This is actually really great. One of the things I hated so far about Rackspace Cloud was that I couldn't scale the resources independently. If I need to upgrade to multiple CPU's or more RAM I don't want to be required to double or triple my disk capacity - that's a giant waste, especially with the availability of Cloud Files.<p>Now if their Database hosting would include Mongo, I'm sold!
I'm glad and grateful they've open sourced their stack.<p>Yet it sheds some amusing light on their pricing;<p><pre><code> Openstack at Rackspace: 30G Ram, 1.2T Disk = $1314/mo
</code></pre>
Rent a box at Hetzner, take the time to install Openstack;<p><pre><code> Openstack at Hetzner: 32G Ram, 2x3T Disks, probably faster CPU = $77/mo
</code></pre>
Obviously that only makes sense when your time is "free", and Hetzner is not exactly as solid as Rackspace. And you should rent a couple more boxes for redundancy.<p>But still, I'm almost tempted to start a little Hetzner-Cloud...
It's good to see the option of SSD-backed block storage in a major cloud provider like Rackspace. Block IO is a killer for a lot of apps. Though, we'll have to see if the benchmarks support their claims though.
Couple of additional comments about the OpenStack projects all of the new services are powered by on this HN submission: <a href="http://news.ycombinator.com/item?id=3847486" rel="nofollow">http://news.ycombinator.com/item?id=3847486</a>
Here's to hoping that its cloudfiles implementation no longer uses a file replicated sqlite db for indexing. (iirc it did earlier on. Scared me stupid when I found out).
