Abstract:
Simulating modern cloud systems requires tools that balance precision, extensibility, and reproducibility. Existing simulators often target specific use cases or rely on monolithic designs, which hinder the integration of alternative models for workload generation, resource allocation, or cost estimation. We present a modular and reproducible architecture for a cloud simulation framework, implemented in a functional prototype, and designed to support composable experimentation through a plugin-based approach. Simulation scenarios are defined declaratively, specifying interchangeable components, such as allocators, load balancers, workload injectors, and cost models. This architecture enables the systematic exploration and evaluation of diverse cloud management strategies, offering full support for event traceability, component reuse, and seamless integration into scientific workflows.
