(CAG 14)Version 01

© Copyright 2008 Wipro Technologies

Agenda

18:00-18:05 Introduction

Participant Introductions

Recap of the Purpose for the CAG

18:05-18:25 Share the finding on the Challenges

Findings from the Discussions on Challenges

Potential Roadmap – Work in progress

Intro to the IntegrateIT - ROI Calculator – Work in Progress

18:25-19:00 Questions and Discuss


Reasons for Customer’s turning to Integration

Complex heterogeneity Fragmented, Siloed, non Integrated, Diverse and Inflexible processes More of Point-to-Point Connections/ legacy style integrations with no clear

middleware strategy Diverse options for technical connectivity Handling requirements around semantic integration

Reduced business agility Lack of near real time visibility into automated IT systems Long development cycles in hooking up to value networks Recurring themes, but low re-use when developing new composites No flexible Business Processes/Integration Strategy

High Operational Costs Multiple point to point connections Multiple interfaces to build, operate and upgrade Multiple Skills – SPOF risk, lack of personnel Performance, QoS Problems - when current EAI connects to SAP system No reusability Huge investments in Best of Breeds (Non SAP) & Legacies


Legacy Solution - Approaches

Core Approaches for Integration

File Transfer

Shared Database

Remote Procedural Calls

Messaging


Customer Dilemma

Problem Definition “: EAI tool turned Legacy – What are my risks”

Sell it “: How does ROI Calculator for my Middleware Replacement Look like”


Define the Top Challenges with Legacy Integration Solutions

Proper Functioning of the Integration Solution - Issues

Capability of the Middleware to overcome the limitations of the Participating applications

Lack of interoperability among Standard compliant products eg: CORBA

Support for XML doesn’t automatically result in support for Semantic interoperability

Lack of Scalability

Lack of Loose Coupling

Lack of Effective Systems Management function – Governance Process & Tools

Too many technologies enabling the integration become maintenance bottleneck

Lack of Support from the Integration Vendor/Vendor Viability

EAI Solution not strategic to Corporate Systemizing goals


Initial Pilots

Potential Migration Roadmap

Legacy Solution

SAP PI Solution

Partially Migrated Solution

Co-Existence Solution

• Clearly define POC domain

•Consolidate the Service Interfaces

• Initial Costs

• Customization

• Maintenance

• Changes

•Identify Internal interfaces• Identify B2B Interfaces• Security Issues• Test and Evaluate


Partial Migrated Solution – CoExistence Context

Recommendation :

• Focus on a Balanced Approachto Integration

• Ensure proper requirement analysis and incorporate good change management processes to avoid “Over Integrate” mentality (This can be done on a proto type during pilot phase to avoid risk of lack clarity around future requirements)

Migration Activities

• Change to Legacy Apps

• New Integration logic for present integration

• Configure/Implement PI System
