If I had to convince a non technical person about Cloud Computing, I would show him this video.

I really enjoyed listening to Dr. Werner Vogels. Dr. Vogels is Vice President & Chief Technology Officer at Amazon.com where he is responsible for driving the company’s technology vision, which is to continuously enhance the innovation on behalf of Amazon’s customers at a global scale.
This vision is why I have moved to EC2/S3 in 2007. I guess, I’ve finally become an Amazon AWS fan boy.

Even if audio is a bit out of sync, it’s worth to listening this long session.
As a developer from the bottom of my heart I like especially this quote: “There is no value in being a system administrator. You do not build a better product by being a better server maintainer.” This is so true, but I wonder how EC2 can free me from typical administration tasks. I still have to maintain my virtual server instances with the whole LAMP stack. Plus I have to think about how to scale horizontally (what to do when I need more virtual server instances).
In contradiction to Amzon’s EC2, Google’s AppEngine promises to free me from doing the admin tasks (no OS/LAMP Stack to maintain) and to solve the scale problem (no Database Replication to set up). AppEngine scales out of the box – the downside is, that it offers a very limited runtime just for you app.
True, a single EC2 instance doesn’t scale out of the box but it also doesn’t limit you in doing what you want to do on your virtual server. With EC2 I have to solve the scaling on my own. For this price I got more freedom.
I’m exited to use and learn about EC2/S3/Storefront each day but I also hope that Google’s AppEngine will offer a wider range of runtime environments in the future. t’s an interesting Cloud-Year 2009! #buzzword
