From Distributed to Complete Computing

The HOLA Cloud Roadmap


The HOLA Cloud roadmap compiles the opinion of ICT experts to assess how CLOUD Computing will develop over the next years. Basing on the experts’ opinions the roadmap tries to identify which long-term developments are needed on basis of the overall research and development trends both in industry and academy, as well as market trends that indicate how the requirements and market needs will develop.

On the following pages, the key topics and the individual aspects of the roadmap are presented in full detail and opened to discussion. In regular intervals, the comments will be analysed and the roadmap updated accordingly.

Overview Over the Key Topics of the Roadmap

The major challenges identified by the community and requiring R&I activity to improve CLOUD Computing and to move beyond conventional CLOUD Computing between now and 2030 are:

It was agreed that core to all key topics is the abstraction of code, data and non-functional requirements, i.e. Intention, Information and Incentive. These factors are strongly correlated and interdependent, i.e. incentive influences intention (short: I3). This follows the typical historical drive of IT development towards more abstraction:

  • Information: IT is not so much about data, but about information and knowledge. Interoperability can be achieved by abstracting from data and maintaining what information actually needs to be conveyed. This is a move from compute- to data- to information-centric computing
  • Incentive: Software (and hardware) needs to meet the functional and non-functional requirements, but they need to be “naturally” and understandably defined not as low level concrete service level objectives. Low-level definitions cannot be (de)composed and suffer from application to different contexts.
  • Intention: Every software has a goal, the algorithm is just one path towards that goal. In order to be adaptable, decomposable and freely movable, the intention must be released from one fixed execution, i.e. algorithm.

The following table represents the relationship between I3 concepts and the key sub-topics identified. Note that there is an obvious agreement that all levels of future IT must be incentive driven and that code and data becomes volatile over the mesh of resources that constitute the internet. It will also be noted that the three I are strongly correlated and interdependent (the same sub-topic in more than one column).
