Open Source SOA Benifits

The benefits of the service-oriented architecture are widely touted: reduced integration costs, greater asset reuse, and the ability for IT to respond more quickly to changing business and regulatory requirements. But what about the pitfalls?

SOA pioneers know all too well the challenges that can arise when a company service-enables critical applications. The SOA endeavor spans IT disciplines: It’s part systems design and architecture overhaul, part application development and business makeover. Here, early adopters and other experts give their best advice about avoiding the obstacles when building this New Data Center essential, the SOA.

SOA requires the integration of many varied processes, applications and technologies that are difficult to mesh seamlessly, meaning incompatibility, scalability and flexibility issues often arise. The license-fee structure of traditional software can also limit options and add cost. Turning to open source technology can help alleviate these issues and accelerate deployment, as well as business adoption.

Open source has become a staple of enterprise-class IT as concerns about stability, security and support fall away. Open source is as stable, secure and well supported as proprietary solutions, if not more so. In addition open source SOA solutions provide:

• Simplicity – Open source solutions are easy to find and easy to implement, with many architects and developers being familiar with the core mechanics of the technology. Open source developers are motivated by their communities to deliver easy-to-use frameworks and platforms. It also enables enterprises to rapidly create solutions to deliver tangible, measurable benefits.

• Openness – The flexibility inherent in open source allows for more freedom and personalization of the solution than proprietary offerings, and means that an organization will see more value relevant to its operations from the installation.

• Affordability – The open source subscription model makes SOA products less expensive than proprietary tool sets.

The benefits of open source SOA solutions can be realized in each of the six stages of the SOA evolution:

1) business process understanding;

2) IT assessment;

3) SOA design/determination;

4) SOA service enablement;

5) SOA integration and governance infrastructure;

and

6) process orchestration/composition.

For the first three steps, work efforts are focused on the business processes, current IT design and SOA design, and the open source subscription model offers a more affordable and flexible pricing structure than traditional SOA solutions. That helps the SOA design work proceed more quickly without concern about per-CPU license fees.

The advantages of open source solutions are particularly evident during the final three steps in the process.
