Cloud computing providers lease resources on pay-per-use basis
but do not expose infrastructure details to customers or partners
Cloud computing consumers use leased resources without
exposing details of their applications to providers
Given the hosting nature of cloud computing providers, consumers
need mechanisms and warranties that their application are
isolated from others that are being hosted in the same
infrastructure
Cloud computing providers should automatically adjust the
resources allocated to a particular application according to
“elasticity rules” provided by cloud computing consumer
To overcome the finite amount of resources available locally, cloud
computing providers should be able to collaborate among
themselves and share their resources

4. CloudWave: Agile Service Engineering for
the Future Internet
Goal
CloudWavewill 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.
Innovations
Technologically, CloudWave will advance the state-of-art along
three dimensions:·
ExecutionAnalytics: A new framework where specialized algorithms
dynamically analyse cloud infrastructure and application behaviour,
seamlessly integrate data pertaining to physical and virtualre sources and IoT
elements, and provide consolidated feedback to drive service evolution and
adaptation·
CoordinatedAdaptation: A new software technology where cloud services,
cloud infrastructure and enduser 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-DrivenDevelopment: A new agile approach for developing
cloud applications, where developers exploit Execution Analytics to
incrementally determine and evolve application feature, extensions and
optimizations, based on observed user needs

5. VISION Cloud: Virtualized Storage
Services Foundation for the Future Internet
Goal
Architect and implement an infrastructure for the reliable and effective
delivery of data-intensive storage services, facilitating the convergence
of ICT, media and telecommunications
Innovations
Raise Abstraction Level of Storage: objects with user- and systemdefined metadata
Computational Storage: technology for specifying/executing
computations close to storage
Content-Centric Storage: facilitate access to data by content and its
relationships
Advanced Capabilities for Cloud-based Storage: support delivery of
data-intensive services securely, at the desired QoS, at competitive costs
Data Mobility and Federation: enable comprehensive data migration
and interoperability across remote locations
