Last week, 16 Oct 2014, great participation to OpenStack User Group – Meeting @ICCLab Winterthur. We have co-located it with docker CH meetup. Around 60 participants from both the user groups. For this event, we have organised the agenda trying to have a good mix of big players and developers presentations. Goals : Analysis […]
What is it all about? We’re using a bunch of VMs to do numerical dosimetry and are very satisfied with the service and performance we get. Here I try to give some background on our work. Assume yourself sitting in the dentists chair for an x-ray image of your teeth. How much radiation will miss […]
The icclab participated on the Nagios World Conference 2014 which took place Oct 13th-16th, 2014 in St. Paul, MN, USA. Icclab’s Cloud High Availability-initiative leader Konstantin Benz presented an approach on how to use Nagios Core to monitor utilization of OpenStack resources. The key point he mentioned was that Nagios has to be reconfigured elastically […]
In our previous work we presented the performance of live migration in Openstack Icehouse using various types of VM flavors, its memory load and also examined how it performs in network and CPU loaded environment (see our previous posts –performance of live migration, performance of block live migration, performance of both under varying cpu and […]

In one of our projects we need to understand the energy consumption of our servers. Our initial work in this direction involved collecting energy consumption data using Kwapi and storing it in Ceilometer for further study. The data stored in Ceilometer is valuable; however, it is insufficient to really understand energy consumption in detail. Consequently, […]
Previously, we analyzed the performance of virtual machine (VM) live migration in different scenarios under Openstack Icehouse. Until now, all our experiments were performed on essentially unloaded servers – clearly, this means that the results are not so widely applicable. Here, we analyze how the addition of load to the physical hosts and the network […]
We continue our recent work regarding an analysis of the performance of live migration in Openstack Icehouse. Our previous results focused on block live migration in Openstack, without shared storage configured between computing nodes. In this post we focus on the performance of live migration in the system with a shared file system configured, compare […]
Join us at the second CloudFoundry User Group DACH Meetup on September 22nd in Zürich. This time the focus is on CloudFoundry in general. Learn about the basic functionality in the CloudFoundry 101 session and pick up some lessons learned from Klimpr, a startup which switched its Application from Heroku to CloudFoundry. Date & Time Monday, September 22nd 2014, 18:00 CEST Place […]
We prepared this blog post to help students understand the hypervisor-support matrix introduced by OpenStack . This information is spread throughout different sources. Many of these include Redhat Linux and OpenStack. We have tried to provide more general explanation where possible and reference links to other relevant sources. The respective features’ command syntax are of course different for different cloud platforms. This information is […]
