Last month, we showed you what’s new in OpenStack Havana in a webinar that you can download here. We explained, among other things, what's new in OpenStack Block Storage Service. (See the previous part of this summary here.) This time, we’ll talk about volume migration, transferring a volume from one tenant to another, and improved driver support. Volume migration One of the …


When we think about clouds, and specifically OpenStack, we think about provisioning virtual machines. To reliably run our business, these virtual machines must interact with other services, which may not be in other data centers or other regions. The next frontier for the cloud is enabling connectivity on demand. While telcos don't normally provide computing power to their customers, providing network …


I recently gave you an intro to my talk at the Hong Kong OpenStack Summit about Neutron namespaces. One of the commenters had seen the video of my talk and requested that we post the slideshow. In this post, I will show you how to: Identify the correct namespace. Perform general troubleshooting around the identified namespace. And, I will also share my presentation …


Articles and tutorials in the "Edge of the Stack" series cover fundamental programming issues and concerns that might not come up when dealing with OpenStack directly, but are certainly relevant to the OpenStack ecosystem. For example, drivers are often written in C rather than Python, leading to concerns about memory leaks and other C-specific issues. The "Edge of the Stack" …


Here at Mirantis we do a lot of content about theoretical or deeply technical (but important) topics, such as OpenStack Networking Tutorial: Single-host FlatDHCPManager or How to Migrate an Instance with Zero Downtime: OpenStack Live Migration with KVM Hypervisor and NFS Shared Storage.  We also do a lot of content about narrow aspects of using OpenStack, such as Configuring Floating …


Mirantis broadcast a live webinar on October 29, explaining what’s new in OpenStack Havana and fielding questions from the audience. (If you’ve missed it, or if you just want to see it again, you can download it here.)  As part of that discussion, we explained what's new in OpenStack Havana as far as OpenStack Networking, and we thought we'd bring …


Recently we introduced you to one of the freshest OpenStack projects--Rally. At the OpenStack Fall Summit last week, we showed the audience how this benchmarking tool can reveal problems with your OpenStack installation. As you may recall, Rally is a community-based project that allows OpenStack developers and operators to get relevant and repeatable benchmarking data of how their cloud operates at …


The common argument I hear against OpenStack is this: There is no dominant leader setting a clear direction. Therefore, it lacks a cohesive technical vision and will fizzle out. I don’t buy it. Yes, there is value in unified leadership. But OpenStack has other more powerful forces behind it. First, it is strongly user-driven. OpenStack users don’t just make suggestions. They roll up …


The most common model of monetizing open source is the “open core” model; the model where you build value add, proprietary features around an open source project that you package into a supported enterprise version. Eucalyptus, Alfresco and Cloudera choose this model in their respective industry segments. This post by Mike Olson also argues that “open core” is the only …


Now that OpenStack Havana’s out in the wild and the dust is starting to settle, we thought we’d take a minute to see where things finally fell out in terms of how much work was actually done, and by whom. One great thing about Stackalytics is that it lets you see OpenStack activity all the way back to Diablo, so we …
