Rejuvenate and Modernize your Core Systems with Service Oriented Architecture

Real Life Legacy Modernization

¬ Protects Existing Investments

¬ Quickly Improves Business Efficiency

¬ Increases Application Reach

¬ Reduces Maintenance Burden

Reasons Why Organizations Choose to Modernize

SOA starts with Legacy Modernization

GOVERNANCE

Monolithic applications

Reusable services via Legacy Modernization

Business services via Orchestration

Processes and Web 2.0 applications via Composition

Monitoring and optimization

is now received, processed and

approved within a day

instead of 18 days

What does it do?Enables reuse of legacy functionality to Web services for SOA environments

Benefits:¬ Reuse existing functionality¬ Automate business processes (BPM)¬ Standard-based Integration¬ Ready for SOA governance

Application and Data Integration

What does it do?Merging and integrate data or functionality

Customer Best Practices and Examples

Increase User Productivity with Composite Applications

STUDENT HOME VIEW

The Home Page of the Crossvision

Campus Connect shows real time data

from different sources in one single

composite and contextual view.

Increase User Productivity with Composite ApplicationsADD A COURSE

Adding a Course gives you a view that shows

your current classes and an area where you

can browse courses and view in real time if there is an opening in the course and more detailed information

before applying for it. Class status of being

open or closed will update in realtime.

Increase User Productivity with Composite Applications

ADMIN REPORTS

This is an example of how powerful in

Context applications are in this report. An Administrator will be able filter the Data,

drill in even more and act on it to make a

more informed decision.

Customer Best Practices

¬ Extend and Reuse Legacy Applications and Business Functions as Fine Grained or Business Services

¬ Implement an Enterprise Service Bus (ESB) as the ‘back bone’ of your SOA, to allow services to be loosely coupled and allow for the creation of composite services

¬ Implement a SOA Governance and Management Tool, to allow for management, impact analysis and life-cycle management in the new Architecture

¬ Implement a robust security layer to protect web services, even if they are only deployed internally

¬ Implement Best Practices and Methodologies to ensure reuse of services and to support Business and IT resources
