2. Cloud Computing?
• Cloud computing is a model for enabling
ubiquitous, convenient, on-demand network
access to a shared pool of configurable
computing resources (e.g., networks, servers,
storage, applications, and services) that can
be rapidly provisioned and released with
minimal management e ort or
service provider interaction*
• Cloud Computing ≠ Web 2.0

4. Motive
• Cloud cloud cloud — data explosion
• Mobile mobile mobile — device explosion
• Go go go — study + work + play +

11. Basis of IaaS is Virtualization
• Increases e ciency (cost, consolidation,
abstraction, administration)
• Despite the shared hardware / point of
failure

12. Availability
• (near) Real-time transfer at failure of
physical hardware, or when planned,
migration without downtime of running
virtual machine and its storage

13. Business Continuity
• Disaster at University of Twente in 2002
increased focus for on-site redundancy
• However for continuity and disaster recovery
virtualization is a better solution

14. Cost of Storage

15. Drivers Cont’d
• Cost reduction
- Budget cuts
- Rising power costs
• Service improvement
- Better service provisioning
- Best-of-breed services
- Increased agility in software deployment
• ‘Green Computing’ trend
- Reduce energy consumption
- Data centers can use >10% of power for an entire
campus
- IT produces 2% of global carbon dioxide emissions

16. Cloud Models
Community

17. IaaS Cloud Models (2)
• Private cloud
- enterprise owned or leased
• Public cloud
- sold to the public, mega-scale infrastructure
• Hybrid cloud
- composition of two or more clouds models
• Community cloud
- shared infrastructure for specific community
Community Clouds - Cloud Seminar - 16 June 2011,- Utrecht 17
Thursday, June 16, 11

18. Level of Adaptation
• Very gradual migration towards public cloud
- First start with a private cloud
• Hybrid operation for years to come (5-10
years)
• Local data center is becoming a private
cloud, driven by widespread usage of
virtualization
• More and more resources in own data center
ready for migration to the cloud
• Migration at di erent levels: currently mostly
at IaaS, moving to PaaS and SaaS later on
mostly for generic services (e.g. email, etc.)

19. Community Cloud
• Functional features mostly in line with public
cloud
- Virtualization / image & instance management
- Storage / object & block level
- Self-service through management console
• Added value of community dimension
- Control — Legal and Innovation
- Saves money
- Su cient flexibility to meet the community’s needs
- Standardization to prevent lock-in
- Network integration
Community Clouds - Cloud Seminar - 16 June 2011,- Utrecht 19

20. Full Control
• Full control over data location
• Mechanisms to enforce storage within a
single legal jurisdiction
- Only a single (Dutch) legislation is applicable
- Reduces the complexity and costs of compliance to
a very significant degree
- EU Data Protection Directive specifies that national
laws will generally apply when personal data
processing is carried out
• Community controls at which points to
innovate
- Stronger negotiation position
- Easier to swap suppliers

21. Network integration
• Close integration with SURFnet backbone
• Close integration with own network
• Dedicated lightpaths possible
• Low latency
• No costs for data communication (depends
on billing model)

22. Saves money
• Combined network and Community Cloud
subscription o ers benefits (e.g. reduced
costs for bandwidth)
• Central support for operation and
maintenance
• Shared purchasing of IaaS
• Reduced power consumption
(at least locally)

24. Federated model
• Sharing of over capacity
• Not supported by current products
• Di cult to tackle liability issues
- What is the legal impact of a service outage?
• Billing
- Who pays for support/maintenance and operational
costs?
=

25. Brokered model
• Takes care of trust establishment and
contract settlement
- just one party to trust and one contract to sign
• Broker can handle disputes in the cloud
• More transparent in terms of
- Operation and Accountability
- Awareness raising
- Guidance on expectations regarding the use of the
Community Cloud
- Levels of security
- Meeting legal obligations (compliance)
• No need to tender
Community Clouds - Cloud Seminar - 16 June 2011,- Utrecht 25

26. Brokered model (2)
• Continuity
- Commercial providers may go out of business
• Institutions do not need to test themselves
whether a cloud provider is e ectively
mitigating risks
- Broker can do that for the community
• Broker can provide value-adding services
- Federated identity management, lightpaths,
resource federation
• Supported by various vendors and products

27. Self Service is Essential
• Virtualized environment, component
“shopping”
• Self-service! Public: pay-as-you-go
• Support for Private, Hybrid, Public
Hardware vendors
• Quickly up and running:
- Website down? Data available? Recipe!
- Extra load (e.g. spam filtering)?
- Datacenter loss?
- Elasticity also in a private cloud.
• Optional security: VPC, VPN, VLANs

28. Demo Self Service

29. Done deal?
• Licensing?
• Security and privacy?
• Standardization?
- Data and customer application portability
- Common interfaces, semantics, programming
models
- Federated security services
- Provisioning
• Accounting & billing: pay for what you use
• Overall SLA of a multi-cloud environment
o ering may be hard to predict
• Migration not straight forward

30. Current Activities SURFnet
• SURFnet is using external private cloud
(SURFcloud) to run their services, but on
self-owned hardware
- Load balancing experiments with Amazon EC2
• Experimental setup of community cloud
- For the moment in-house at SURFnet
• Expected participants
- University of Groningen
- To make website redundant
- Open University
- For their OTAP environment

31. 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?
