Heh. I'm happy to let other people try this out - iCloud hasn't exactly had the best record for uptime and little things like this reinforce my worry that Apple doesn't do backend services well.
iCloud has better uptime than Amazon Web Services.
People bash Apple and iCloud and claim they can't do backend software, but they ignore that iTunes has been trooping for over a decade under tremendous load without a pickup. Contrast that with another store on the web- Amazon.com-- which was (at the time I worked for Amazon) generally partially down %40 of the time. (Though not all of it and it does a good job of faking it when it is down.)
Look at AWS where companies like Netflix and Heroku have had days of outages because the AWS network went down or whole datacenters were taken offline.
I've never seen that kind of an outage in iMessages or iCloud.
Apple just keeps trooping not making any noise because it's always working... but because Apple's business model is selling hardware, and people give Amazon a free pass for some reason (I mean why is AWS popular when it's down all the time while Google is rock solid with its hosting services yet less popular?)
iTunes is a specific Apple service, not a platform upon which 3rd party services run. It's one thing to run a product; it's another to run a platform. As a provisioner of PaaS, Apple are not seen as proven.
As for AWS, they're almost ubiquitous. Half the world seems to run on AWS. Regions go down time to time, but half the point of AWS is that it's a distributed architecture that allows apps running on that platform to stay up - usually. Extreme examples (such as dependent PaaS Heroku being taken down) are the edge cases that make it to the press.
It seems like you're only claiming Apple's services to have higher up times than Amazon's because you were able to look at Amazon's up times more closely. Who is to say that Apple's services don't also often have partial downtimes and "faking it when it is down?"
If I'm reading correctly, that means I can build an app without any explicit auth on OS X/iOS with backend which allows access to personal data via AppleID username/password.
This is great for some people, certainly. I won't knock it for people who's lives are better with this.
But let's not kid ourselves. It's still their system; you're still playing by their rules and doing things their way. Their history in this space is not good at all. Maybe things have changed for the better; but it doesn't change the fact that this only brings you deeper into their walled garden.
One of the reasons apple doesn't like the web is they can't make money from them like they can from apps. Now, they have a way. They still have a bad track record with infrastructure; numerous instances of failures, but I imagine they're getting better.
I absolutely don't understand why you got downvoted because i absolutely feel the same. Apple has a proven record of not understanding anything related to the web, and having product and technology issues with anything related to it.
Just yesterday evening, you couldn't add an app on itunesconnect because of some angularjs error ( which they apparently used to refactor their site), and you could trace the debug log on the console, and follow the link on angularjs documentation ( a "bindonce" directive not included error).
They have been providing rock solid internet infrastructure, and the tools for it, going back to the acquisition of NeXT. WebOBjects, for instance, powered Dell's online store, and selling direct was Dell's entire purpose of being in business in the 1990s. It's been powering iTunes since 2003 or so with less than a tenth as much downtime as Amazon Web Services... yet lots of people use AWS.
Yeah I heard that Apple considered buying Parse before deciding to build CloudKit instead. It's a direct competitor, although Parse is still much further ahead. CloudKit is a lot cheaper though.
Correct. You cannot just sign up and get a free 1 PM cloud storage account. The more registered users you have, the more storage space you are allocated. If you go over your allowed storage space you start moving into the paid tier.
Yesterday I'd have said 110%, but I dunno... I'm getting this dreamy feeling that something wonderfully developer-friendly might be going on here. Not to mention owning that infrastructure that let folks also -run- back Android apps seems like it'd have value in itself, beyond just the dev PR.
"Apple is supplying this information to help you plan for the adoption of the technologies and programming interfaces described herein for use on Apple-branded products. "
It doesn't, apparently. The cost seems to be per-user, so
250MB asset storage / user
3MB database storage / user
50MB transfer / user
10 req/s per 100k users
is all free. I don't know how the requests part scales though, 10/s for 100k users is each user hitting it once per 3 hours. I can't complain about the amount given away for free, but I don't know quite how this would scale with costs for different types of apps/loads.
