Integration of legacy systems into a modern enterprise SOA (part 8)

Integration of legacy systems into a modern enterprise SOA - Part 8 (last part)

8. Conclusion

The integration into a modern architecture can often be an opportune and flexible alternative to full replacement or redevelopment of an existing legacy system. The advantages of an integration using the SOA approach are:

- preservation of the business logic of the legacy system
- reduction of risk: No expensive and complex replacement or redevelopment necessary
- reduction of TCO
- Usage of the existing modern (SOA-) IT landscape (including infrastructure and hardware)
- guranteed future and flexibility because of standards, frameworks and reference architectures
- modern business processes because of service-oriented architectures and their advantages (loose coupling, reusability, flexibility, interoperability, standardization, less maintanance, ...)

The integration of legacy systems into a modern IT landscape kann be a complex project. Endurance is needed for the development to a flexible and agile company.
