“Measure and benchmark reliability of your OpenStack virtual machines.” “VM Reliability Tester” is a software that tests performance and reliability of virtual machines that are hosted in an OpenStack cloud platform. It evaluates the failure rate of VMs by performing a stress test on them. VM Reliability Tester installs OpenStack virtual machines, uploads a test […]
After having completed part 1 of our series about reliability analysis, we now start with our first reliability measurement experiment. According to reliabili theory there are three things we could measure: survival probability, hazard rate and failure rate. The last one is the easiest one in practice. Therefore we design an experiment to measure the […]
In the previous article we defined use cases for an OpenStack implementation according to the usage scenario in which the OpenStack environment is deployed. In this part of the Dependability Modeling article series we will show how these use cases relate to functions and services provided by the OpenStack environment and create a set of dependabilities between use cases, functions, services and system components. From this set we will draw the dependency graph and make the impact of component outages computable.
