OpenStack is a free, open-source project that allows anyone to create their own cloud infrastructure. Used by the likes of NASA, CERN, AT&T and Sony, we will be looking at the reasons for its success and how it is emerging as a powerful competitor to Google and AWS. In our deep-dive, we will look at what OpenStack really is and what services it can offer to both developers and business owners. We will also get our hands dirty by writing some code, and seeing how easy it is to spin up servers, CDNs and databases in a matter of minutes.
