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

During his travel in USA, in Jun 2014, the researcher Antonio Cimmino (Zurich University of Applied Science, ICCLab) had the opportunity to visit the MIT SENSEable City Lab, in Cambridge Massachusetts USA, invited by the Director Dr. Carlo Ratti. The SENSEable City Lab is radically transforming the way the cities are described and understood; alongside […]
Introduction Many large enterprise applications rely heavily on the underlying information stored in databases. Most of these are used every day via the web browser by hundreds of users, or run calculations in a batch mode. These actions are database intensive. As long as each resource is on premise, communication speed to those databases is […]

We are changing our ceilometer backend from mysql to mongodb in one of our experimental Openstack installations. The reason for this change is that mongo seems to deliver better ceilometer performance than mysql; further ceilometer data structures are a more natural fit with mongo (and indeed, this is largely where they came from). This can […]
Ongoing adoption of Cloud Computing has lead to an increase in the level of complexity of the existing services and inherently increasing risks for companies willing to migrate in order to benefit from this new paradigm. Unfortunately, one area that has not been properly engaged is Incident Management. Cloud Incident Management is a new research […]
We are working on upgrading some of our servers from Havana to Icehouse. One of the reasons for doing this is that the performance of Ceilometer on Havana is underwhelming. Part of the move involves moving to a mongodb backend (default in Mirantis Openstack 5.0) but we also want to keep our energy consumption data […]
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 […]
