Background

Before the Poznan meeting...

Enric MitjanaScientific OfficerEuropean Commission DG INFSO/F3 - GEANT & e-Infrastructures

” I have consulted with several colleagues and none of us was aware of the existence of this task force. So, we thank you for letting us know about its activities. ”

Information request

› Beyond the information available at http://www.terena.org/activities/tf-storage/we would like to know:

› what were the current motivations for the participants in this TERENA TF and

› from which strategic perspective the TF looks at storage and clouds

› how it positions vis-à-vis the activities mentioned above and

› if it has plans to support these activities.

› TF-Storage found that it would be interesting to collect the NRENs’ strategic perspective on storage and cloud (if any)

Word Economic Forum

› Neelie KroesVice-President of the European Commissionresponsible for the Digital AgendaTowards a European Cloud Computing StrategyWorld Economic Forum Davos, 27 January 2011

› We see that many private, and increasingly also public, organisations are developing their own approaches to the use of cloud computing.

› But... there are a number of questions that need to be answered to make it happen in practice. These concern legal, technical and commercial issues.

› I have started work on an EU-wide cloud computing strategy. This goes beyond a policy framework. I want to make Europe not just "cloud-friendly" but "cloud-active”.

› We want to extend our research support and focus on critical issues such as security and availability of cloud services

› We will support pilot projects aiming at cloud deployment.› I want to have this in place no later than 2012.

Slide 4

Idea

› Collect the NRENs’ strategic view on storage and cloud (services) into a paper.

› Short document, 15-20 pages› Overview on the problem space, NRENs’ situation,

future perspectives, trends (if any)› References, use cases, examples...

› Not to define a common strategy of NRENs (not a primary goal) but try to be clear about the NRENs’ role in this arena.

› Benefits:1.TF-Storage participants (TERENA Community) can

have a more complete view on national activities.2.May help EC policy makers to take the right

assumptions.

Slide 5

TF-MSP and TF-Storage

› TF-MSP (NREN managers) looked at cloud and service outsourcing from a business/service perspective on 6-7 September 2010

› to explore Cloud Services, Commoditzation, New Business Models and Working Together

› TF-Storage participants (techie people) provided their view on storage and cloud

› SURFnet, CESNET, NIIF, PSNC

› (SWITCH), GRNET, HEAnet, UNINETT, JANET & RAL› Others may come...

White Paper

› I have started to compile a document including all the information available:

› Primary or production storage serves active applications and is accessed randomly.

› Secondary storage is used for data protection and is normally accessed sequentially

Cloud and P2P (networked) storage overview

Slide 12

› Cloud storage is basically a storage accessed over a network› Another networked storage technology (now more and more available)

relies on members of a group storing each other’s data. This technology is called peer-to-peer (P2P) storage.

TNC2010 outsourcing panel

› In case of universities and higher education institutes

› outsourcing of commodity application services (e.g., student e-mails, document sharing) to public clouds

› can be done with low risk (SaaS scenario).› However, joining forces at national level and let the NREN to

negotiate with the commercial cloud service providers on behalf of a group of universities can have significant cost benefits and can simplify the procurement process. NRENs can play the coordination role of national “buying syndicates” here.

› outsourcing of infrastructure related services (e.g., storage, computing) to public clouds

› has more risks for individual universities (IaaS scenario) concerning the service operation, data protection, authentication and access control issues.

› In case of these services the outsourcing to NRENs (where it is appropriate) has lower risk and universities can have natural trust in their NREN. NRENs can play the role of an infrastructure service provider or an infrastructure service proxy to public clouds here.

Slide 16

TNC2010 outsourcing panel

› In case of NRENs

› outsourcing of commodity application services (e.g., calendar system) to commercial clouds

› seems to be straight forward (SaaS scenario).› The NRENs should get rid of the commodity services and

concentrate on new service development and innovation for the benefit of their users.

› infrastructure-related services (e.g., network operation, videoconferencing, storage, computing)

› the mixing of NRENs own infrastructure service with public clouds seems to be a value-added IaaS scenario.

› NRENs can hide the non-attractive features of public clouds and provide commodity cloud service to universities with tailor-made features (including federated access, data protection assurance, etc.) exploiting public cloud back-ends.

Slide 20

Strategy in national data storage

› Storage resources (e.g., direct block-level access) vs. Storage services

› Traditional primary storage vs. Networked secondary storage (e.g., backup/archive)

› Storage service at institutional/national vs. European level

› Serve institutions vs. individuals

› Attaching cloud storage vs. Becoming a cloud storage provider

Slide 21

NRENs’ strategy in e-Infrastructure services

› Focus on (cloud) storage services1. Virtualisation (resources): IaaS, architecture2. Federation (access): AAI, SSO3. Integration (services): combine services, peering

with commercials, commoditisation

› Trends in:› Technologies...› Capacities: 0.5 PB – 15 PB› Services: iSCSI, WebDAV – content management,

metadata, digital media - Cloud
