This document discusses using PowerApps and Flow to build a service desk application. PowerApps allows building business apps visually without coding that connect to over 200 data sources. Flow enables automating workflows between apps and services. A demo shows a PowerApp connecting to a SharePoint list for a service desk, with options to build customized SharePoint forms or standalone mobile apps. Flow can automate business processes using triggers and actions. The On-Premises Data Gateway allows PowerApps and Flow to connect to on-prem data.
