Configuring SharePoint hybrid features can be a daunting task and require a lot of planning and testing at every step along the way, but the results are well worth the effort. We have seen how configuring hybrid search allows us to extend our on-premises SharePoint environment into the cloud by making it easy to locate files regardless of their location. We have seen how we can expand our storage requirements without having to invest in new hardware or software by using OneDrive for Business hybrid and redirecting local users to SharePoint Online to access their personal files. Finally, we briefly looked at an example of using BCS, which allows us to securely publish sensitive data to external users.
Just remember that it's not just about implementing these features successfully, it's also about giving our users the best training possible so they can make use of them. This in turn results in more efficiency and productivity, and ultimately less calls to your helpdesk!
