In a service oriented environment an application is created through the composition of different service components. In this paper, we investigate the problem of application admission control in a service oriented environment. We propose an admission control system that makes admission decisions using an online optimization approach. The core part of the proposed system is an online optimization algorithm that solves a binary integer programming problem which we formulate in this paper. An online optimizer maximizes the system revenue given the system's available resources as well as the system's previous commitments. Another part of the proposed system carries out a feasibility evaluation that is intended to guarantee an agreed level of probability of success for each admitted application instance. We use simulations and performance comparisons to show that the proposed application admission control system can improve the system revenue while guaranteeing the required level of quality of service.
