New Software Engineering Requirements in Clouds and Large-Scale Systems

The primary IT paradigm has changed from a compute-centric to a data-centric problem perspective. For decades our whole IT concepts were building around the foundation laid out by von Neumann. As the memory wall, parallelism, dynamicity, and multitenancy become the predominating factors in modern application performance and capabilities, this foundation doesn´t hold true anymore. Rather than building up new layers, a complete rethinking of the software engineering principles is in order to overcome the essential issues in the long run. This article provides an overview over the core problems and the different approaches to overcome them.
