John Engates, CTO, Rackspace Hosting

Title: The Shift to Cloud – Where are we now and where are we headed?

We will cover the shift from traditional IT infrastructure to the cloud, progress so far, and a preview of where we’re headed. We will highlight some of the technologies powering the cloud and being delivered on top of the cloud. We will also discuss the areas of computing that work well in the cloud today and what needs to be done before we can truly realize the full power of the cloud.


John Engates joined Rackspace in August 2000, just a year after the company was founded, as Vice President of Operations, managing the datacenter operations and customer-service teams. Two years later, when Rackspace decided to add new services for larger enterprise customers, John created and helped develop the Intensive Hosting business unit.

Most recently, John has played an active role in the evolution and evangelism of Rackspace’s cloud-computing strategy and cloud products. John meets frequently with customers to hear about their needs and concerns, and to discuss Rackspace’s vision for the future of cloud computing. John currently serves as Chief Technology Officer.

John is also an internationally recognized cloud computing expert and a sought-after speaker at technology conferences, including CA World, the Goldman Sachs Techtonics Conference and Cloud Expo. He speaks on the future of cloud computing, enterprise cloud adoption, data center efficiency, green data center best practices, and more.

Prior to joining Rackspace, John was a founder and General Manager at Internet Direct, one of the original Internet service providers in Texas.

John is a graduate of the University of Texas at San Antonio and holds a B.B.A. in Accounting.

Ttitle: Managing Interference in Cooperative Wireless Networks
We present a general description of current wireless communication technologies.
We argue the need for cooperative wireless networks and discuss the existing methodologies.
Our emphasis is on the distributed nature of the network and the need for simultaneous transmission from different users.
Then, we address the role of interference in such a distributed network and the corresponding challenges in designing reliable systems.
Finally, we discuss the design of quantized feedback in wireless relay-interference networks.
