On 22nd April 2016 the 11th Experts Talk on Next Generation Service Delivery Platforms (NGSDP) was held at the Telekom Innovation Laboratories in Berlin. The purpose of the event is to bring together thought-leaders in the area of Next Generation Services to discuss the state of the art in the field. Schlagwörter: 5G, ACeN, CloudStack, […]
[Note: this project took place as part of the ICCLab Hackathon – more general information on the ICCLab Hackathon is here]. Shared inventories, such as office fridges that contains items having an expiration date, have always been a problem to manage. Our very own fridge isn’t an exception either. At the moment, about 35 of us (ICCLab […]
Project Clearwater is an open source implementation of IP Multimedia Subsystem (IMS) developed for scalable deployment in the cloud to provide voice, video and messaging services. There has been work done before on orchestrating Clearwater in OpenStack using Cloudify. We, in cooperation with our partner – Citrix, present orchestration of this system in Apache CloudStack […]
This blog post presents a plugin for OpenStack Heat which adds support for Apache CloudStack resources and thus enables a template-based orchestration on CloudStack using Heat. As this plugin extends the standard Heat’s resource type list it can also be used within our Hurtle orchestrator for providing your application as a service or any other […]
Service scheduling and task placement within large-scale clusters is receiving a lot of interest in the cloud community at present. Moreover, service scheduling is one of the keystones of our recently kicked off ACeN project and we finally got a chance to experiment with the technology that is currently a frontrunner in this area – […]
Up to now, we have published several blog posts focusing on the live migration performance in our experimental Openstack deployment – performance analysis of post-copy live migration in Openstack and an analysis of the performance of live migration in Openstack. While we analyzed the live migration behaviour using different live migration algorithms (read our previous blog posts regarding pre-copy […]
In our previous blog posts we mostly focused on virtual machine live migration performance comparing pre-copy, post-copy and hybrid approaches in an Openstack context rather than exploring other live migration features. Libvirt together with the Qemu hypervisor provides many migration configuration options. One of these options is a possibility to use tunneled live migration. Recently […]
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 […]
We have shed blood, sweat and tears trying to get post-copy live migration working in OpenStack over the last month: this blogpost explains all the necessary steps to make it work and hopefully it will save future post-copy pioneers some pain. In our previous blog post we focused on setting it up in QEMU. This […]
Hurray! We have finally deployed QEMU 2.1.5 with post-copy live migration support on our servers! But before we get to that, a little bit of context… in our previous blog posts we focused on performance analysis of pre-copy live migration in Openstack. So far all of our experiments were done using QEMU version 1.2 with […]
