Service oriented architecture

An Autonomic Service Oriented Architecture in Computational Engineering Framework

Service Oriented Architecture (SOA) technology enables composition of large and complex computational units out of the available atomic services. Implementation of SOA brings about challenges which include service discovery, service interaction, service composition, robustness, quality of service, security, etc. These challenges are mainly due to the dynamic nature of SOA. SOAmay often need to ...

Service Oriented Security Architecture

As Service Oriented Architectures (SOA) and Web services are becoming widely deployed, the problematic of security is far from being solved. In an attempt to address this issue, the industry proposed several extensions to the SOAP protocol that currently reached different levels of standardization. However, no architectural guidelines have yet been proposed. In this paper we first outline the s...

Service-Oriented Architecture

In service oriented systems, Quality of Service (QoS) is a service selection driver. Users evaluate QoS at run time to address their service invocation to the most suitable provider. Thus, QoS has a direct impact on providers' revenues. However, QoS requirements are difficult to satisfy because of the high variability of Internet workloads. Workload variability cannot be accommodated with tradi...
