A Blog of the ZHAW Zurich University of Applied Sciences
In a previous series of blog posts (1, 2, 3), we have discussed how to install Monasca to monitor OpenStack, how to create alarms based on specific events happening in the monitored system, and how to setup notifications when any of these alarms are triggered. Going further, in the context of the Cloud Orchestration initiative and the Hurtle […]
In the GEYSER project, we are examining suitable Openstack architectures for our pilot deployments. In an earlier blog post we described different ways to architect an Openstack deployment mostly focusing on AZ (Availability Zone) and Cells (those were the only options available back in 2013). Much has changed since then and new concepts were added […]
Up to now, we have published several blog posts focusing on the live migration performance in our experimental Openstack deployment – performance analysis of post-copy live migration in Openstack and an analysis of the performance of live migration in Openstack. While we analyzed the live migration behaviour using different live migration algorithms (read our previous blog posts regarding pre-copy […]
The Problem Cloud networking bases on tech and protocols that were not initially designed for it. This has lead to unnecessary overhead and complexity in all phases of a cloud service. Tunneling protocols generate inherent cascading and encapsulation especially in multi tenant systems. The problem increases by vendor specific configuration requirements and heterogenous architectures. This complexity […]
As part of our on-going work in MobileCloud Networking the project demonstrated at this year’s EUCNC, held in a very warm (> 35*C !!!) Paris, France. The MCN demonstration was built on top of a standard cloud infrastructure, leveraging key technologies of OpenStack and OpenShift and used (open source outputs of MCN, namely hurtle – […]
The 4th Open Cloud Day, which we co-organised with The Swiss Open Users Group (/ch/open), took place earlier this week. The event held a gathering of about 120 participants, from industry and academia together. There were in total 17 talks and 3 workshop sessions.

“The autoscaling cloud monitoring system that requires no manual reconfiguration” “Nagios OS autoconfigurator” (N_O_conf) is a cloud monitoring system that automatically adapts its monitoring behavior to the current user-initiated VM infrastructure. N_O_conf works by installing a cloud environment change listener daemon which is repeatedly polling the OpenStack API for changes in the VM infrastructure. As […]
“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 […]
Last evening, we had our 10th OpenStack Switzerland User Group Meetup. The nice folks at Puzzle ITC hosted and sponsored the event in their premises. The meetup started with a warm welcome from Mr. Mark Waber, CEO of Puzzle ITC and our own Mr. Andy Edmonds, Senior Researcher in the lab. We quickly moved on […]
[Note: This blog post was originally published on the XiFi blog here.] One of the main jobs performed by the Infrastructures in XiFi is to manage quotas: the resources available are not infinite and consequently resource management is necessary. In Openstack this is done through quotas. Here we discuss how we work with them in Openstack. Schlagwörter: […]
