tasks• Planning activities for tasks 1 and 2• Definition of:– Schedule– F2F meetings and WebEx conferences

• Administrative aspects (Richard McLennan)

Friday 18 January 2013 Fisrt EGI CTA Virtual Team meeting 2

Virtual Teams in EGI• Goal– A flexible and dynamic means to rapidly bring together

community members– They have a well-defined series of tasks to meet a specific

goal to be achieved in a relatively short period of time• Focus– Increase the number of EGI users

• Activity domains– Marketing & Communication– Strategic Planning and Policy Support– Community outreach and events for new users– Technical outreach and support to new communities


Why a VT for CTA in EGI• EGI is interested to collaborate with one of the

biggest astronomical ESFRI projects– An important Astronomical Community hooked

through CTA• CTA can leverage on the EGI ecosystem to

find a solution to its challenges• Some of the CTA challenges– Procurement of computing resources– Procurement of data storage resources – Easy user-friendly ways to get access and use them


Possible solutions• Procurement of computing resources and data storage

resources– Distributed computing resources based on different

technologies (HPC, HTC, Clouds) could represent a possible solution

– This is matter of the CTA computational model under preparation

• Easy user-friendly ways to get access and use such resources– A SSO authentication and authorization system– Science Gateways

• The CTA community is wide and trans-national and this implies non trivial issues to solve for the SSO system


Status of the CTA VT• VT submitted for approval at the end of November

2012• Approved by EGI in early December 2012• Call for interest (for NGIs) closed at the end of

December• Start on January 7th 2013• End on July 7th 2013• CTA VT mailing list:– [email protected]

• Wiki page:– https://wiki.egi.eu/wiki/VT_Technology_study_for_CTA


VT startup phase• Preliminary restricted teleconference held on Jan 10th (Nadine,

Gergely, Richard, Claudio)• Topics raised from the discussion

– The creation of an identity federation is part of the VT activities (task 1)• Precondition requested by the SSO authentication system• This activity will leverage on the support from NGIs

– During the first three months tasks 1 and 2 will run in parallel– Task 1 will span over the whole VT lifetime

• Essential to involve all potential CTA end users– The users requirements gathering process will start from already

existing user requirements documents…• …then, missing requirements related to SGs and SSO have to be

identified through interactions with the CTA end users community– All people interested to join the VT are requested to register their

name on the VT wiki page


Goals of the Virtual Team

N Topic Task1 Establish a social network between CTA and EGI through the support

teams of the National Grid Infrastructures;Creation of an Identity Federation for the CTA collaboration.

Task 1

2 Use the social network to gather CTA user requirements concerning:a) Web based scientific gateways operated for the CTA community, making DCI resources and services from the NGIs accessible for CTA members;b) A Single Sign On (SSO) authentication, internationally federated, mechanism that would make web-based scientific gateways accessible for the CTA community.

Task 2

3 Mapping the identified CTA requirements to solutions that exist within the EGI community and within its partners, such as the NRENs.

Task 3

4 Document the findings and define a roadmap for implementing, deploying and operating an SSO solution and one or more scientific gateways for the CTA community.

Task 4
