Personalidade de 2006 VOCÊ!
In 2006, the World Wide Web became a tool for
bringing together the small contributions of
millions of people and making them matter
Time, December 25, 2006

• A Web 2.0 está criando novas fronteiras para a
  colaboração e a inteligência coletiva.

O que é a Web 2.0?
Web 2.0 is a set of economic, social, and
technology trends that collectively form the
basis for the next generation of the Internet - a
more mature, distinctive medium characterized by
user participation, openness, and network
effects. Source Web 2.0 Best Practices and
Principles, OReilly Radar
9
O que é a Web 2.0?
Web 1.0 was about connecting computers and making
technology more efficient for computers.
Web 2.0 is about connecting people, and making
technology efficient for people.
Web 2.0 changes the way businesses interact with
customers
Expanding from dozens of markets with millions of
people to millions of markets of dozens of people

O conceito da Cauda Longa...

• The Long Tail
• Targeting niche markets - expanding from dozens
  of markets of millions of people to millions of
  markets of dozens of people
• Examples Google, Netflix, Amazon
• Network Effects
• Product or service is more valuable the more
  people that use it (e.g telephone, email, instant
  messaging)
• Examples eBay, MySpace, Craigslist

14
Long-tail Software Situational Applications
15
Definition Situational Applications

• Situational application development involves
  aggregating, customizing, or extending an
  existing collection of simple web services
• Built to solve an immediate, specific business
  problem
• Typically performed by non-traditional
  programmers (e.g., business professionals,
  analysts, other IT staff, etc.)
• Makes use of pre-existing software components or
  services such as spreadsheets, report generators
  or vertical business applications already in use
• Manipulates static and increasingly dynamic
  content information-centric
• Accelerated by a community-based development
  approach

Integration is pushed to the edges and on a
global scale
16
The Accelerating Evolution of Software
Situational application development paradigms are
emerging which will challenge traditional IT
development

• New tools and approaches to develop situational
  applications applications built with
  simplicity, efficiency, and just enough function
  to solve the business problem at hand are
  emerging
• Proliferation of easy-to-use software, tools and
  techniques (e.g., Web 2.0, LAMP, PHP)
• Wide availability of domain-specific web services
  (e.g., Google maps, UPS, NoAA)
• Simple application paradigms to manipulate,
  integrate, and publish dynamic content (e.g.,
  QEDWiki)
• The rapid growth in computer literacy and
  non-traditional programmers
• These trends will result in significant
  challenges for enterprise IT environments
• Supporting and enabling community-based
  development within the enterprise
• Refactoring interfaces to enterprise applications
  as consumable web services
• Dealing with the growing heterogeneity in the IT
  environment
• Facilitating the development, deployment, and
  management of situational applications
• Situational application development approaches
  will fundamentally change the way applications
  are developed and deployed, accelerating the
  proliferation of consumable web services

Applications built by LOBs and end-users,
customizing and aggregating services as needed

• Application built by one person in one day,

19
Situational Applications The primordial mashup
20
Mashups Script, scrape, shred, snip, mash,
map. That is the new programming fashion. .

• Mashups like Coffee integrate disparate data
  sources through simple scripting tools by
  combining existing web services into entirely new
  applications
• Typically sourced from a third party via a public
  interface using Web feeds (e.g. RSS or Atom) and
  JavaScript

21
AccuWeather

• AccuWeather
• (Web 2.0) Widget-delivered weather information
  allows our clieants to be more productive in
  utilizing AccuWeather data to identify and
  exploit business opportunities while at the same
  time helping clients manage risks imposed by
  adverse weather conditions.

• Overview
• SMB company that aggregates weather content,
  crushes forecasts that are consume by diverse
  businesses
• ProfessionalPlus staff that assembles custom
  forecast models for businesses
• ModelPlus - suite of advanced forecast modeling
  solutions such as StormTimer
• Example CSX - sends train route information to
  AccuWeather - compares with severe weather to
  message CSX systems of severe, situational
  conditions
• AccuWeather Opportunity
• Backlog of custom dashboards growing fast
• Customers asking for flexible mash-ups to meet
  ongoing changing business needs
• Customize costs high given current technology
  foundation
• Extend current weather content subscription to
  enabling user-customizable dashboards
• Seeing growing number of weather widgets, branded
  with AccuWeather - with poor quality - potential
  reflection on company

22
Porque as empresas precisariam de Web
2.0? Because the Landscape has changed

• Causa
• The World is Flat
• Information Overload
• Business Changes faster than IT can respond
• CIOs cant afford to serve the long tail
• Efeito
• Empowerment and independence of Knowledge worker
  
• Knowledge Worker is now the Situational
  Application Assembler.
• Web 2.0 enables the Knowledge worker to
  collaborate and create good enough solutions
  that satisfy their ever changing needs
• Issues
• Productivity of Knowledge worker Tools for new
  programming models
• Reliability and Manageability of decentralized IT
  applications
• Search capabilities to enable reuse of long-tail
  solutions

Junção dos mundos SOA e Web 2.0

• SOA-class Apps
• Standards-based (WS-,, SCA)
• Normalized Transactions
• Inward-Facing
• Somewhat loosely Coupled
• Security lockdown
• Gartner

• Web 2.0-class Apps
• Web 2.0 technologies services - defacto
  standards
• Content/data focused
• Outward-Facing
• Very Loosely Coupled
• Security Assume Everything is a Threat

28
Reshaping of Enterprise Software
Enterprises Putting Web 2.0 to Work

• Focus on Simplicity - empowering content-centric
  developers
• Data Driven - business value centered on content
• Remixability - new business opportunities to
  COMBINE content
• OpenAPIs - building/extending ecosystems both
  with ISVs customer COLLABORATION
• Rich Internet Applications - improved EXPERIENCE
  leads to improved revenue
• User Generation Content - active participation
  self organization to influence product development

29
Web 2.0 permite criar uma Global SOA
Enterprises are exposing more services and feeds
to the Web and consuming more services and
feeds from the Web

• Exposing Enterprise Services to the Web extends
  your enterprise globally and simplifies
• Development
• Composition of Services
• Deployment and accessibility
• QoS Performance, Scale, Security

SOA e Web 2.0 Mudanças no contexto processos,
tecnologias, skills

• Increasingly, applications will be developed or
  modified in departments and LOBs, not just in IT
  shops
• Situational applications are being developed in
  simple ways (e.g., Web 2.0), and will integrate
  and run across different development environments
  (J2EE, LAMP, .Net, )
• Situational applications will integrate
  components from within the enterprise and from
  the outside (other enterprises, internet)

Therefore, corporate IT will be challenged to
facilitate the development, integration, and
management of situational and enterprise
applications
32
SOA e Web 2.0 Mudanças no contexto processos,
tecnologias, skills
Model

• Gathering business requirements, discovering
  available services and components, and simulating
  the desired business processes

• Compose applications that use services residing
  in different environments using natural metaphors
  (e.g., access EJB or web service from PHP)
• Testing provide the developer with an
  environment that resembles the deployment
  environment (e.g., testing solutions across
  multiple environments)

Assemble
Deploy

• Configure distributed applications so that
  different pieces can run in their associated
  environments
• Coordinate upgrades of dependent pieces across
  heterogeneous environments using a common set of
  tools

Manage

• Facilitate problem determination in a mixed
  environment (e.g., stitching together traces and
  logs from different application environments)
• Autonomic resource management (e.g., tuning and
  load balancing optimized across application
  environments)
