This document summarizes several European cloud computing research projects: 1. Cloud TM aims to develop a novel programming paradigm and middleware to facilitate cloud application development and administration while optimizing efficiency. 2. OpenNebula and Reservoir focus on enabling resource allocation and deployment flexibility through federation and elasticity. 3. ABC4Trust researches attribute-based credentials to improve trust and privacy in credential interchangeability. 4. Optimis, Vision Cloud, and TClouds develop frameworks and toolkits to optimize cloud ecosystems for trust, risk, cost efficiency through areas like storage, data mobility, and security.

3. Cloud TM
http://www.cloudtm.eu/

4. Cloud TM
● Defining a novel programming paradigm to facilitate the
development and administration of cloud application
● Developing a Self-Optimizing Distributed Transactional
Memory middleware
● Spare programmers from the burden of coding for
distribution, persistence and fault-tolerance
● Letting them focus on delivering differentiating business
value
● Aims at minimizing the operational costs of cloud
applications, pursuing optimal efficiency via autonomic
resource provisioning & pervasive self-tuning schemes

6. OpenNebula
Reservoir
● Enable smaller infrastructure providers to collaborate
through the federation of their resources on demand
● Allow automatic allocation and deployment of resources to a
service as demand fluctuates using a concept called
elasticity
● Allows service providers the ability to define both an initial
and maximum allocation of resources
● Automatically monitors the service performance that it is
running, increasing or decreasing allocated resources
behind the scenes to minimize costs
● Allows a greater utilization of physical resources in the
Cloud - translates into lower costs (for infrastructure, service
providers and consumer)

7. ABC4Trust

8. ABC4Trust
Attribute-based Credentials for Trust
● the goal is to address the federation and interchangeability
of technologies that support trustworthy yet privacy-
preserving ABC
● the aim is to deepen the understanding in ABC
technologies, enable their efficient/effective deployment in
practice, and their federation in different domains
● to define a common, unified architecture for ABC systems to
allow comparing their respective features and combining
them on common platforms
● to deliver open reference implementations of selected ABC
systems and deploy them in actual production pilots
allowing provably accredited members of restricted
communities to provide anonymous feedback on their
community or its members

9. Optimis
http://www.optimis-project.eu

10. Optimis
● to identify, capture and codify what an optimized cloud
ecosystem driven by trust, risk, eco-efficiency and cost will
look like
● a framework and toolkit that will simplify service
construction, and support deployment and runtime decisions
based on prior evaluation of providers
● to facilitate the use of resources based on economic and
eco-efficiency goals while achieving a dynamic and
proactive management of cloud infrastructures
● to enable clouds to be composed from multiple services and
resources
● to identify value networks for these cloud markets and
recommend suitable legal and regulatory guidelines for
operation

11. Vision Cloud
http://www.visioncloud.eu/

12. Vision Cloud
● Raising the Abstraction Level of Storage - Encapsulating
storage into objects with user-defined and system-defined
attributes (a.k.a. "metadata")
● Data Mobility and Federation without Boundaries - extend
the limited data migration capabilities available in
contemporary infrastructures to migrate and federate data
across geographically distributed administrative domains,
ensuring comprehensive and transparent data
interoperability and overcoming the problem of data lock-in
● Computational Storage - Providing an architected solution
for bringing computing to storage by enabling secure
execution of computational tasks near their data

13. Vision Cloud
● Content Centric Storage - Facilitating access to data by
content and its relationships rather than details of the
underlying storage containers
● Advanced Capabilities for Cloud-Based Storage -
Combining the base concepts for cloud computing with
additional capabilities of storage virtualization, advancing
the state of the art by creating a platform where data-
intensive services can be provided securely, at the desired
level of service, and at competitive costs

14. TClouds
http://www.tclouds-project.eu

15. TClouds
● aims to build a prototype Internetscale ICT infrastructure
which allows virtualized computing, network, and storage
resources over the Internet to provide scalability and cost-
efficiency
● to identify and address the legal and business implications
and opportunities of a widespread use of infrastructure
clouds, contributing to building a regulatory framework for
enabling resilient and privacy-enhanced cross-border
infrastructure clouds

16. TClouds
● to define an architecture and prototype for securing
infrastructure clouds by providing security enhancements
that can be deployed on top of commodity infrastructure
clouds (as a cloudof-clouds) and assessing the resilience
and privacy benefits of security extensions of existing
clouds
● to provide resilient middleware for adaptive security on the
cloud-of-clouds - the TClouds platform will provide tolerance
and adaptability to mitigate security incidents and unstable
operating conditions for a range of applications running on
such clouds-of-clouds
