Abstract
The emergence of modern network-centric programmatic paradigms and architectures have made possible the migration of legacy systems as Web Services in distributed networked environments. In this context, legacy systems or other legacy reusable assets can be described, published, located, and invoked in a transparent way. Generally, Service-Oriented Architectures (SOA) can be viewed from the perspectives of three distinct stakeholders namely, the service provider, the infrastructure developer, and the application developer. Each stakeholder has a distinct set of needs and requirements. There are also three basic operations related to the deployment of Web Services; publish, find and bind. Web Services focus on addressing integration and infrastructure complexities by leveraging the benefits of Web service technologies, internet standards and common infrastructures.
