Ilyas · Jalal S. Alowibdi Received: 9 October 2017 / Accepted: 8 May 2018 © Springer-Verlag GmbH Austria, part of Springer Nature 2018 Abstract We analyzed the performance of a multi-node OpenStack cloud amid dif- ferent types of controlled and self-induced network errors between controller and compute-nodes on the control plane network. These errors included limited band- width, delays and packet losses of varying severity. This study compares the effects of network errors on spawning times of batches of instances created using three different virtualization technologies supported by OpenStack, i.e., Docker containers, Linux containers and KVM virtual machines. We identiﬁed minimum/maximum thresh- olds for bandwidth, delay and packet-loss rates below/beyond which instances fail to launch. To the authors’ best knowledge, this is the ﬁrst comparative measurement study of its kind on OpenStack. The results will be of particular interest to designers and administrators of distributed OpenStack deployments. Keywords OpenStack · Containers · Performance measurement B Muhammad U.
