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

Federating / brokering clouds under control by SURF

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)

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?
