On 9th of March, we organised the 12th OpenStack meetup. A big shout out to Red Hat Zurich who sponsored the event. They also provided the location, at Neue Borse Zurich. As past OpenStack meetups, we had 6 talks again. Schlagwörter: events, meetups, openstack, technical event
Nova manages all compute resources in OpenStack. Today, the Cyclops team is announcing support for compute events such as VM Creation, Deletion, and Modification for billing purposes in Cyclops. All this by directly tapping into the OpenStack message bus for processing critical events in real-time. Schlagwörter: billing, charging, Cyclops, events, nova, openstack, RabbitMQ, rating
The Cyclops team at SE research group in InIT is pleased to announce their upcoming talk at OpenStack CEE Day 2016. Cyclops is undergoing development at breakneck speed and many improvements have been incorporated in the framework in last 6 months. Interested? Then hear us out in Budapest on June 06, 2016. Schlagwörter: Cyclops, openstack
In this week’s release, the Cyclops team is proud to announce the support of the latest OpenStack release, Liberty. From the Usage Data gathering from Ceilometer to the generation of a PDF bill. Schlagwörter: bill, billing, charging, Cyclops, open source, openstack, rating
Cost and usage prediction can be a powerful tool in the hands of cloud operators as well as end users. Forecasting can help operators gain insights into the future trends in demand of compute, storage and network assets. From an end users’ perspective, forecasting enables them to perform budgeting. ICCLab’s RCB Initiative has been actively […]
In one of our projects, FICORE the continuation of FIWARE, we need to offer an Openstack-based service. One aspect of service operations is to understand the performance of the system and one particular aspect of this is to understand how long basic operations take; it is interesting to see how this evolves over time as, […]
In one of our projects, GEYSER, we were looking into a way of packaging customized code for a pilot test. Generally, we developed µservices which communicate with key Openstack components and we have specifically modified Openstack Horizon code by adding a new dashboard. These µservices as well as Openstack Horizon are quite decoupled from the […]
We had to investigate the operation of one of our Openstack compute nodes as it was exhibiting some unusual behaviour. We quickly determined that there was some unexpected packet loss and we had reason to believe that this could have been due to the packet processing in the node. Investigating this problem necessitated some deeper exploration […]
In our previous blog post we described our experience enabling floating ips through modifications to nova python libraries in an Openstack Cells deployment using nova network. That solution was not robust enough and hence we had a go at installing neutron networking, although there is very little documentation specifically addressing Neutron and Cells. Neutron’s configuration […]
In our previous blog post we presented an overview of Nova Cells describing its architecture and how a basic configuration can be set up. After some further investigation it is clear why this is still considered experimental and unstable; some basic operations are not supported as yet e.g. floating ip association as well as inconsistencies […]
