Here's an anecdote of something that recently happened to me which has some interesting insights into what's currently happening in mobile: During the day I got a call from a friend calling me in my role as a tech- and mobile-savy person. He tells me that he is somewhere in a city because he has an appointment at a certain place with someone he communicated over Facebook. He thought he could remember the address from the top of his head, and, if not, just look it up in Facebook. Wrong on both accounts. Having arrived, the memory of the street number was gone and just in this very instant, Facebook was down as well. Is there anything I could do he asked me?
I quickly checked Facebook and saw that the message stream was also down for me. Nothing you can do I told him, the data you need is in the cloud and won't come out for now. Sorry. So I recommended to go to a street corner café and wait till either the memory or the cloud returns. Eventually, the memory returned. So much relying on online services. Agreed, the exchange of data had to go through the cloud in this case but leaving the critical pieces of information there and then relying on it is a dangerous thing. And that's one reason why I like to have my personal data with me.
IMHO the problem as described above (lack of cloud availability == no access to your data) is not with the “cloud” per se.
I’d like to point out the fundamental difference between using “the cloud” as “master” vs. “only” source of information.
“Cloud sync” services that only sync information between your devices (e.g. Dropbox, iCloud and even Google sync via Exchange) have the advantage that the information is *on all your device(s)* at any time (security matters aside). Of course, if the sync engine or DB gets corrupted, you may loose data anyway.
On the other hand, “Cloud only” services with the single purpose of delivering data in real time (e.g. Facebook stream, Twitter, Google+) depend more heavily on the availability of access (mobile broadband, server uptime).
True Words Christian…
Anyway i’m surprised to see that Martin is on Facebook! I wouldn’t have thought so.. 😉
