I discovered these articles out there today comparing the IBM and Oracle cloud solutions (I also added these articles to our community bookmarks). They are quick and easy reads - written by Roman Kharkovski. I think they provide a good overview and can help answer a number of questions many people may be wondering about how IBM solutions compare to those from Oracle. You can also click on Roman's name at the header of each article to see other articles in this series that he has written.
