O Fenômeno Wikipedia

Imaginem um projeto com as seguintes características:

– Aglutinar todo conhecimento humano

– Autoria colaborativa

– Dezenas de línguas (+1.500.000 verbetes em inglês e + 230.000 em português)

– Manter histórico das atualizações, acesso rápido, flexível nas atualizações e inserções de verbetes (1500 verbetes por dia), alta demanda (um dos dez sites mais visitados)

– Como gerenciar este projeto na forma tradicional?

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.

O que é a Web 2.0?

Web 2.0 is about connecting people, and making technology efficient for people.

Web 1.0 was about connecting computers and making technology more efficient for computers.

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

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 IM AR

The Accelerating Evolution of Software

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

Situational application development paradigms are emerging which will challenge traditional IT development

Mashups like Coffee integrate disparate data sources through simple scripting tools by combining existing web services into entirely new applications

AccuWeather™

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

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.”

Business Changes faster than IT can respond

Knowledge Worker is now the Situational Application Assembler.

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

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

Traditional (Transactional)

Structured design and programming

Code Review

Function test

Quality test

Performance test

Handful of large applications on 100s of machines

Often dedicated – several machines per application

Careful, formal change management

Slowly evolving applications

Changes are major

Situational (Collaborative)

Unstructured programming

Little discipline

No formal test process – using the application is test

Thousands of small applications on handful of machines

Each machine has hundreds of applications

Change management is a huge challenge

Rapidly changing applications

Changes generally minor

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

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)

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)

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
