A Compendium on Service Oriented Architecture and Service Level Agreements

Service-Level Agreements for Service-Oriented Computing

Service-oriented computing is dynamic. There may be many possible service instances available for binding, leading to uncertainty about where service requests will execute. We present a novel Markovian process calculus which allows the formal expression of uncertainty about binding as found in service-oriented computing. We show how to compute meaningful quantitative information about the quali...

Service-oriented high level architecture

Recently, service-oriented paradigm is emerging as a new pattern following process-oriented and object-oriented ones in systems analysis and software development. Service-oriented High Level Architecture (SOHLA) refers to the high level architecture (HLA) enabled by Service-Oriented Architecture (SOA) and Web Services etc. techniques which supports distributed interoperating services. The detai...

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 ...

Web Service Providers\' Game on Price and Service Level

  Response time is one of the critical web service quality dimensions. It refers to how long it takes that a web service responds to request of a user. In order to manage the response time, pricing schemes can work as an efficient access control mechanism. In this paper, we study competition between two providers offering functionally same web services where there is a monopoly service provider...
