Noob question. What are the implications of writing books on platforms that are commercial in nature? Say I want to write a book or apigee or IBM bluemix. Are there licensing restrictions on what I can cover and what not.
To your specific question the vendor's EULA may have language that puts in restrictions (e.g. most restrict benchmarks). So, give the EULA a close read to get a sense. Second issue that you will have to pay attention to is trademarks, you'll need to seek some guidance so as to not put you on the wrong side of trademark law.
