Apple iCloud - Can somebody explain

Question

So is Apple iCloud a competitor for other data storage frameworks such as Core Data?

To be honest I'm not entirely sure how it works. I am currently building an app and was going to use a database to store and load data, but am I right in thinking that iCloud could be used in such a way, to act as a database?

Answer 1

On the other hand, if you use Core Data, iCloud can potentially sync your data across devices...

...And now that we're past the NDA period, see iCloud document here... (look for Using iCloud in Conjunction with Databases) and the release notes here:

Answer 2

Most iCloud developer information is still under NDA, so we can't discuss it deeply here, but based just on the public information, iCloud is not a database and so does not really intersect with Core Data. iCloud is a way to sync documents.

Answer 3

Watch the last keynote, Steve Jobs explains iCloud pretty well.
