Openstack has been growing in popularity over the past few years and recently we’ve started to look into it further here at the OSL. We plan to continue to use Ganeti for our high-available IaaS needs, however we’re researching ways to integrate Openstack at the lab as well. While Ganeti provides a solid, stable and simple platform for general IaaS needs, Openstack provides better support for elastic and dynamic needs. We feel that using both platforms gives the best of both worlds, because they each fill a specific niche in a cloud environment.
Earlier this year we teamed up with IBM to work on deploying Openstack on the OpenPOWER architecture with the goal of expanding our Supercell infrastructure beyond the x86 architecture. Thanks to the hard work by both the IBM and OSUOSL team, we’ve been able to deploy Openstack on four IBM OpenPOWER machines which support KVM and little endian.
