I agree that it's an immature platform. That said, it's also a very young platform and isn't that to be expected? There's a number of things that need to be fixed before I'd ever recommend Nova's use in production: 1. There's no upgrade path currently. Upgrading requires fairly substantial downtime. 2. Live migration is broken. Utterly. 3. Every release fixes so many things that it's really important to upgrade every time; however, only one release will likely be supported every Ubuntu LTS release, meaning you're either stuck with a really old (likely broken) version of nova, or you're stuck will a very likely unstable version of Ubuntu. This will be easier over time, when nova is more stable and has less bugs, but it's incredibly painful right now. That said, I feel OpenStack's strengths greatly outweigh its immatureness. I ran a private cloud at my last organization using a VMWare ESXi cluster. It was more mature, upgrades worked appropriately, live migration was solid, etc. I had (and still have) the choice to run VMWare for my current project and am extremely happy with my choice of OpenStack. The flexibility provided by the platform and my ability to contribute to its future make its immaturity a non-concern. Every release gets closer and closer to a stability point I'm comfortable with. This article isn't bad news. In fact, I'd say it shows that competitors see OpenStack as a fairly major threat. We should be celebrating this ;). - Ryan _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
