    Building a Public AMI with Ceph and OpenStack

    In an effort to show people how OpenStack and Ceph work together I decided it would be fun to build an Amazon Machine Image (AMI) for their Elastic Compute Cloud (EC2).

    We found a few critical problems with v0.56, and fixed a few outstanding problems.  v0.56.1 is ready, and we’re pretty pleased with it!

    v0.56 released

    We’re bringing in the new year with a new release, v0.56, which will form the basis of the next stable series “bobtail.”  There is little in the way of new functionality since v0.55, as we’ve been focusing primarily on stability, performance, and upgradability from the previous argonaut stable series (v0.48.x).  If you are a current […]

    What’s New in the Land of OSD?

    It’s been a few months since the last named release, Argonaut, and we’ve been busy! Well, in retrospect, most of the time was spent on finding a cephalopod name that starts with “b”, but once we got that done, we still had a few weeks left to devote to technical improvements. In particular, the OSD […]

    RBD support in CloudStack 4.0

    For the past few months I have been working towards a way to use Ceph for virtual machine images in Apache CloudStack. This integration is important to end users because it allows them to use Ceph’s distributed block device (RBD) to speed up provisioning of virtual machines. We (my company) have been long-time contributors to […]
