The convergence between Web services and grid computing became possible the integration of distributed services, providing the use of sharing and coordinated resources on the network. In this environment, the purpose of a Metascheduler would improve the performance, availability and scalability of the resources. In this paper, we present a Metascheduler framework aiming QoS provision in Web services executed on a grid environment. The Metascheduler will be responsible for jobs submission and for managing of resources on the grid, and also to select the best available resources pool for implementation of the task sent by the user. To achieve this goal, the Metascheduler deals with the priorities that are generated according to the agreement time, addressing the service level agreement (SLA) stipulated. The contracts in the SLA are adjusted dynamically. Thus, the virtual organization (VO) which provides more cycles of processing time will be one that holds the highest priority when making a service request.
