http://gitorious.ow2.org/xlcloud
ATEME: H264/MPEG-4/AVC low latency
compression algorithms
Bull: cloud infrastructure, distributed systems
architecture and HPC cluster
CEA List: interactive simulation of natural
phenomenons, virtual reality
EISTI: marketplace, OpenERP integration
Inria Reso: energy efficiency
TSP (Lab Artemis): MPEG standardization, video
compression, multimodality
Silkan: massively distributed (HPC) software
architecture for interactive simulation
OW2: communication, dissemination

4. Slide 4/7
Key Tenets and Objectives
Provide virtual cluster instances on-demand through self-service API and Web UI
Point to point application latency (lag) < 200 ms (pipeline, capture/encode, network, decode,
display)
Standard compliance (Eg. SAML V2, OAuth 2.0, XACML)
Layered and modular design to allow for seamless support of many types of applications
and workloads (purpose-built PaaS computing environment)
Policy-based Service Level Management (SLM) with automatic scale-up / scale-down
Business applications integration framework for service composition and aggregation
Secure multi-tenant environment (isolation, strong authentication and access control)
Adaptation of the Cloud Management System to best leverage the underlying infrastructure
performance (HPC cluster)
Fine-grained resource usage metering and accounting for chargeback
Energy efficient meaning produce the most output for the least cost
