Hello All,
A book was just recently released titled “Configuring Microsoft SharePoint Hybrid Capabilities” (Download here https://blogs.msdn.microsoft.com/microsoft_press/2016/07/06/free-ebook-configuring-microsoft-sharepoint-hybrid-capabilities/) this is a great read if you want to understand the integration between SharePoint on-prem and the cloud.
As an added bonus one of the authors Manas Biswas is a fellow PFE with an amazing fountain of knowledge, and can often be found providing that knowledge here https://blogs.technet.microsoft.com/beyondsharepoint.
