4. Key Issues
1. How has Web computing evolved and how will it impact
future application strategies?
2. How will cloud computing evolve to become a key
sourcing strategy for the enterprise?
3. How will the combination of Web and cloud computing
become the primary IT strategy for many enterprises?

5. The Web Is Still Not Dead
The
Web is
dead.

6. While the Internet Is Middle-Aged, the
Web Is Still a Young Pup
• 2009 saw two special birthdays: Internet, 40 years old, Web, 20
years old
• The Internet — network of networks providing ubiquitous two-way
communication with billions of users around the globe
• The Web — UI that makes the Internet usable by the majority
• The Web as architecture - WOA
• Enterprise Web
- The Web is the primary UI for enterprise apps and content
- Customer-centric Web strategies retain and grow customers
- Portals increase user satisfaction via personalization
- Web AD tools are pervasive
- Majority of new apps are being built with Web front ends
- Cloud computing is a natural outgrowth
• Consumer Web — just look at the impact on travel, media,
retail, libraries, …

7. Web 1.0 Web 2.0 What’s Next?
Original Web 1.0 Web 2.0 Modern Web
• HTTP, HTML, • Web 1.0 + XML, • Web 2.0 + HTML5
URI Ajax, … • Mobile, cloud, real
• Consumed only • Consumed by time, …
by humans humans &
• Many readers, machines, Many
few authors readers, many
authors
• Communicative,
collaborative,
community-
friendly

8. The Future Web
• Is Contextual • Runs in Parallel with
• Is Mobile Native Apps
• Relies on HTML5 • See the Return of Browser
Wars
• Runs on the UXP
• Is Consumer-Drive
• Is Social
• Is Rife with Commerce
• Runs in the Cloud
• Is in the Middle of the Net
• Is Real-time Neutrality Controversy
• Is an Architecture
Mobile The Internet
of Things
Programmable The Cloud
Global and Geo-
The Social Web located

9. The Future Web is Contextual
Context-enriched services will use information about the end user
to anticipate an end user's immediate needs and proactively offer
more-sophisticated, situation-aware and usable functions.
Enterprises can better target consumers and deliver on the promise of
increased customer intimacy
Compound context-enriched services will emerge between 2010 and 2015

10. The Future Web Is Mobile & Ubiquitous
•~5 Billion Mobile Phone Subscriptions
• Penetration > 100% in Some Markets
• SMS – 6.3 Billion Messages/Day 6.7 billion connections,
• Mobile Data Traffic Rising 2015
(140,000Tb/month > total voice traffic)
>$1 trillion direct voice +
• 10% of Google Searches data service revenue per
• 150 Million Facebook Mobile Users 2014 annum, multiple $ billions
in indirect revenue, e.g.,
The service advertising
and social era 2013
Data revenue exceeds
2012 voice revenue in
advanced markets
2011
The
application 2010 5.1 billion connections
era
.....
The device era

14. The Future Web Will Be About Browsers
and Operating Systems
• An example of a “Web OS”
• Chrome browser +
• Platform or OS?
• Compare it to?
- Windows No: MacOS, No
- Network Computer? Yes
• Why two Linux desktop Oses from Google?
- One is a platform (Android), One is not
(ChromeOS)
- Native Apps matter more and for longer in
Mobile space
• “Netbook Computing” .

15. The Future Web is Social
• Ham Sandwich:
Tells you what someone
you barely know had for lunch
(on Twitter)
• Leadership of the Free
World: Helped determine
the last U.S. presidential
election
• Open Channels for the Whole
World: U.S. State Dept. asked
Twitter to delay upgrade to allow
"tweets" about Iran election to flow

16. The Future Web is Real-Time
twitter gets there first

17. The Future Web is an Architecture
• "Web as platform" is really Web as The Key to a
architecture (WOA) Successful Spanning Layer:
- Coupling is exposed as changeable The Hourglass Model
uniform data (IFaPs), not hidden as
fixed custom code Users
• IFaPs are the narrow waist Generic
- Identifiers aka Addresses, Foreign
Extensible
Keys Complementors
- Formats aka Schemas, Envelopes,
Containers Simple IFaPs
- Protocols aka Processes, Message
Enablers
Exchange Patterns
• Examples Federated
- Web: URL, HTML, HTTP
Providers
- Global Containerized Shipping: Bar
Codes, TEU Steel Box, Container Port
Operations

18. The Future Web is Consumer-Driven
Search engines
External Web-e-mail
Aggregators (news…other content)
Shopping and entertainment sites
Wikis (as reader)
Social network sites
Forums… Net news groups
Google applications
Personal Web desktops
Blogs (as a reader of external blogs)
Blogs and Wikis (contribute)
External IM tools
Web storage
Web prod. suites (not Google Apps)
Social tagging sites User Reports

From the Web From the Enterprise
Definition: cloud computing is "a style of computing where scalable and elastic IT-
enabled capabilities are provided 'as a service' using Internet Technologies."

20. Gartner's Definition of Cloud Computing and
the Critical Attributes of Cloud Services
Gartner defines cloud computing as "a style of computing where scalable and
elastic IT-related capabilities are provided 'as a serviceusing Internet
technologies."
5 Attributes That Support Outcomes
Consumer concerns are abstracted from
1 Service Based
provider concerns through service interfaces.
Services scale on demand to add or remove
2 Scalable and Elastic
resources as needed.
Services share a pool of resources to build
3 Shared
economies of scale.
Services are tracked with usage metrics to
4 Metered by Use
enable multiple payment models.
Services are delivered through use of
5 Internet Technologies
Internet identifiers, formats and protocols.

23. Slicing the Cloud: The Public to Private Cloud
Services Spectrum
Private Public
Hybrid
Company/Entity No owned Assets
Owned Assets and Distinctions are made at the extremes but and Scope is open to
Scope is Bounded by many examples exist somewhere between. anyone who can pay
Exclusive for service as
Membership defined delivered by provider
by company/Entity
The real issue is: How to deliver cloud services in my
private scope to gain as many cloud computing benefits as I
can while maintaining a degree of control, not whether or not
I have a private cloud.

24. What are the Benefits and Challenges of
Public Cloud Computing?
Significant Potential Benefit But Tough Problems Remain
• Speed, Flexibility, Agility • Data/Process Location & Isolation
- User self service - Security, privacy & ownership
- Rapid deployment & change • Regulatory, Compliance & Policies
- Address highly and/or - Limits, e-discovery, investigations
unpredictable resource demands
• Portability between Providers
• Financial Benefits
- Lack of standards, vendor lock-in
- Cost savings (perceived & real)
- Move from capital to operating • Provider Trust Management
expense - Transparency to provider operations
- Pay for use & "free" software - Immature vendors and certifications
• Simplicity and Convenience • Uncertain Failure Remediation
- Procurement (transaction, - SLA guarantees, redundancy
contract, service levels)
• Integration and Process Integrity
- Encourages use of standardized across the cloud
resources/applications
- Technical & Support issues
- Access (browser, menus, simple
APIs) and global reach • Bandwidth & Latency
• Capabilities - Accessing or integrating "clouds"
- New solutions not feasible before • Licensing Issues
- Superior security and reliability for • Uncertain Financial Models

29. Recommendations
The Web changes everything, again. Cloud computing amplifies existing
change and introduces new disruptive changes. Denial is pointless.
WOA should be adopted by enterprises when appropriate. Simple interfaces
and REST/POX approaches should be used when possible.
Leverage mashup-style composite applications developed by traditional
developers and end users.
Determine when you will be a consumer and when you will be a provider of
cloud services.
To optimize for cloud computing, design for stateless linear scalability,
parallel processing and distributed data
The consumer-centric public Web leads this shift. Encourage consumer
technology experimentation in your enterprise.
The social component is large, and management should lead cultural change
by example.
