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 […]
In this tutorial, we will be speaking about a “Swiftbox”. This is nothing more than our terminology for an Openstack installation that only needs and uses Swift and Keystone. The use and setup of this Swiftbox will be explained in this article. The reason why someone might want a stripped-down OpenStack installation with only Swift […]
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 […]
The SOUL-FI FIWARE Accelerator is one of 16 incubators that joined the FI-PPP with the beginning of the 3rd and most important phase of the Future Internet innovation program.
The mission of these 16 accelerators is to accelerate the uptake of the FIWARE technology foundation, which has been built in the previous two phases and has now reached a level of maturity that qualifies it for competing in the innovation wild. Consequently, the correct name of these 16 incubators is FIWARE Accelerators.
Since our servers have been set up for live migration with Openstack Icehouse, we wondered how live migration would perform. We measured the duration of the migration process, VM downtime duration and the amount of data transfered via the ethernet during a live migration. All tests were performed across 5 different VM flavors to examine the impact […]
We are conducting research in order to find out which features of the XIFI platform are most important to end users. The results will be used in order to improve the platform. If you are an application developer interested in XIFI, please feel free to participate in the survey which can be found following this […]
In this article I will show how to install a Windows 7 64-Bit image on OpenStack. For different versions of Windows watch out for the corresponding notes in the article. Prepare the Installation Ubuntu, QEMU and KVM Creating a Windows image from scratch is best done by using a linux distribution to do the installation […]
Description The widespread adoption and the development of cloud platforms have increased confidence in migrating key business applications to the cloud. New approaches to distributed computing and data analysis have also emerged in conjunction with the growth of cloud computing. Among them, MapReduce and its implementations are probably the most popular and commonly used for […]
