In this paper, we discuss a Real-Time Calculusbased approach for the performance evaluation of multi-tier cloud applications. We focus on its capabilities for estimating the Quality of Service parameters.
Analytic models allow the performance evaluation of proposed system changes without requiring complex and expensive detailed simulations. In this paper, Real-Time Calculus (RTC), a high-level analysis technique previously proposed for stream-processing hard real-time systems and frequently used to evaluate trade-offs in packet stream processing architectures, has been applied to analyse the behaviour...
In this paper we compare an analytical framework based on Real-Time Calculus with the existing analytical approaches commonly used for the performance evaluation of network interfaces such as probabilistic queuing models, parallel computation model, and protocol offload models (LAWS and EMO). In particular, we focus on the capabilities of these alternatives that can be employed for the performance...
