We've implemented OpenNebula here at Brainfood and after having had some experience with it I would say that having that kind of infrastructure simplifies management rather than making it more complicated. Having a bunch of hand baked KVMs running without coordinated migration or shared storage is a lot more fragile, confusing and slow to work with. For instance, if we need to service a machine we can tell OpenNebula to "flush" that host and it will automatically balance all the virtual machines running on that machine to other hosts. That's a big convenience.
I'm sure OpenStack has similar capabilities. We evaluated it along with a number of other infrastructures and for us OpenNebula was just the easiest to get going from the stock Debian packages. We also have found it to be very hackable. A lot of its functionality actually lives in shell scripts rather than some DSL or Ruby code. ----- "Lucas Nussbaum" <[email protected]> wrote: > 3. to provide a place to experiment with new services > + create a "Debian cloud" with virtual machines to develop new > services > (maybe providing manually-created VMs would be enough -- I'm not > sure we > need a complex infra such as OpenStack). -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
