- Standards and interoperability make SOAs a true option now
- A move to SOA is not a "rip and replace" action—it can be done gradually, and can include existing investments
- An SOA must be inclusive—it must cover the needs of the business, and give capabilities to automate interactions along the value chain
The increased dependency of organisations on the underlying IT and the need to be able to respond more rapidly to changes in the market mean that changes in the way that they implement and manage the underlying IT infrastructure may be needed. No longer can "solutions" be put in place to specific issues - at all times, interoperability and technical flexibility must be borne in mind, so that business issues, predicated on business processes, can be dealt with in the round. However, the existing investments in technology cannot be written off, and an organisation must look to how these can be included in the new environment. To this end, companies must prepare for SOAs, putting in place an environment that has the inherent flexibility and standards support to include existing investments, and to embrace emerging solutions.
It is Quocirca's view that this platform must address the needs of not only the main users within the organisation, but also the needs of the company looking up and down the value chain, thus supporting the business' processes from end to end. Quocirca's view is that attempting to do this through an application-centric approach may lead to an over-dependence on the application vendor, and that the lack of ISV in areas two or more steps removed from the ISV's core competencies can create the need for hard-coded connectors that may further compromise the flexibility of the company. Therefore, Quocirca's main recommendations when looking for a suitable solution are that the following capabilities be demanded from the vendor:
- Solid ISV and system integrator support
- Full Web Services (WS-*) standards support
- A fully SOA, based on integrated yet independent service components
- Capability to support loose coupling of services
- The provision of a bus architecture including data transposition, translation and transport capabilities
