I am close to releasing the Service Cloud Consultant course and am recording the final lectures for it, and already planning updates for it when the Spring '18 release hits in the free developer orgs in a few weeks. Look for a new course announcement soon!
Due to the heavy production schedule, I've only been able to record a couple of videos this past week, which I have uploaded to my YouTube channel - you really should subscribe here.
Helpful resource and diagrams to tell you which objects are in which cloud.
This is relevant to both the Sales Cloud Consultant and Service Cloud Consultant Certification exams.
Happy learning and see you in the cloud!
