Agenda

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.”

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

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 , भा�रत,รราชอาณาจั�กรไทย

• ETA 2020• What’s the business case?• No worries – it will just happen automatically

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.

Need for IP address spaceAren’t 4’294’967’296 addresses enough?

• Uneven and inefficient distribution!!

• US-Centric− India has 3 Class B− HP has 2 Class A

• Emerging Service Providers− China Mobile has over 415

million subscribers• Subscriber growth:

2 million/month

− Several operators have over 16 million

− How can they all be simultaneously data-enabled?

Class IP Address Pool

A 224~16’777’216

B 216~65’536

C 28~256

ARIN advised IPv6 migration – May 2007

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!

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

Agenda

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 April 8, 2023

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 April 8, 2023

Mobility• Seamless user experience• Always Connected users

−Move from one access network to another• Cloud Abstraction• Workload rebalancing

−Virtual Machine relocation

21 April 8, 2023

Automatic deployment• Ease of provisioning

−Stateless autoconfiguration−Dynamic renumbering

• Dynamic allocation of capacity−Autoconfiguring virtual machines based on

demand fluctuation

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)

Summary• „Cloud Computing“ means different things to

different people− That doesn‘t stop us from implementing it

• Cloud Computing has many benefits− Some Enterprise advantages can also be covered through

Private Clouds• IPv6 adoption is beginning now

− HP is a leader in IPv6• The market must begin to plan for IPv6 now

− It is easy to enable IPv6 in a simple environment• You can ignore IPv6 but that won’t stop it!
