Abstract

Service orientation is an approach to software systems development that has become a popular way to implement distributed, loosely coupled systems, because it offers such features as standardization, platform independence, well-defined interfaces, and tool support that enables legacy system integration. From a quality attribute point of view, the primary drivers for service orientation adoption are interoperability and modifiability. However, a common misconception is that an architecture that uses a service-oriented approach can achieve these qualities by simply putting together a set of vendor products that provide an infrastructure and then using this infrastructure to expose a set of reusable services to build systems. In reality, there are many architectural decisions that need to be made. An architectural decision that promotes interoperability or modifiability can negatively impact other qualities, such as availability, reliability, security and performance. This presentation will talk about  the effect that service orientation has on system quality attributes.
