Cloud deployment models

Community Cloud:

external part (optimal, made available) for specific usergroup

6

Community cloud drivers

- Demand for IaaS services- Service improvement

- Ease of use- Federated authentication- No vendor lock-in

- Cost reductionefficiency, procurement

- Legal aspects- Integration with network- SLA- Emphasis on Green computing

- For full or hybrid use, disaster recovery, …- Customize to our community

SURFnet institutions and continuity

- This scared many in 2002:

- It’s still a “hot topic”(But how do we ensure continuity best?)7

IaaS pilots

- Little commitment to use existing overcapacity (and legally complicated?)

- Pilot with institutions:- in the Netherlands:

- VMware vCloud director- Use platform from GreenQloud

- Commercial cloud outside Netherlands (GreenQloud)- Different characteristics / use-cases- Focus on Green,

energy, cooling, equipment- Network aspects (inter domain, latency)

GreenQloud, friendly portal

13

Network integration- Networking to commercial IaaS cloud

- Via Netherlight, NORDUnet, …- Use NREN-network capabilities (lightpaths)

- Start machines behind own firewall?- Use NREN IP-space?

- Reduce networking cost- Investigate latency impact

Influence on applications

- Applications run outside network,different firewall or behind own firewall

- Latency

Important for Dutch privacy law!

so… what about

US suppliers…

Iceland = OK

16

Green IT (1)- Efficiency of cloud services (containers, pay-per-use stimulus)- Power source / mix is important, not only about PUE

17

Green IT (2)- GreenQloud’s focus on Green (not just energy source)- Use other countries strengths

Cost of storage- Decide what storage you pick for what application

- Expensive hardware, software, or “COTS” and open (source)?SURFnet research 2010:http://tinyurl.com/open-storage-scouting-v1-0-pdf

Storage virtualization and scalability

22

Storage

- (Not all) storage needs to be expensive- High available SAN

NetApp metrocluster, open-e, DRBD & iSCSI, …- Distributed filesystems / Scale-out (performance)

IBM GPFS, Equallogic, F5, NetApp GX, GlusterFS, …

- Migration of a VM over WAN- VMware support LAN, works (limited) over WAN- Storagevendors limit distance synchronous replication

- SURFnet research on VM migration with DRBDhttp://www.surfnet.nl/Documents/drbd-vmigrate-v1.1.pdf

We need you!

- You as a community determine if we go ahead with this (and this is a good time to provide feedback)…

- What features or conditions are most important?

- What does it take to persuade you to use the Community Cloud, if it were build?

- What do you see as potential obstacles in the adaptation of a Community Cloud?

- Are you interested in participating in the pilot?
