Abstract :
Developing IT systems to satisfy Service Level Objectives (SLOs) of various Non-Functional Requirements (NFRs) while minimizing cost is in great demand. To automatically find the best system design, we propose an effective optimization method based on models of IT systems and their NFR evaluations. Our method is able to handle SLOs whose satisfaction is hard to check analytically as constraints and can be applied to a wide variety of system sizing problems.
