Our question was: "what is the best infrastructure to run our SaaS on?". We tried most of the infrastructure software, starting from vmware, moving to Proxmox, OpenNebula, OpenStack, and Google's Ganeti. We also considered software storage and software defined networks. We mastered some of these technologies and we even contributed to the projects. But we felt we needed something different and lighter and we "blended" our own solution, mixing and matching the best of the above and keeping in consideration our needs in terms of computing, network and storage. This talk will go through our (long) journey, understanding pros and cons of each technology and describing what we used to deliver SecurePass and other services.
