Review: Traditional Developer vs Cloud Developer

Another interesting article.

I need to do more research on the argument made in this article about the need to become a Cloud Developer. There will just be too much technology to learn if we keep thinking that a techie needs to learn stack development, deployment, tech support, translation of business domain knowledge into technical feasibility, and more.

Teams will continue to grow and not with an all-in-one talented techie. Developers will continue to need to specialize, in my opinion. But, if the cloud handles all the deployment and support issues, then maybe a developer can just focus on - developing?
