ProjectShortDescription The goal of the Contrail Project is to design, implement, evaluate and promote an open source system for Cloud Federations. Contrail will leverage and extend the results from the XtreemOS FP6 IP project, which builds a Linux-based operating system to support Virtual Organizations for next-generation Grids. {style:type=span|font-size=14px}Contrail is a complete Cloud platform which integrates a full Infrastructure-as-a-Service and Platform-as-a-Service facilities. {style}{style:type=span|font-size=14px}It allows Cloud providers to seamlessly integrate resources from other Clouds with their own infrastructure, and breaks the current customer lock-in situation by allowing live application migration from one cloud to another{style}
projectOverviewDescription Supply of, and demand for computational capacity is elastic. Some companies are are falling short, others have capacity in abundance. More often than not the need or surplus in computational power or storage capacity is temporary. Wouldn't it be wonderful if the surplus of one corporation could (temporarily) alleviate the wantage of the other? A consortium of ten organisations from six European countries started on a collaborative project to enable just that. The Contrail project aims to design, implement, evaluate and promote an open source computational cloud wherein users can limitlessy share resources. Contrail will vertically integrate an open-source distributed operating system for autonomous resource management in Infrastructure-as-a-Service environments, and high level services and runtime environments as foundations for Platform-as-a-Service. The main achievement will be a tightly integrated software stack in open source including a comprehensive set of system, runtime and high level services providing standardized interfaces for supporting cooperation and resource sharing over Cloud federations. Contrail will address key technological challenges in existing commercial and academic Clouds: the lack of standardized rich and stable interfaces; limited trust from customers; and relatively poor Quality of Service (QoS) guarantees regarding the performance and availability of Cloud resources. Addressing these important issues is fundamental to support large user communities formed of individual citizens and/or organizations relying on Cloud resources for their mission-critical applications. The main contribution of CONTRAIL is an integrated approach to virtualization, offering Infrastructure-as-a- Service, services for IaaS Cloud Federation, and Platform-as-a-Service. It will aim at equalling current commercial Clouds, and surpassing them in a number of selected key domains to facilitate industrial up-take of Federated Cloud computing. The expected outputs of CONTRAIL are as follows:

A collection of infrastructure services offering network, computation and storage as a service:

* Virtualinfrastructurenetworks(VIN)basedonself-organizingoverlaysfornetwork-controlleddata; * Virtual cluster platforms (VCP) managing computation resources; and * Management of federation policies such as security and resource sharing policies; * SLA management at federation and node level for different resource types; and * Autonomic resource management through monitoring and accounting.

A collection of PaaS services to support typical Cloud applications: – High-throughput elastic structured storage;

* Automatic set-up and configuration of SQL servers within the Cloud; and * Geographically distributed key/value store.

A collection of run-time environments providing elasticity, scalability and performance dependability to selected classes of applications:

* An efficient map/reduce implementation; * Scalable hosting for service-oriented applications; and * Autonomic workflow execution.

A collection of applications from the domains of e-business, e-science, telecommunication and media using and demonstrating the advantages of the CONTRAIL open-source system:

* Distributed Provision of Geo-referentiated Data; * Multimedia Processing Service Marketplace; * Clouds for High Performance Real-Time Scientific Data Analysis; and * Large-scale Code Analysis using Clouds for Open Source software.
