Agenda

• Mashup• Mashup & SOA in Enterprise

– Promises– Convergences – Challenges

• Personalized Declarative Mashup

with SOA

4

Mashup

5

What is Mashup ?• Mashup - “application that

seamlessly combines content from more than one source”

• Mashup – “interactive , personalized information source from variety of data sources”

• Mashup – “a flexible composition of Services within a rich user interface environment” [ source zapthink ]

6

Consumer Mashup Example

• Housing Maps

– www.housingmaps.com : Mashup of Google Maps and rental data from craigslist

• Chicago Crime

– www.chicagocrime.org : Mashup of Google Maps and Chicago crime statistics

Mashup & SOA in Enterprise

8

Mashup in Enterprise• Simple Services, Loosely Joined

– Unintended Usage

– Situational

• Combines data/content across enterprise

– Different Technologies, Applications, Legacy systems

– BI/BAM, Enterprise Search, Document Repository

– Internal Services

• Mixed with External services

9

Promises

• Empowerment of Business Users - Innovation at user level

• Satisfying short-term needs and niche requirements

• Improvement of ROI by shortening the development life cycle

10

Mashup and SOA Enabled Enterprise

• SOA is now matured enough technology

• Mashup technology can fuel the faster ROI through situational application and BPM 2.0

• SOA can provide the required framework for mashup in enterprise context

• Mashup delivers the promise of SOA for ubiquitous availability of enterprise information

11

Enterprise Usecase for Mashup

12

Usecase

• Extended competitive analysis usecase for “Audi”

– The competitive analysis reports need to be published in feeds or widget in iPhone

– Product requirement database need to be automatically updated

– A feature planning process need to be started for some competitive features

13

Problem Dimensions

• “Situational” integrations – no long term value to the user or enterprise

• Decentralization of IT environment or self-service enterprise – users are empowered

14

Problem Dimensions (contd. )• Simple and non-

programming Integration – business users are not JavaScript or Ajax geeks

• Integration endpoints should be present with std. interface

• Integration of personal content and enterprise systems – spreadsheet with enterprise sales system

15

Challenges

16

Challenges

• Delivery mechanism

– User‘s Desktop

– User‘s smart mobile device [ i.e. iPhone ]

• Sharing & Discovery

• Support

– Support of unknown applications developed by unknown users

– Scalabilty and Availability

17

Challenges

• Quality control

• Governance/Version Management

• Security

– Access management

– Identity propagation across various applications

• Technology maturity - Vendor support

18

Personalized Declarative Mashup with SOA Infrastructure

19

Source of Mashup – SOA based SOBA

• Service Oriented Business Application

– Gartner Term coined in 2004

– Exposes enterprise business information source or applications

• Help focusing on business process

• Alternative approach

– JavaScript/JSON

– RSS

– JackBe’s MashupLet

20

Declarative Mashup

• Declarative ways of service composition made SOA popular in enterprise

• Declarative mashup

– Rules

• Extraction

• Aggregation

• Transformation

• Filtering

– Allow Hybrid-Techies to create mashup [ WSJ ]

21

Declaration Rules• Different ways of declarations

– Functional Programming Approach – i.e. Intel’s Mash Maker

– Procedural Approach – i.e. Yahoo Pipes

– Wiki Approach – i.e. IBM’s QedWiki

– Proprietary Language Approach – i.e. JackBe’s JMML/JUMP

– so on …

22

Declaration Rule UI

• A RIA or widget based rule composer

– Google’s Mashup Editor

– JackBe’s Wire

– SmartPhone based mobile widget platform

– etc…

23

Personalized Mashup

• User empowerment is key

• Personal data also can be mashed up with enterprise information sources

• Social Networking - Tag cloud , sharing mashup script or services

• Inventory of mashups

24

Mashup Platform

• Existing Enterprise SOA platform

• Use of SOBA for enterprise sources

• Declarative - Rule based no coding

• Personalized – By/For/Of User

25

HighLevel Architecture

Mashup Framework

•User defined rule based service composition•Availability and scalability by dynamic service lookup and load-balancing•Enterprise Security policy management•Allow composition rule sharing between users•Service tagging for reuse and collaboration

Solutions

• Delivery mechanism - SOA based SOBA

• Support

– Support of unknown applications - Community

– Scalabilty and Availability - Grid [MashupGrid !!!]

27

Solutions ( contd )

• Quality control - Loose coupling

• Governance/Version Management - SOA Governance policy

• Sharing & Discovery - Community , sharing

• Security - WS-Secutiry , WS-Federation

• Technology maturity – Many vandors

28

Summary

• Mashup in enterprise is reality

• Mashup is disruptive force for Enterprise IT delivery mechanism

• Mashup can realize the ROI for SOA enabled enterprise faster

• SOA - the much required platform for mashup in enterprise

• Personalization and declarative solution can accelarate the adoption of mashup in enterprise

Mashup Patterns in Enterprise

• Content/Data Aggregation

– ~ Portals

– Author : Pure business users

• Guided Interactions

– ~ SOA Composite Apps with BPM

– Author : IT

• Unguided/Adhoc Interactions

– ~ Situational Application

– Author : (Hybrid) Business Users

34

Content/Data Aggregation - Portal

• Enterprise data content aggregation

• Usage of JSR 168/286 & WSRP

• Usage of SOA/SOBA for data source

35

Guided Mashups - BPM 2.0

• (More) External Services Oriented

– REST/RSS in addition to WS-*

– Both Consume & Expose

• Being aware of social software

– Tie in with workspace, wikis, forums, calendar

• Rich & Simple Interfaces

– Web based Process Modelling , Message mediation

36

Unguided Mashup - Situational Applications

• Ad Hoc

– Targets certain situation / subset of users - May not need it for ever but NOW !

• Low Barriers to Building

– Simpler & Richer UI

• Self Service IT - Tackles the Enterprise IT Backlog

– Rise of Hybrid Techie

37

SOA Benefits• Reduced integration costs

• Reuse of business applications

– Legacy application

– New application

– Composite application

• Loose coupling – business agility

• Governance & regulation

– De-centralizing IT

38

SOA Enabled Enterprise

• Abstraction of existing capabilities

• Better IT governance

• Result – Connected , Loosely coupled Applications
