Seminar Service-Oriented Software Systems

Dr. Serge Shumilov

The rationale of a service-oriented architecture (SOA) is to encapsulate local resources (e.g. legacy applications, databases, or hardware cycles) as a service and to make them localizable and accessible in a local or global network. Recent implementations of service-oriented architectures are nowadays based on the Web services “stack” provided by the W3C. This stack features a set of standardized protocols (e.g. SOAP) as well as notations for describing services (e.g. WSDL) and for composing the same (e.g. BPEL). Both protocols and notations are based on the meta-language XML. The adoption of these well-established standards increases remarkably the degree of interoperability between different services. To date, the most dominant application field of Web services is the integration of various applications within an enterprise towards a coherent, workflow-based application (EAI = Enterprise Application Integration). New application fields arise from scientific application scenarios, in which extensive computations are executed and scheduled on many different network nodes This application field refers to Grid Computing.

The goal of this seminar is to provide an overview of state-of-the-art topics around SOA. Possible topics are (but are not limited to):

o System Patterns for SOA

o Grid Architectures (Grid vs. P2P vs. WebServices, Grid Databases)

o Workflows in Grid (description languages, distributed execution)

o Centralized vs. decentralized coordination of resources

o Semantic Grid

o Security Aspects

The participants of the seminar are first asked to prepare a seminar paper (approx. 15 pages) for a selected topic. The relevant aspects of a paper are presented in a presentation that takes approx. 45 minutes following a discussion. A certification for this seminar can be acquired, if both the seminar paper and the presentation satisfy highly scientific demands.
