Text in French below

There is a global trend towards outsourcing computing services to third party providers via the World Wide Web. Since such “Cloud Services” can be more cost-effective than hosting those on-premises, it can be in CERN’s interest to use them. However, certain aspects of the Cloud Services' “Acceptable Use Policy” related to privacy, data protection & ownership, security need to be carefully assessed and data locality must comply with CERN’s privileges and immunities.

The Cloud Licence Office (CLO) has been established to provide guidance on the purchase and use of cloud services by members of CERN’s personnel, evaluate whether adverse conditions exist and whether the overall risks are acceptable to the Organization, and to authorize any site-wide purchase & usage of Cloud Services.

The CLO works in close contact and in cooperation with the Procurement and Industrial Services group (IPT-PI), the IT Consulting Team and the Software Licence Office (SLO). If needed it liaises with the Computer Security Officer (CSO), the Office of Data Privacy Protection (ODPP) and with the Legal Service.

The CLO operates on the basis of a Policy for Cloud Usage. As per this policy, each of the two categories below is linked with specific obligations:

• Entreprise Clouds: Require a contract with CERN following previous consultation and approval by the CLO. For this case, please collect the information and documents described in Questions to Enterprise Cloud providers before contacting the CLO.
• Public Clouds: They can be used by individuals without conclusion of a contract with the service provider if the following criteria are met: no CERN legally protected data involved, confidential data restrictions strictly adhered to with appropriate access controls, and possibility to transfer all CERN data onsite or to another account when required. The usage of public clouds is allowed provided the service is registered in the list of certified public clouds maintained by the CLO. To be added to such list a public cloud must have satisfactorily completed the CERN Self-assessment of Public Clouds.

Mise en œuvre de la politique d’informatique en nuage du CERN

Il y a une tendance générale à l'externalisation des services informatiques à des fournisseurs tiers via le World Wide Web. Faire appel aux services de fournisseurs de nuages (cloud services) peut en effet s’avérer plus économique que l'hébergement sur site, ce qui peut présenter un certain intérêt pour le CERN. Toutefois, certains aspects de la « politique d'utilisation acceptable » des services en nuages liés à la confidentialité, à la protection et à la propriété des données, et à la sécurité doivent être soigneusement évalués, et la localisation des données se doit d’être conforme aux privilèges et immunités du CERN.

Le bureau des licences de services informatiques en nuages (Cloud Licence Office, CLO) a été créé pour prodiguer des conseils sur l'achat et l'utilisation des services en nuages par les membres du personnel du CERN : il évalue si certaines conditions sont défavorables et si les risques globaux sont acceptables pour l'Organisation, et autorise l’achat et l’utilisation de ces services à l’échelle de l’Organisation.

Le CLO travaille en étroite collaboration avec le groupe Achats et services industriels (IPT-PI), l'équipe de consultants en informatique et le bureau des licences logicielles (SLO). Au besoin, il assure la liaison avec le responsable de la sécurité informatique (CSO), le bureau de protection des données personnelles (ODPP) et le service juridique.

Le CLO fonctionne sur la base de la politique pour l’utilisation de l’informatique en nuage. Conformément à cette politique, chacune des deux catégories ci-dessous doit répondre à des obligations spécifiques :

• Nuages d'entreprise : ils nécessitent l’établissement d’un contrat avec le CERN à la suite d'une consultation préalable et de l'approbation du CLO. Dans ce cas, veuillez consulter les informations et les documents disponibles sur la page « Questions to Enterprise Cloud providers » (en anglais) avant de contacter le CLO.
• Nuages ​​publics : ils peuvent être utilisés sans l’établissement d'un contrat avec le fournisseur de services si les critères suivants sont respectés : les données protégées par le CERN ne sont pas concernées, les restrictions sur les données confidentielles sont strictement respectées, il y a possibilité de rapatrier toutes les données du CERN sur site ou sur un autre compte si nécessaire. L'utilisation de nuages publics est autorisée à condition que le service soit enregistré dans la liste des nuages publics certifiés par le CLO. Pour être ajouté à cette liste, un nuage public doit avoir rempli de manière satisfaisante l'auto-évaluation des nuages ​​publics au CERN (en anglais).

AARNet and CERN (the European Organization for Nuclear Research) recently signed a formal agreement which establishes a framework for ongoing collaborations to develop cloud storage technologies for the benefit of scientific and education communities globally.

Both organisations share interests in enabling new and more efficient ways of collaborating to support international research endeavours, particularly around innovation for data storage, data transfer and data sharing.

For the past two years, AARNet engineers have been collaborating with the CERN IT Storage Group to test distributed deployments of large-scale storage systems. The AARNet network’s capabilities for moving huge volumes of data across Australia’s vast continent is helping to inform research for advancing networking and data services for science.

AARNet and CERN have also been collaborating to promote the creation of a community of cloud-technology adopters to share innovative solutions and operational best practices, co-organising events such as the CS3 (Cloud Services for Synchronisation and Sharing) conferences and workshops.

Under the new agreement, the organisations will work together on developing solutions, such as the AARNet CloudStor service which is building on CERN’s EOS. The CERNBox and SWAN services will also be part of this collaboration.

All these cloud-based services support the management of data storage, access and analysis for a range of users. EOS is a low latency heavy duty data storage infrastructure designed for the data deluge from Large Hadron Collider high energy physics experiments; CERNBox, is a cloud storage service meeting the unique needs of non-high-energy physics CERN users; SWAN, is a platform for performing interactive data analysis in the cloud via a web browser; and CloudStor is a data sharing and service with a wide range of research applications designed to meet the unique needs of the Australian research community.

The IT department will publish soon on the CERN job portal the following Computing Engineer job:

Identity Federation Manager for the Academic Community in the Departmental Infrastructure Group, Computer Security Team (IT-DI-CSO).

With the steadily growing community of HEP institutes collaborating with CERN and contributing to joint projects (like the WLCG; cern.ch/wlcg) but also with the widening of CERN’s computing resources to other sciences (HelixNebula, e.g. CERN as a cloud service provider), the current model of providing every participant with a CERN computing account does not scale anymore. Instead, federated identities, i.e. computing accounts issued by individual universities and institutes themselves, which are subsequently permitted to access CERN’s computing resources are the best alternative currently. However, to embark on such an alternative, tight coordination of the technical implementation and related subjects like trust, vouching, security, data privacy and data dissemination (“attributes”) are necessary. Currently on-going activities in this domain are REFEDS (www.refeds.org), EduGAIN (www.geant.org/Services/Trust_identity_and_security/eduGAIN), AARC (aarc-project.eu), and Sirtfi (refeds.org/sirtfi) to name a few.

You will join

This includes the deployment of the current policies, negotiation and implementation of new policies, and the co-ordination of any (other) aspect which enhances the trust, security, and data privacy principles within the corresponding federations. Close contact with the WLCG will also be beneficial since identity federations have strong similarities to the policy bodies governing the WLCG.

As a Service Manager, you will be in charge of the implementation and integration of the different services and tools to fulfil the practical objectives of Federation: Integration with CERN Single Sign-on, integration of multifactor tokens when available, design and implementation of a new fine-grained authorization service taking into account Federated Identities, WLCG support, etc.

As a member of the Computer Security Team, you are also supposed to participate in the CERN CERT (Computer Emergency Response Team) and contribute to the resolution of computer security incidents.

Résumé

Le CERN peut sans aucun doute être décrit comme l’un des projets scientifiques les plus ambitieux jamais entrepris. Depuis 60 ans, les États membres ont non seulement investi des sommes importantes pour financer une institution, mais aussi un programme de recherche visionnaire. Cela a contribué à changer la façon dont les recherches sont menées, un changement que l’on résume par l’appellation « big science ».

Cependant, cette forme de projets de recherche à grande échelle soulève également un certain nombre de questions fondamentales : que signifie « faire de la recherche » aujourd’hui ? Qu’est-ce qui a changé ? Qu’est-ce qui justifie un tel engagement de la société et un tel soutien pour un projet scientifique si long et si coûteux ? Enfin, de quelle manière les recherches menées au CERN ont contribué, et contribuent encore, au développement de la société contemporaine ?

En se basant sur quelques exemples clés, cette conférence examinera de quelle façon la recherche a changé, et comment les relations entre la science et la société ont évolué depuis la création du CERN. Cela nous permettra de mieux comprendre les multiples liens qui existent entre la recherche et la société contemporaine.

What science for what kind of society? Reflecting the development of big science, by Professor Ulrike Felt

Tuesday 15 July 2014 at 7:30 p.m.

Abstract

Without any doubt, CERN can be described as being among the most ambitious scientific enterprises ever undertaken. For 60 years, the Member States have not only invested considerable financial means into this institution, but have also supported the creation of a highly visionary research programme. And this has led to a change in the way science is done, as captured by the idea of "big science".

Yet this naturally also raises a number of quite fundamental questions: How did the meaning of "doing science" change? What justifies societal engagement with and support for such a cost-intensive long-term scientific undertaking? And finally, in what ways does (and did) this research enterprise contribute to the development of contemporary societies?

By focusing on some key examples, the talk will thus explore how the ways of doing research and scientific and societal relations have undergone change over the history of CERN. This will allow an understanding of the many ways in which the development of research and contemporary societies are intertwined.

Biography 

Ulrike Felt is Professor of Science and Technology Studies, Head of the STS Department and Vice-Dean for Research of the Faculty of Social Sciences at the University of Vienna. She holds a PhD in Physics/Mathematics and a habilitation in Sociology of Science/Science and Technology Studies. Her research interests gravitate around issues of governance, democracy and public participation in technoscience, changing research cultures, and the role of time in science and society issues. She has published widely in these fields. Her work is often comparative between national contexts and between technological or scientific fields (especially life sciences, biomedicine and nanotechnologies). She has been an invited professor at numerous universities and has been involved in policy advice to the European Commission as well as to national bodies. From July 2002 to June 2007 she was editor-in-chief of the international peer-reviewed journal Science, Technology, & Human Values.

Science and society : the impact of computing at CERN on society, by Dr. Bob Jones, CERN IT department

Thursday 22 May 2014 at 7:30 p.m.
Globe of Science and Innovation
Route de Meyrin, 1211 Genève

Lecture in English, with simultaneous interpreting into French

Abstract
CERN is often referred to as the place “where the web was born”. The world-wide-web has fundamentally changed society and launched a wave of new global industries. The world-wide-web happened because there was a specific problem that was seen as an Information Technology (IT) challenge by its inventors. As the scientific programme of CERN has progressed, new IT challenges have been faced such as how to handle the mind-boggling amount of data that is produced by the Large Hadron Collider (LHC). Being able to face those challenges has contributed to the success of the LHC and the discovery of the Higgs particle. This public lecture will explore some of those challenges, how they have been tackled and what impact they are having beyond physics and ultimately on society as a whole.

Biography
Bob Jones is head of the CERN openlab project (openlab.cern.ch) which is a unique public-private partnership between CERN and leading ICT companies. Its mission is to accelerate the development of cutting-edge solutions to be used by the worldwide LHC community.

Bob is a member of the management team of the Helix Nebula – the Science Cloud initiative (http://www.helix-nebula.eu/), a public private partnership to explore the use of commercial cloud services for science applications.

Bob joined CERN in 1986 as a software developer providing support for the physics experiments running on the now dismantled Large Electron Positron (LEP) particle accelerator.   He has been involved in several research projects for the LHC accelerator and has held the position of leader of the online software system for the ATLAS experiment (http://www.atlas.ch/) at the LHC. 

His experience in the distributed computing arena includes mandates as the technical director and then project director of the EGEE projects (2004-2010 http://www.eu-egee.org), which established and operated a production grid facility for e-Science spanning 300 sites across 48 countries for more than 12,000 researchers.

Résumé
On parle souvent du CERN comme le « berceau du web ». Le web a changé notre société en profondeur et a contribué à la création de nouvelles industries globales. Le web a vu le jour parce que ses créateurs avaient un problème précis à résoudre qu’ils ont considéré comme un défi de la technologie de l’information. Le programme scientifique du CERN s'est depuis développé, créant de nouveaux défis tels que la gestion de la montagne de données produites par le Grand collisionneur de hadrons (LHC). La capacité de faire face à ces questions a contribué au succès du LHC et à la découverte de la particule de Higgs. Cette conférence publique abordera certaines de ces questions, la façon dont elles ont été résolues et l’impact qu’elles ont au-delà de la physique, et en fin de compte, sur la société entière.

Curriculum Vitae
Bob Jones est responsable du projet CERN openlab(openlab.cern.ch), un partenariat unique en son genre entre le CERN et des entreprises privées spécialisées dans les technologies de l'information et de la communication.  L’objectif de ce projet est de stimuler le développement de solutions de pointe utiles à la communauté LHC du monde entier.

Bob est aussi membre de la direction du projet Helix Nebula – the Science Cloud (http://www.helix-nebula.eu/), un partenariat public-privé qui explore l’usage de services commerciaux en nuage pour des applications scientifiques.

Bob a rejoint le CERN en 1986 en tant que développeur de logiciels, pour apporter son appui aux expériences de physique menées auprès du Grand accélérateur électron-positon (LEP), aujourd’hui démantelé. Il a également participé à de nombreux projets de recherche pour l’accélérateur LHC et a été responsable du système de logiciels en ligne pour l’expérience ATLAS (http://www.atlas.ch/) du LHC. 

Son expérience en infrastructures de calcul distribuées comprend des mandats  en tant que directeur technique d’abord, puis en tant que directeur, des projets EGEE (Enabling Grids for E-sciencE) qui ont créé et exploité une infrastructure de grille de production couvrant 300 sites dans 48 pays différents, et utilisée par plus 12 000 chercheurs.

Monday 4 June

09:00 Oracle Architecture, Przemyslaw Adam Radowiecki
The objective is to go through Oracle database physical and logical structures, highlighting the consequences of some of Oracle's internal design choices for developers of database applications. The presentation defines Oracle-related basic terms and illustrates them based on the database architecture.
The following topics will be discussed:
• Database with its physical and logical structures (tablespace, segment, extent, block, database user, schema, user's quota)
• Single instance (significant memory structures: buffer cache, shared pool)
• Real Application Cluster (RAC)
• Connecting to the database (TNS, database service)
• SQL statement processing (hard and soft parsing, cursor, cursor sharing, execution plan)

10:00 Database and Application Design, Katarzyna Maria Dziedziniewicz-Wojcik
The primary goal of this presentation is to show how to design a scalable application using Oracle that performs. We will start with schema design that allows storing the data in a way that is efficient, scalable and makes those data easily retrievable. In that part focus will be put on ER model and best practices in schema design. Later we will explain in detail SQL statement processing, with a number of tips/and tricks. The last part will talk about building a robust application using privileges, different connection types and a number of other features.

11:00 Database Security, Szymon Jozef Skorupinski & Daniel Gomez Blanco
During the Database Security Tutorial we will focus on Oracle Database security from the developers' point of view. We'll cover a few topics, including authentication, roles and privileges, auditing, encryption and SQL injection attacks.

Tuesday 5 June

09:00 SQL and Advanced SQL, Marcin Blaszczyk
SQL (Structured Query Language) is a programming language designed for managing data in relational database management systems. The aim of the tutorial is to provide an overview of the SQL language basic capabilities and several selected advanced SQL features available in the Oracle Database Management System. The main part of this tutorial will focus on the use of advanced SQL such as: complex queries, analytical functions, set operators, views and temporary tables, materialized views, indexes and partitioning.

10:30 PL/SQL, Zbigniew Baranowski & Stephan Petit
PL/SQL is Oracle's procedural extension of SQL. In this tutorial we will present the basic concepts behind PL/SQL and the general appearance of a PL/SQL program, covering general structure, control statements and basic units of the PL/SQL language.
We will then focus on best scripting practices -things that each developer should know in order to write efficient code and avoid common traps.

Friday 8 June

09:00 Tuning, Luca Canali & Dawid Wojcik & Eric Grancher
In this session, you will learn how to understand what prevents your application from running as fast as you would like (wait event, SQL monitor, Oracle Enterprise Manager, etc.). In the second part, we will share some indications on how to improve the performance (execution plan, table and index statistics, hinting, SQL baseline, etc.).
You will also learn the key points of how to address complex performance issues in a systematic way and to address performance issues in a quantitative way. A few examples and common pitfalls will be presented.

10:30 Oracle tools and Bindings with languages, Mariusz Piorkowski & Others
This tutorial provides an introduction to common Oracle database administrative tools: how they work, how to install and configure them, how efficiently we can use them. We’ll also provide some practice examples of usage. We will cover the following tools: PL/SQL Developer, rlwrap, Benthic Software – (Golden 6.0) and SQL Developer.
The second part of this presentation will address the topic of language bindings, including OCI, OCCI, JAVA, Perl and Python, for example.

For more information, please see the Indico page.

We are very pleased to announce the launch of the new IT website on 10 April 2012!

The aim is to replace many of the existing (and often out-dated) IT sites, and in particular the information content will be actively managed. Content editors have been identified, and have an active responsibility to maintain their pages.

It will take some time to move some of the asociated websites into the new structure, but we believe that deploying the new site now will already bring benefits.

Structure of the site

You will see that the site has been separated IT Staff content from User content. This is to ensure that the right information is clearly targeted to the appropriate audience.

This 'Noticeboard' page that you see directly under 'For IT Staff' will contain administrative and informative notices for staff (eg news relating to travel, meetings, department-wide socials etc).

The rest of the site should be fairly intuitive.

We hope this new site responds better to your needs and helps you find what you want, faster. Please do not hesitate to provide feedback - it will help us improve the site to help you. There is a Feedback link at the bottom of the page; alternatively e-mail it-webmaster@cern.ch and we will get back to you as soon as possible.

Bonne lecture...
