Cloudscape III – Driving Europe’s Cloud computing Strategy – took place on the 15 and 16 of March in Brussels offering the perfect opportunity for experts, developers and end-users in the cloud computing space to become part of the cloud standards process. The event, hosted by the EC-funded SIENA initiative, brought a 360° overview on the Cloud computing landscape, covering benefits for enterprise, research and government alongside challenges spanning scalability, data movement, ownership and privacy, security and legal issues, openness and interoperability.

The SIENA initiative presented its document SIENA European Roadmap on Grid and Cloud Standards for e-Science and Beyond. This document addresses requirements, technologies, and interoperability and standards for e-infrastructure to support existing, ongoing, and future research in the European Research Area. The document includes use cases and position papers collected for the Cloudscape III  event. Many of these use cases refer to OpenNebula as core component in their architecture and as a reference open cloud stack to enable interoperable enterprise class cloud computing platforms. Our presentation in this strategic event described the position of OpenNebula on interoperability and standards for cloud computing.
