An HPC way of usage for.openstack at.mercadolibre is for example to run integration and regresions test on productios pre and post deploy too. So Jenkins servers are shooted in a minute to support the tests load and then they destroy themselves. On Dec 2, 2011 3:55 PM, "Oliver Baltzer" <oli...@hytek.org> wrote:
