Cloud, Cloud, Cloud. Everywhere you look, someone is talking about "The Cloud." Check out the Google Trends chart below. I'm pretty sure Cloud computing is not a fad, but if you're like me, you're: excited, confused and a bit skeptical.
The news volume for 'SaaS' (think SalesForce.com) has had a nice slow ascent since 2004. But the trend line for 'Cloud Computing' is explosive, beginning in late 2007 (around the time Amazon's EC2 Cloud graduated from Beta). 'Cloud Computing' starts with a rapid take off and keeps going. With a rapid ascent like this, it's either a short lived fad or a long-term trend that starts with a lot of hype.
A quick tour through history can help you understand how we got here. In 2005 (yes, only five short years ago), Sun launched a brilliant marketing campaign around 'Utility Computing' which promoted a $1-per-hour-per-CPU pay-per-use model. (You can listen to Jonathan Schwartz, Sun's CEO at the time, talk about it.)
Unfortunately, Sun's target wasn't just any enterprise who wanted to run their software on the Cloud, but rather big financial services companies that required lots of computing power for a limited amount of time for things like Monte Carlo simulations. That's probably why they called it a 'Grid' and not a 'Cloud.'
Soon after, the big bad Internet retailer Amazon launched a preview of their "Elastic Cloud," or EC2 and Amazon had a very different model from Sun. They opened up their infrastructure to anyone who wanted to run their software on it. The catch was you had to do all the setup yourself and all you really had to work with was a Linux AMI on a small/medium/large box. There wasn't even a persistent file system at the time, so you had to do a lot of work to run a web application that actually saved data.
But even with these limitations there was something very liberating about getting an EC2 account and starting an instance with whatever version of Linux you wanted, all for a small per-hour fee. You could shut down your instances at any time and pay nothing until you started them up again.
Within the next few years Amazon added all the bells and whistles: lots of AMIs, lots of machine configurations, persistent file systems, a load balancer that manages health, geographic separation, SLAs and even a database as a service. It was this simple cost model in combination with a sophisticated platform that motivated my company to put our enterprise mashup platform, Presto, on EC2 last month. We call it the Presto Cloud Community Edition and all 4,000 of our mashup developer community members use it.
I love telling the story about how easy it was to get running. It took less than 30 minutes to get an instance of our software platform running on the Cloud. Yes, it took a bit longer to 'teach' EC2 how to get it running in high-availability (HA) mode. But now that we have that working as well, we simply save out the AMIs and just start them when we need them. Instant cloud-based HA!
Once you realize that YOU can have an infinitely scalable, highly available, collaborative platform for a fraction of the price it would cost you in your own datacenter, you start to realize the power of the Cloud. Maybe the hype is actually worth listening to this time.
If you need a community-driven system, then, you can go with public Cloud. Otherwise, i.e. if your system is business-driven (like in finance, telecommunication, healthcare, etc.) the maximum you may allow is using of private Cloud. Ces't la business vie.
What we talked about in mid-1990 there was a system where the address book an individual company - and the visionaries even personal directory - could somehow plug into "the world, and they all show the same level of ' index. The benefits of having all this information a day (always available) and global (available everywhere) system seemed enormous. I still am. But technology was not there - and really was the beginning. So the time it seemed that those of us who want to Landmark Federal directory model much lower. One of them, who had spoken, that the federal model back in mid-1990 was Microsoft's Kim Cameron. Cameron and never lost sight of that vision. He said recently that the time might be right to start developing a system that many of us had imagined oh so many years ago.

But technology was not there - and it was really the beginning. Thus, over time, it seemed that those of us who want to model Landmark federal library is much smaller.
Interesting reading this article retrospectively after witnessing the 'cloud' changes since its publication!!
Interesting post, pretty much covered it all for me, thanks.
