4. So, What is Cloud Computing?
The 451 Group: “The cloud is IT as a Service, delivered by IT resources that are
independent of location”
Gartner: “Cloud computing is a style of computing where massively scalable IT-
related capabilities are provided „as a service‟ across the Internet to multiple
external customers”
Forrester: “A pool of abstracted, highly scalable, and managed infrastructure
capable of hosting end-customer applications and billed by consumption”
Wikipedia: “A style of computing in which dynamically scalable and often
virtualized resources are provided as a service over the Internet. Users need
not have knowledge of, expertise in, or control over the technology
infrastructure "in the cloud" that supports them.”
“A large pool of easily usable and accessible virtualized resources (such as
hardware, development platforms and/or services). These resources can be
dynamically reconfigured to adjust to a variable load (scale), allowing also for an
optimum resource utilization. This pool of re-sources is typically exploited by a pay-
per-use model in which guarantees are offered by the Infrastructure Provider by
means of customized SLAs.”
Vaquero, Rodero-Merino, Caceres, Lindner

10. Why Cloud Computing?
• Cost reduction
− Benefit from economies of scale and experience curve
− Predictability of spend
− Avoids cost of over-provisioning
− Reduction in up-front investment
• Risk reduction
− Offload risk or running the data-centre, data protection, and disaster recovery
− Reduces risk of under-provisioning
• Focus on core competency
− Reduce effort and administration related to IT
− Automatic service evolution
• Flexibility
− Roll-out new services, retire old
− Scale up and down as needed; quickly
− Faster time to market: Lower barriers to innovation
− Access from any place, any device, any time

11. Agenda

12. Mysteries, Myths and Misconceptions
• What is IPv6?
• Great solution! What‟s the problem?
• Why not just NAT?
• 中国, 日本, 대한민국, 臺灣, 新加坡, ,
• ETA 2020
• What‟s the business case?
• No worries – it will just happen automatically
12 18 June 2009

13. What is IPv6?
• Internet Protocol (IP) is the network protocol that
underpins the Internet
• IPv6 is version 6 of the Internet Protocol (IP)
• The current version (IPv4) was designed in the
1970s and standardized in 1981.
• IPv4 address space will eventually "runs out“.
This will occur at a global level...
• IPv6 also solves many problems IPv4 such as
security, auto-configuration, and extensibility.
13 June 2008

14. Need for IP address space
Aren‟t 4‟294‟967‟296 addresses enough?
• Uneven and inefficient
distribution!! Class IP Address Pool
• US-Centric
A 224~16‟777‟216
− India has 3 Class B
− HP has 2 Class A B 216~65‟536
• Emerging Service Providers C 28~256
− China Mobile has over 415
million subscribers
• Subscriber growth:
2 million/month ARIN advised IPv6 migration
− Several operators have over 16 – May 2007
million
− How can they all be
simultaneously data-enabled?

15. NAT Problems
• Overhead of unnecessary translation
• Protocol incompatibilities
− E.g. IPsec
• Breaks peer-to-peer applications
− Instant messaging
− Interactive games
− VoIP
− Real-time collaboration
and sharing
• Netmeeting, BitTorrent, Groove
• Limits implementation of application servers
− How far can you distribute your web-services?
− Grid computing
Building work-arounds for everything NAT breaks is an unnecessary
and inefficient effort!

17. Additional Benefits
• Availability
− Anycast reduces single-point-of-failures
− Removal of NAT
− Authenticated access inhibits Denial of Service attacks
• Agility
− Improved Host and Router Discovery
− Flexible Renumbering and Autoconfiguration
• Better Traffic Flow
− Efficient and Extensible IP datagram
− Efficient Route Computation and Aggregation
− Efficient IPv6 Header Compression
− IP Header Flow Label to support quality of service
• Even when all data is encrypted

19. Synergies between IPv6 and Cloud
• Massive scalability
− Hierarchical internal address space of provider
− Avoid connection brokers (ALG/NAT)
• No “need” for NAT
• Always connected user experience Mobile IPv6
• Customer connectivity
• “Easier” implementation
• Unified Communications
19 18 June 2009

20. Scalability
• Large number of virtual interfaces
• Beyond capacity of CGN
• Direct connectivity required
− Impossible to distinguish between internal and external
systems
• Intra-cloud
• Inter-cloud
• User-access
• P2P potential
20 18 June 2009

21. Mobility
• Seamless user experience
• Always Connected users
− Move from one access network to another
• Cloud Abstraction
• Workload rebalancing
− Virtual Machine relocation
21 18 June 2009

22. Automatic deployment
• Ease of provisioning
− Stateless autoconfiguration
− Dynamic renumbering
• Dynamic allocation of capacity
− Autoconfiguring virtual machines based on demand
fluctuation

28. HP IPv6 support
• HP is implementing IPv6 support in stages with the goal of ensuring a
smooth transition and deployment where IPv6-updated products can
take advantage of IPv6, without impacting existing functionality.
• HP supports IPv6 across many of its product lines today.
• HP platforms support transition mechanisms and gateways to
interoperate with IPv4.
• HP has already delivered IPv6 products across:
− HP Business Critical Server and ProLiant platforms (HP-UX, Tru64
UNIX®, OpenVMS, NonStop Server, Linux, and Microsoft® Windows)
− ProCurve high-end switches through its ProVision ASIC offers full support
for IPv6 in hardware; ProCurve Switch series 8200, 6200, 5400 and 3500
− HP Enterprise JetDirect and LaserJet printers;
− HP Business Technology Optimization Network Management Center
platform and Opsware Network Automation System software, now called
HP Network Automation (HPNA)
