The last decade has seen a widespread adoption of web-services as the medium for platform-independent and language-neutral communication amongst applications over the web (Park et al. In the present day an increasing number of businesses are planning to developing future solutions that leverage the Web-Service technology.

Various low-level mechanisms can be used to aid this, including locks, semaphores, mutexes and queues.

Resource management for dynamic, distributed real-time systems requires handling of unknown arrival rates for data and events; additional desiderata include: accommodation of heterogeneous resources, high resource utilization, and guarantees of real-time quality-of-service (Qo S).

Members of the research community argue that the success of critical business applications highly depends on the selection of Web-services that meet certain Quality of Service (Qo S) properties (Shao et al. The current web-services architecture is based on three main entities as described by Ambrosi et al.

(2005) in [18]: Service Providers: They develop web-services, publishing their web-service descriptions (in the form of a WSDL file) with registries and deal with requestor invocations of the web service.

Predicting the task execution times has been studied in grid and distributed computing contexts with different objectives and assumptions. The specific contributions of this paper are: Qo S monitoring and resource usage profiling; prediction of real-time Qo S (via interpolation and extrapolation of execution times) for heterogeneous resource platforms and dynamic real-time environments; and resource contention analysis. This paper describes the techniques employed by a resource manager that addresses these issues.The specific contributions of this paper are: Qo S monitoring and resource usage profiling; prediction of real-time Qo S (via interpolation and extrapolation of execution times) for heterogeneous resource platforms and dynamic real-time environments; and resource contention analysis.Lecture notes in computer science ISSN 0302-9743 Congrès Parallel and distributed processing : ( Cancun, 1- ) 15 IPDPS 2000 workshops, Cancun , MEXIQUE (01/05/2000) 2000 , vol.
