As customers and partners start using or considering to use Flow and PowerApps, more and more questions are arising about both services. Fortunately, Microsoft is making strong efforts to answer those questions and as a proof of that, you can check Chris McNulty FAQ in the Microsoft Tech Community:
Q. What does Microsoft’s commitment to PowerApps and Microsoft Flow mean for historic business solutions on SharePoint, like InfoPath?
A. As we announced at Ignite, PowerApps and Microsoft Flow are tools for business users to build business applications and automation in SharePoint today and tomorrow. They are the successors to InfoPath and SharePoint Designer for many common business scenarios, especially custom forms used on SharePoint lists.
Q. Will Microsoft still support InfoPath and SharePoint Designer?
A. As we announced earlier in 2016:
SharePoint Server 2016 will include an ongoing capability to host InfoPath Forms Services. InfoPath Forms Services on SharePoint 2016 will be supported for the duration of SharePoint 2016’s support lifecycle.
InfoPath Forms Services on Office 365 will continue to be supported.
InfoPath 2013 and SharePoint Designer 2013 will be the last versions of those products. SharePoint Designer is not being re-released with SharePoint Server 2016, although we will continue to support custom workflows built with SharePoint Designer and hosted on SharePoint Server 2016 and Office 365. Support for InfoPath 2013 and SharePoint Designer 2013 will match the support lifecycle for SharePoint Server 2016, running until 2026.
Q. What can customers expect to see inside SharePoint Online?
A. The release is principally a licensing event. If you have previously enabled preview features inside SharePoint Online, PowerApps and Microsoft Flow will continue to appear in the App Launcher and as elements of modern lists. If you had disabled access to preview features, users will see those integrations enabled in the next few weeks.
Q. How can Office 365 customers connect to custom data sources?
A. Every Office 365-licensed user of PowerApps and Microsoft Flow can create a custom API data connection, in addition to the intrinsic ability to connect to sources like SQL, Exchange, Yammer, Box and Twitter.
Q. How is user access managed/licensed?
A. Flow and PowerApps are managed separately. Here is documentation on how users are managed for Microsoft Flow. Here is documentation on how users are managed for Microsoft PowerApps. They are both quite similar in implementation, and provide options to help prevent existing users from joining an Office 365 tenant.
