I like best how easy it was to set up, configure permissions for users/groups etc., as well as deploy apps in our cloud environment (AWS). The ability of being able pull all your app definitions into one place makes life easier too! There's not much we don't love about this product but would be nice if there were more options when using custom domains with Appsilue - e.g.: 1) Allow domain owners or admins full control over DNS records2.) Ability to have email notification sent via SES rather than having emails bounce back3.).
