The primary issue that needs to be considered when implementing a SOA is that the entire organization is on board. If some parts of your organization are implementing an SOA and others have not bought into it, you will end up with similar issues as exist when an SOA is not implemented at all. Educating the entire organization in relation to why a SOA is being implemented and the benefits it can bring is the first key issue.
The second key issue comes down to the technology choices that will be made. There are many technologies available that tell you that they ‘do’ SOA, however, many still tie you into proprietary interfaces and technologies. Implementing a standards based SOA by choosing technologies that use standards like SOAP, REST, UDDI etc. can provide additional benefits:
- You are free to choose best of breed technologies that support the standards that you will use for each different service.
- You could potentially use different technologies that implement the same standards. While this may sound strange, one product may offer advantages in terms of cost or levels of support for different services that are implemented.
- In many cases, these technologies will be licensed based on how much you use them. This means that their cost is an operational cost as against more traditional models which require investment of significant capital up front.
Finally starting with a small effort can help you to develop implementation processes for your organization in a practical way thus helping you to improve your planning and delivering what your users want on time and within budget. The SOA Gateway provides the perfect tool to investigate how implementing a SOA may help in your organization.
