Resource Management in Cloud Computing is a topic that has received much interest both within the research community and within the operations of the large cloud providers; naturally, as it has a significant impact on the cloud provider’s bottom line. Much of the work to date on resource management focuses on Service Level Agreements (for […]
Energy in general and energy consumption in particular is a major issue for the large cloud providers today. Smaller cloud providers – both private and public – also have an interest in reducing their energy consumption, although it is often not their most important concern. With increasing competition and decreasing margins in the IaaS sector, […]
The Green IT Special Interest Group (SIG) of the Swiss Informatics Society met yesterday (29/10/14) in Zurich. ZKB kindly hosted the event. A full meeting report will probably appear on the group’s website, but here we just capture some of our reflections on the group’s work. This was our second time to attend the group […]
In some of our project work, we need to understand the energy consumption of our servers. One basic test we performed was to determine how server power consumption increases with load. In this blog post we document the results we obtained. Schlagwörter: cpu bound workload, server energy consumption
We’ve given some impressions of IEEE Cloud over the last couple of days. The final day definitely had less energy with some no-shows for presentations and the audiences being generally small – getting to/from Alaska is not so easy so I guess some folks are already on their way home. That said, there were a […]
In yesterday’s post, we gave an initial feeling of IEEE Cloud. This is a follow up which highlights some of the activity on July 1. Schlagwörter: conferences, IEEE, ieee cloud
This year was our first attendance at IEEE Cloud. We did not really know what to expect. This is the first of 2-3 posts which capture some of what went on at the conference. Schlagwörter: conferences, IEEE, ieee cloud
The release of Icehouse brought a few enhancements that were of particular interest in our work – notably Ceilometer/Telemetry developments both in terms of data models as well as performance and improved support for live VM migration. As we had a positive experience with installing Openstack using Mirantis Openstack 4.x (based on Fuel 4.x), we thought […]
ICCLab attended the OpenCloudDay in Bern en masse. Being one of the most known (infamous?) cloud computing groups in Switzerland, we had to show our strength at one of Switzerland’s most prestigious cloud events!

Update: This does not apply to Icehouse. This flag was to activate an experimental feature -this option no longer exists in Icehouse. (It is in Havana, however). There have been some criticisms of the implementation of Ceilometer (or Telemetry as of Icehouse) – however, it’s still the main show in town for understanding what’s going […]
