Technical Dimension

WEB WEB 2.02.0Net Infrastructure:

Huge improvements in speed, bandwidth, availability, and reliability over the past 10 yearsBroadband networks worldwide, “flattening” of the worldThe large computing center is back (but we don’t know its location anymore)Computing is on its way into the cloud Nick Carr: The Big Switch

Functional Dimension

WEB WEB 2.02.0

•Rich Internet Applications (RIAs) based on technologies such as Ajax, REST, Flex, AIR, Silverlight, JavaFX, several others

•Applications move from the desktop to the Web, into the cloud

•Software as a Service (SaaS) as the new ASP (application service provisioning) model

RIA Example: Gliffy

Online Diagram Software - Gliffy

Online diagram software. Create and share flowcharts, network diagrams, floorplans, user interface designs and other drawings online with the Gliffy diagram ...www.gliffy.com/

RIA Example: ThinkFree MyOffice

Java-based word processor, spreadsheet, presentation package that offers MOffice compatibility.www.thinkfree.com/

RIA Example Shutterb.org

Shutterborg is a free online word processor / document editing system. Edit HTML web pages, MS Word docs and PDF documents.shutterb.org/

RIA Example Personalization: My iGoogle Page

also: Pageflakes, eskobo, Netvibes, Protopage, Microsoft, Yahoo!, Cleverset etc.

Cloud Computing

Applications: Desktop Web Cloud

SaaS – Software as a Service PaaS – Platform as a Service IaaS – Infrastructure as a Service

Cloud Computing Architecture

SaaS Example: AWSAmazon Mechanical Turk Mechanical Turk offers access to a virtual

community of workers that are available to help you accomplish your business goals. A robust set of APIs and command line tools enable you to programmatically distribute tasks that require human intelligence to a widely distributed, on-demand workforce.

aws.amazon.com/mturk/

Amazon EC2

Applications, storage space, servers, computing power, all in the cloud IaaS

(More) SaaS Examples

Zoho offers a suite of online web applications geared towards increasing your productivity and offering easy collaboration. Zoho's online office tools ...www.zoho.com/

organizer, calendar, planning, conferencing, db apps, collaboration, time tracking, accounting, payroll, project mgnt

Syncplicity The only automated sync, back-up,

collaboration and file management service powerful enough for a business user and easy enough for a novice. Secure, anywhere access to your files.

similar: Wuala, SugarSync, Mozy, Box.net, Dropbox

Next Step: (Sales) Force

Up to now: on-demand customer relationship management (CRM), marketing, Web analytics as hosted service

Now: platform to enable developers to create and provide arbitrary business applications on-demand

Why This Is Attractive

No software installation on private PC, no upgrades, no patches, no service packs, no maintenance

No license renewal when computer is exchanged

All data resides on the Web

“Pay-as-you-go” business model, i.e., payment based on usage

Implication: Low Startup Costs

the long tail

Result: “Long Tail” Effects

• Startup companies need small initial investments only in order to run their business on a world-wide scale

• 60+ generation enters the Web

Data Dimension

WEB WEB 2.02.0

Creation of data collections by computers as well as by humans:

•Tags, registrations, evaluations, comments, online diaries / blogs, emails, bookmarks, CVs

•Click paths, storage of tracking data, search engine indexes

Usage of these collections:

•Recommendations, creation of profiles, online communities, personalization

•Context-dependent advertising

•Mash-ups combining data from multiple sources
