SOA Concepts Getting Started with SOA using OpenEdge Examples


What is SOA?

A software systems architectural style

An approach for building agile and flexible business applications, based on services

Loosely coupled services = flexible business processes

Service-Oriented Architecture


GET OUT OF MY KITCHEN!

Real-World Service Example


Service Provider

Accomplishes a defined, self-containedunit of work • Does not depend on the state

of other processes/functions Internal details hidden

• Programming language• Execution logic• Data store (if any)

The service, exposed using a service interface, is stable and built to last

Service ImplementationService Implementation

Logic

Service Interface


Service Contract

Service provider defines the available service operations• Input & output information

supported by each operation• Data representation model for

each parameter Rules and/or policies for using

the service Quality of Service (QoS)

attributes


Service Requester

Presentation (UI) layer or another service Locates service provider through agreed-upon

service directory Binds/invokes a service

based on a service contract Service adapter encapsulates

all issues associated with accessing the service

SOA: Just Service Providers & Requesters?

How do you:• SOA-enable existing

applications?

• Mediate service interactions?

• Compose and reuse service capabilities?

Don’t forget about Distribution, Scalability, Reliability and Security!

Agenda

SOA Concepts Getting Started With SOA using OpenEdge Examples


Getting Started with SOA:Pilot Project Example

Situation• Specialized lighting manufacturer• 27 corporate divisions: no common integration• Re-use mix of OpenEdge and other solutions

Pilot project: start small and build on success• Deliver part diagrams electronically

Next look outward: invoicing service• Suppliers send invoices to a service• Correlate purchase orders & receipts to

invoices


SOA to Increase Business Example

Situation• Financial services company with 250K

customers and 20K transactions/day

• Goal: customer/revenue growth through superior on-line banking & call center

• Lacked integration across 8 backend systems and 2 external partners

Layered architectural and services approach• Started with internal processes first

Results

Lowered development time 40% and cost 50%• Now have the ability to change business logic

independent of other layers

Successfully managing 1M+ messages / day 50% increase in on-line customers in first 6 months Improved customer service while reducing costs The technology is very exciting, but…

• Stay focused on reusable business logic

• Do not add complexity if it is not needed


Establishing New Sales Channels Example

Situation• $40M company shipping 6,000 packages/day• Goal: common infrastructure for the print catalog,

online and retail store sales channels• Phase 1: Catalog system to make order fulfillment

Followed the SOA pattern:• Reusable OpenEdge components for common

activities, e.g. tax calculations• Messaging replaces batch• Integrated to backend systems (e.g. AS400, Unisys)

without application code changes• ESB validates and transforms data


Results

Only 6 months from initial design to deployment!• System is extremely stable

Flexible business processes without coding changes

Near real time processing as compared to batch


In Summary

SOA is the architecture for the agile business• A design approach, not a

technology

OERA provides a framework Progress Software supplies the

technologies you need to achieve your SOA
