Abstract

This demo showcases an open-source simulator for evaluating the performance of cloud-native applications in Cyber-Physical clouds. Applications are modelled as DAGs of possibly stateful microservices, each implemented as a pool of load-balanced, distributed containers which can be subjected to different kinds of random failures. Such applications are simulated as DAGs of special FIFO queues to capture statistics such as nodes utilizations, end-to-end latency distributions, and other relevant metrics via discrete event simulation. This allows users to evaluate the performance impact of e.g. different load-balancing strategies, fail-over techniques or state management policies. In this demo, we will introduce the audience to the simulator through some simple but significant examples, showing how to use it to identify performance bottlenecks in a cloud-native application and how to correctly configure a Cyber-Physical cloud to serve it.
