Today's it challenges: Quality Web services and service oriented architectures

The World Wide Web is evolving into a medium providing a wide array of ecommerce, business-to-business, business-to-consumer, and other information-based services. In Service Oriented Architecture (SOA) technology, Web Services are emerging as the enabling technology that bridges decoupled systems across various platforms, programming languages, and applications. The benefits of improving IT services' quality when using Web Services and SOA come at the expense of introducing new level of complexity to the environments where these services are deployed. This complexity is compounded by the freedom to compose Web Services to address requirements such as quality of service (QoS), availability, security, reliability, and cost. Web Services deployed in SOA enable a new paradigm for the design and operation of business applications.
