TryStack an OpenStack test bed
TryStack [announced Feb 16th], is a test bed of OpenStack's "latest and gratest" - well not quite the latest and graetest but it will get there..., you can watch the presntation by Jay Pipes on TryStack's architecture and services here .
This is a great opertunity of understanding what OpenStack can give you without starting setting it up yourself, atough there are a few howto's around on how to go about and do so to.
In order to try TryStack go to https://trystack.org/ and join the TryStack group on Facebook and get your account, there are currently 1,204 members which is pretty impressive. TryStack's available resources are: 156 cores, 1040GB memory and 59.1 which is also quite impressive for a free, community intiative.
Please note: any instance you may setup will only be available for 24 hours - so don't try going production on this ...
