDA (Virtual Desktop Assurance): Microsoft’s licensing for full blown VDI. If you want to spin up a virtual Windows desktop on a server, you need to have the VDA subscription in place. VDA can be purchased on its own (generally for thin clients) or as part of Windows SA (see MDOP above).
- Windows Companion Subscription License (CSL): This add-on to the VDA subscription allows your virtual desktop to be viewed on secondary devices like iPads.
- System Center Endpoint Protection: Anti-virus, anti-malware, this is part of your Core CAL EA, so if you have it deployed and choose not to renew your Core CAL, you will have to uninstall it.
- Exchange Hosted Encryption and Online Protection for Exchange: Both of these can be purchased as standalone subscriptions or as part of Exchange Enterprise CAL Software Assurance. Again, if you let this SA lapse, you’ll need to uninstall.
- Office 365 packages: These include hosted Exchange, SharePoint, and Lync, and may include Office as well.
- Azure: Microsoft’s hosted Windows Server infrastructure.
All of the subscriptions listed above are becoming more popular every year, VDA and Office 365 particularly. If moving to the cloud or implementing VDI is on your roadmap, make sure you keep in mind the nature of subscription licensing vs. the perpetual licensing of the past.
