9th TF‐Storage Meeting in Athens

Open discussion on IaaS and clouds

9th TF‐Storage (& cloud) Meeting in Athens

• „TF‐Storage goes to clouds”:

TF‐Storage meeting @TNC conclusions:

P ti i t d th d f NREN t thi k i l b t – „Participants expressed the need for NRENs to think seriously about cloud infrastructure and services.” – „Only a large‐scale, pan‐European Cloud initiative can provide the economic benefits and technical advantages demanded by the economic benefits and technical advantages demanded by the global research and education user community”

9th TF‐Storage (& cloud) Meeting in Athens

• „TF‐Storage goes to clouds”

items to discuss:

– Is the European‐level inititative for establishing the cloud services necessary in your opinion? – Peter’s questions from the green paper: (NRENs’ Strategic Perspective on Storage and Cloud: Build or buy)

http://www.terena.org/activities/tf‐storage/Storage‐and‐cloud‐v5.pdf

– „Is there any chance to build a large scale cloud infrastructure jointly by NRENs for the benefit of the European R&E community?” – „Is there any chance to establish a demand aggregation function towards commercial cloud infrastructure providers jointly by NRENs for the benefit of the European R&E it ?” community?” – What can we (TF‐Storage) do at the moment?

Why on European level?

• „TF‐Storage goes to clouds”:

Why on European‐level?

• Scale large enough
• Elasticity
• Flexibility
• Redundancy
• Resilliency
• Resilliency
• Optimisation
• Sustainability

9th TF‐Storage (& cloud) Meeting in Athens

• „TF‐Storage goes to clouds”:
• Why to make it on a European level?

– A lot of service providers and cloud nodes are needed:

• High redundancy and physical distribution of elements and data:

– Resilliency – see massive disasters Resilliency see massive disasters – Data safety – replication – Elasticity: » Ability to accomodate huge peak loads » No need for overprovisioning of the resources locally (on the national level) » No need for overprovisioning of the resources locally (on the national level)

• Multiple countries involved

– The whole ‘business’ resistant to local political/economical issues

– Data distribution/storage and access optimisation possible:

• E.g. data (centers) located depending
• n personnel vs energy costs comparison
• Data access effective due to

existence of multiple copies (mirrors) of the data objects; caching possible

• „TF‐Storage goes to clouds”: Why ‘involve’ NRENs?

– NRENs=Network:

• Performance

Performance

• Easy access

– NRENs – trusted:

• Users trust NRENs! Why should’nt they store data in NRENs clouds?

NREN i i b ildi i – NRENs experience in building services

• see e.g. Eduroam
• ... and tailoring them to client needs

– ‘Elasticity’ in terms of:

• Openess to implement the requested features
• Some means of pressure in hands of users
• Elasticity cost model we can implement

(pay as you go approaches not suitable) p y y g pp

– Costs:

• We can be cheaper... (BTW have we to be?)

– ‘economy of scale’ – we’re non‐profit p – other factors – examples later on

– Sustanaibility, no surprises

• „TF‐Storage goes to clouds”: Why ‘involve’ NRENs?

NRENs benefits and possible roles: NRENs benefits and possible roles:

• Truisms:

Users stay with NRENs > don’t go somewhere else – Users stay with NRENs ‐> don t go somewhere else – Network gets used ;)

• Further truisms:

Further truisms:

– NRENs can be both providers and users of Clouds:

• Private clouds as the NRENs service’s backends:

E g Filesender Video stream archival/storage/serving – E.g. Filesender, Video‐stream archival/storage/serving – NRENs can better manage the resources thanks to Clouds

• NRENs cloud services for the others:

– Providing public or private clouds for the users – Brokering the own and 3‐rd party clouds services

• „TF‐Storage goes to clouds”:
• How to make the European (or even national) cloud the reality:

p y

– Let’s go on (on the technical level):

• Explore Cloud technology on the paper and in practice:

– Paper work within TF‐Storage? » volunteers to contribute to the cloud technology compendium? – Piloting the technologies within TF‐Storage? » Anyone interested? » Anyone interested?

• Develop the new technology if we find this needed...

– Possibly apply for R&D projects to EU...

– Let’s also act on the higher level:

• Work on high level architectural design issues:
• utsourcing of services in general

– outsourcing of services in general, – security and privacy issues, – maybe standardisation / best practices, etc.

• TF Storage goes to clouds”: what can we do now?

9th TF‐Storage (& cloud) Meeting in Athens

• „TF‐Storage goes to clouds : what can we do now?

– Some practical things to do (1): – Some practical things to do (1):

– 1st step: Collect our knowledge on cloud (storage) solutions: – E.g. do a comparison of what we have in NRENs: – Agree on the set of the attributes of the national deployments of cloud storage systems, such as: p y g y

– Total capacity, – Replication, encryption etc. – Client Data access model and interface / APIs: Client Data access model and interface / APIs: e.g. Block‐ vs file‐ vs object‐level – Storage backend: DAS, NAS, CAS, Storage Cloud: IaaS? SaaS?

– Put the table into the TF‐storage wiki Put the table into the TF storage wiki – Then try to fill in this table – all interested NRENs – Any volunteers to coordinate this (or at least participate)

– Some practical things to do (2): Some practical things to do (2):

– 2nd step: do some piloting / test deployment of cloud storage middleware/solutions together middleware/solutions together – e.g. some NRENS to replicate national solutions and build an international cloud storage pilot – Implementation: – What middleware looks most promising? – What applications seem to be most interesting for piloting? What applications seem to be most interesting for piloting? – Are there any volunteers to do pilot together?

High level things todo: – High‐level things todo:

– Work on high level architectural design issues: –

• utsourcing of services in general,

– security and privacy issues, maybe standardisation / best practices etc – maybe standardisation / best practices, etc. – Act on the political level – Do lobbying of the idea high enought and as broadly as possible Do lobbying of the idea high enought and as broadly as possible

– Gather a critical mass of service providers (NRENs, commercials) – Assure the support at the EC level – Assure the support at the EC level (and funding needed for R&D and or piloting if needed)
