Cyclops, ICCLab’s Rating-Charging-Billing solution for Cloud providers, capable of collecting usage records from both OpenStack and CloudStack, has been working with time series data from the very beginning. Our choice for database technology that is highly optimised to handle such data was InfluxDB written in GO. Time series data is generally a sequence of data […]
Previously we described how to set up post-copy live migration in OpenStack Icehouse (and it should not be a problem to set it up in the same way in Juno). Naturally, we were curious to see how it performs. In this blog post we focus on performance analysis of post-copy live migration in Openstack Icehouse […]
ICCLab had the privilege to talk about our latest research activities in “Rating, Charging & Billing” & “Performance analysis of live migrations in OpenStack” at the #vBrownBag Tech talks which were held as part of OpenStack summit in Paris. Here we provide a short summary of each talk and include the captured video for your viewing […]
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 […]
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 […]
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 […]
As system administrators it is difficult to gather performance data before going productive. Benchmarking tools offer a comfortable way to gather performance data by simulating usage of a productive system. In the OpenStack world we can employ the Mirantis Rally tool to benchmark VM performance of our cloud environment. Rally comes with some predefined benchmarking […]
