Actually, one could say, it is being changed in several dimensions.
Think about security which appeared to be something for the experts, and nowadays reshapes the way we think about software. And some of the thoughts around security today may involve user behaviour as an additional way to authenticate us. Wow! Nice. Although it does also imply user behaviour is something you need to consider.
Well, you may think "but there is a lot of data that now needs to be processed for that", and "what about the structure of such data?" Well, have you seen all the developments around big data and high performing databases which the cloud is enabling? Ok, I give it to you… but then how can I, as a developer, make use of that data? Well, API’s is the answer. An old and beautiful concept that is being embedded in software development now, as collaboration with others is a must. Your software needs to be easy to interface with and as such it must provide a clear and easy API for others to use. Better even is the fact that software in the cloud must have API’s, becoming a de facto standard otherwise you are out. (By the simple fact that adoption will be hard if not impossible with all the competition around.)
The more common areas where the cloud appear initially to have impact was on whether the application was executed on bare-metal or on a virtualized environment reshaping componentizing the hardware and the different layers of software. This too, is something that affects application development as we need to think also on those components/containers we can use/enable others to use. Consider frameworks for it and make the necessary provisions in your application architecture.
Also of utmost interest were the innovation presentations that took place on a plenary/breakout, or campground sessions. It was amazing to see how creativity is being applied to develop the technological step around the cloud; think about natural language support API, and its applicability on the artificial intelligence spectrum, which nowadays is within our reach, it is in our hands (literally) with our phones/tablets.
