First, Jonathan Bryce welcomes the arrival of everyone. After that, he asks the audience: "how many of us submitted the code for the first time in the Icehouse version?" with many applause, many people stood up. I have to admit that in this summit, we have many new faces and new ideas. These new ideas and potentials are also playing a vital role in how to make OpenStack more flexible, unique and powerful. I think that's why OpenStack is so successful.

After that, Jonathan Bryce told the audience, "now every company is competing with start-ups, and more and more companies are using OpenStack to cut costs and promote innovation. More importantly, OpenStack is changing their business models." Here, Jonathan Bryce presents the concept of super user (superuser) to the audience, and announces that the OpenStack foundation will launch the online publication "Superuser".
