SIENA is the first initiative to bring to the same table relevant
standards organisations to support a coordinated development and
implementation in the context of the SIENA Roadmap. The Position Papers collected here for Cloudscape IV (23-24 February 2012) provide
related insights into a fast-evolving landscape. A wide variety of
views and perspectives are given. The first section focuses mainly on
the evolution of e-infrastructures in response to both new user
requirements and the arrival of new technologies as a sign of vigorous
health alongside the broader European landscape. A sample of current
trends and challenges for cloud-based public services in Europe is
provided together with international perspectives. The last sections are
dedicated to challenges surrounding trust, security, legal and data
issues and examples of current standardisation work aimed at responding
to community-driven challenges.
Cloud computing is moving at an incredibly fast pace. We use cloud services every day for internet searches, mobile applications, photo sharing, messaging, and social networking. The internet of things is expected to drive many new applications in the cloud. In the scientific arena, cloud computing is gaining momentum for data intensive problems because they have the closely coupled structure well supported in clouds. Cloud computing is also seen as a great potential for mitigating financial and other difficulties of public administrations in Europe. It promises not only the optimised usage of IT resources, but also implies a great variety of collaboration and consolidation options.
International standardisation efforts are expected to have a huge impact on cloud computing. However, several major governmental cloud computing programmes are being pursued in the absence of an adequate set of agreed and accepted open standards that could guarantee security, portability and interoperability of cloud services. It is imperative that the current standardisation dialogue is intensified and extended to involve all stakeholders spanning standards organizations, cloud cooperative working groups, open-source and commercial providers, global and regional public sector institutions. Only a continuous open dialogue on priority actions will help us unleash the full potential of cloud computing arena for the collective common good, globally.
