Federation of Cloud Computing to Create a Uniform e-infrastructure for Research by Dr. David Wallom

Biography of the presenter

David Wallom is the Associate Director - Innovation at the Oxford e-Research Centre in the University of Oxford. He leads three separate activities within the centre, Energy and Environmental ICT, Volunteer Computing and advanced e-infrasructure including Cloud. He also leads engagement activities within the centre with industry. Following a period as the Technical Director of the UK NGS David has lead the EGI Federated Cloud activity snce its inception as one of the original architects.

Talk Abstract

The EGI Federated Cloud is Europes largest activity in the creation of a federation of heterogeneous public and private sector suitable for use by the research community. The service has been under development since Q4 2011 and was launched into production in May of this year. The FedCloud gives members of all user communities open access to reliable cloud computing resources, an alternative to large multinational providers. As the federation is made up of smaller providers, the service that we offer must include mechanisms where users can easily migrate from one service provider to another, a feature definitely not available in public cloud currently. To enable this we have built from day one with the principles of the usage of open standards where possible and published best practices in other areas.

Invited Talks

Challenges of Multi-Clouds by Dr. Dana Petcu

Biography of the presenter

Dana Petcu (Mrs., PhD) is Professor at Computer Science Department of West University of Timisoara, scientific manager of its supercomputing center, and CEO of the research spin-off Institute e-Austria Timisoara. Her interest in distributed and parallel computing is reflected in more than two hundred papers about Cloud, Grid, Cluster or HPC computing. She was is and was involved in several projects funded by European Commission and other research funding agencies, as coordinator, scientific coordinator, or local team leader. She is chief editor of the open-access journal Scalable Computing: Practice and Experience.

Talk Abstract

The Cloud heterogeneity is manifested today in the set of interfaces of the services from different Clouds, in the set of services from the same provider, in the software or hardware stacks, in the terms of performance or user quality of experience. This heterogeneity is favoring the Cloud service providers allowing them to be competitive in a very dynamic market especially by exposing unique solutions. However such heterogeneity is hindering the interoperability between these services, the portability of the applications consuming the services, the seamless migration of legacy applications towards Cloud environments, as well as the automation of Cloud application deployments.

Various solutions to overcome the Cloud heterogeneity have been investigated in the last half decade, starting from the definition of uniform interfaces (defining the communalities, but loosing the specificities) and arriving to domain specific languages (allowing to conceive applications at a Cloud-agnostic level, but introducing a high overhead).

We discuss the existing approaches and their completeness from the perspective of building support systems for Multi-Clouds, identifying the gaps and potential solutions. Concrete examples are taken from recent experiments in developing a particular Multi-Cloud support system in the frame of MODAClouds project (

(r)OCCI -- Lessons in practical interoperability for IaaS clouds by Boris Parak

Biography of the presenter

Boris Parák is the lead developer in the rOCCI project with numerous major commits and principal author of the rOCCI-server and rOCCI-cli. He is also a system administrator and a member of the team responsible for designing, building, developing and maintaining CESNET’s private HPC cloud — MetaCloud, as well as a member of the EGI Federated Cloud on behalf of CESNET, currently acting as the task leader for Virtual Machine Management.

CESNET (Czech Education and Scientific Network provider) offers long-term experience in cloud and hybrid grid/cloud solutions through NGI activities and participates in the EGI Federated Cloud Task as a resource and technology provider contributing an infrastructure based on OpenNebula exposing an OGF OCCI service endpoint provided by rOCCI-server. It also runs its own private experimental HPC cloud infrastructure based on OpenNebula.

Talk Abstract

OGF OCCI (Open Cloud Computing Interface ) [1] is an open standard/protocol for management tasks in the cloud environment focused on integration, portability and interoperability with a high degree of extensibility. It is designed to bridge differences between various cloud management platforms and provide common ground for users and developers alike.

The rOCCI framework [2][3][4][5] is designed to simplify the implementation of the OCCI 1.1 protocol in Ruby and provide the base for a working client and server implementation targeting multiple cloud management frameworks and commercial service providers via its back-ends. It was adopted by the EGI Federated Cloud [6] and chosen to act as one of the designated OCCI implementations. This led to further development and provided much needed practical experience in real-world conditions.

This talk aims to provide information about the OGF OCCI standard/protocol, introduce its basic concepts and available implementations, describe functionality provided by the rOCCI framework in concert with multiple cloud management frameworks. It also briefly examines the use of OGF OCCI and rOCCI in the EGI FedCloud environment and explores the possibility of further integration, extensions and improvements with interoperability in mind.
