No matter if you are a lonely system administrator or the CTO of the largest carrier in the World, getting to know what’s out there is a jungle. Is VMware still the lead? I’ve heard about OpenStack, how mature is that? And what this “Ganeti” I’ve never heard of? Well, here I am. Guess what, you’re not the only one asking these questions. I traveled most of Europe hearing world’s most famous enterprises, banks and telcos and also in contact with many vendors’ labs, from San Francisco to Munich. In this presentation I just wish to give a quick overview of the state-of-the-art in the IaaS and virtualization world. This is not a sales or marketing presentation: no vaporware, just pure and real experience from the field. Enjoy the slides and stay tuned on my twitter channel on @gpaterno
