Take a look at this Wrox book as it is structured specifically for beginners. It’s chalk full of wonderful dev resources and examples to follow. Hands down this is the best book I’ve found so far.
As I continue my journey in SharePoint 2013 on-premise and Office 365, this book will be my bible moving forward.
Check out Chapter 5 as it desribes exactly what the cloud is. I love its simplity, but yet technical overview. If your eager to begin accessing line of business date, dive into Business Connectivity Services in Chapter 13. This will help you to understand how to build app-level external types in OData.
Hats off to the Wrox Programmer to Programmer, Steve Fox, Chris Johson, Donovan Follette, and Andrew Connell.
