Web services play a crucial role in enabling reliable communication across extensive geographic areas. Although the Internet serves as a viable platform for this communication, it is imperative that these web services fulfill specific criteria to ensure their effectiveness and trustworthiness. Key requirements include robust security measures to protect data and transactions, high availability to ensure that services are accessible when needed, reliability to guarantee consistent performance, and the capability for scalability to accommodate varying loads and user demands. Moreover, these web services should be designed to seamlessly integrate with existing communication infrastructures at the endpoints. This facilitates smooth operations and reduces the complexity of deployment in diverse environments. In this paper, we will delve into the application of web services that are built upon the OPC Unified Architecture, examining their potential to meet these essential requirements while enhancing interoperability and efficiency in communication networks.
