Hello, I have in my company SharePoint 2016 on premise and would like to use the simultaneous editing option of word, excel and power point. Currently there is the office web apps 2013 and Office online server. I would like to understand the following points:
1 - Office Online Server is a office 365 service that I can connect with my SharePoint 2016 On premise (like an hybrid environment)?
2 - Or should I to install Office Online Server on my company infrastructure in the same way as the OWA 2013?
3 - I have not found any documentation to Office Online Server for sizing and availability issues.
