Is Azure WebDeploy safe for production Web Apps? We use Azure Web Apps in production. We deploy using WebDeploy either by right-clicking the project in Visual Studio and choosing "Publish..." or via CI in AppVeyor, which is WebDeploy ready.

My question is: Is WebDeploy safe for production environments? Will it interrupt running processes, or does it work some magic to make sure it doesn't? Can we publish to production using WebDeploy during business hours (when our customers are active) and not worry about it? A good answer will provide some documentation on this, as I have not been able to find this yet.
WebDeploy by itself cannot guarantee if your application pool will not be recycled during deployment. To be on the safe side, I would use deployment slots. 
Also I would recommend to tag question with azure-web-sites so right people will help you.
