If you plan or already use OpenStack on Red Hat and Red Hat-based platforms, then I am sure this web site[1] is definitively going to interest you.
I think specifically to the BeNeLux customers or companies I work with and who are followers of this Blog.
RDO is a community of people using and deploying OpenStack on Red Hat and Red Hat-based platforms.
If your company or you are based in BeNeLux and are interested by IT Industrialization/Automation, just let me know and I will arrange a meeting for you.
