The "Open Stack" refers to a set of technologies that work together to make it easier for web developers and users to manage access to user data across the Web. It lets users create a consistent Digital Identity carrying information, data and connections all around different web sites. The OpenStack is designed to manage authentication (OpenID), grant access to users' data (OAuth), share contacts information (Portable Contacts), develop social applications (OpenSocial) and describe social activities (ActivityStreams). The most important players in IT market nowadays are developing solutions based on OpenStack technology (Google, Yahoo!) or they are creating their own similar technologies (Facebook). In this talk, I'll describe the state of art of OpenStack technologies in the current "social" web and how you can use it in practice in deploying your own web system.
