I don’t know, I’ve never been the fan of the put everything in the browser and “fly me to the clouds” movement, for several reasons. First, in my opinion the web browser is called browser and not “advanced data manipulation and browsing and knitting interface” for a reason.

The second is that well, if you put everything in the cloud, what do you do when it starts to rain? Dare Obasanjo certainly has a point that a 99.9% uptime means almost 9 hours of downtime a year. Some posts are not really using the same math as I do, they calculate with a worse service level, and that completely undermines the complaint (99% uptime means almost 88 hours of downtime a year, so 6 hours is not that bad). And if you are here, go and read Om Malik’s opinion, he has a long post on the topic.

So, Amazon is promising almost 9 hours of downtime. If that 9 hours happen to arrive on a quiet Sunday – or over several quiet Sundays – then it’s no problem really.

But what do you do if that 9 hours drive accross the last day of a critical project phase?
I like the idea of cloud computing, and I don’t want to say that you should not use Amazon S3, or Zoho or GoogleDoc, or whatever service you are using. I just would like to know what will happen to your service when the cloud gets dark?

On LinkedIn there was a question on why people want technical documentation in PDF, on paper, in Word, when all information can be put on internal wikis, blogs, etc. Most of the answers pointed to the neccessity to reach the things offline.

And not only when the server goes down. Interesting thing I read on JibberJobber, LinkedIn for example does not have a backup of your profile. If it disappears for whatever reason, you are toast. Have to start from scratch. That’s a good reason to save all your contacts, and your profile on your PC regularly – i.e. whenever there is a change.

Internet access is not 100% around the world, and the internet does not have 100% uptime. Bits go down regularly. I bet there are a couple intranets down even right now. Also there are 3 things in life that are certain: death, taxes and data loss.

I don’t talk against cloud computing – who am I to talk against it anyway -, I just want to point out that when you go near the clouds, you better have an umbrella, just in case.
