CloudWave will revolutionise modern cloud infrastructures and tools by enabling agile development and delivery of adaptive cloud services which dynamically adjust to changes in their environment so as to optimise service quality and resource utilization. In doing so, CloudWave will advance the competitiveness of the EU economy by providing a powerful foundation, based on open standards, for creating innovative cloud services, realising the full promise of cloud computing.CloudWave will tangibly deliver (1) an open architecture and standards-based reference implementation of an advanced cloud software stack, with novel capabilities for adaptation across all cloud layers; and (2) tools and methods for agile development of reliable and adaptable cloud services, facilitated by the new stack.Technologically, CloudWave will advance the state-of-art along three dimensions:· Execution Analytics: A new framework where specialised algorithms dynamically analyse cloud infrastructure and application behaviour, seamlessly integrate data pertaining to physical and virtual resources and IoT elements, and provide consolidated feedback to drive service evolution and adaptation· Coordinated Adaptation: A new software technology where cloud services, cloud infrastructure and end-user devices exploit Execution Analytics to collaboratively and automatically undertake complex adaptation actions across the cloud stack, ensuring quality of service and effective utilization of ICT resources· Feedback-Driven Development: A new agile approach for developing cloud applications, where developers exploit Execution Analytics to incrementally determine and evolve application features, extensions and optimizations, based on observed user needs.Using two industry case studies, we will demonstrate how the CloudWave technology supports emerging cloud services and provides high and quantifiable improvements in service delivery quality, productivity, reliability and cost.
