DSI: A New Architecture for Secure Carrier-Class Linux Clusters
We presented the need for a new security approach for telecom applications running on carrier class Linux clusters. Based on our motivations to develop a coherent solution addressing the security needs of Linux carrier class clusters, we proposed a new design for a secure distributed infrastructure. We presented the main elements of this design and discussed some of the preliminary results. We believe that this design is a practical approach to enhance security for large-scale clusters with carrier-class needs.
To complete DSI, we plan to collaborate with open source initiatives and other organizations. The DSI team from Ericsson Research will be available at the Ottawa Linux Symposium for three allocated presentations on DSI. We will also be available at the IEEE Cluster Conference 2002 in Chicago. In addition, Ericsson Research will be hosting the annual Open Cluster Group meetings June 24-25 in Montreal, which will give us the opportunity to address the members of the group and get them involved with the DSI project.
We are currently preparing a web site that will be available in late June. It will provide DSI technical reports, presentations, source code and links to web sites of other contributors. We encourage people interested in DSI to contact any of the DSI team members (listed below) to receive detailed papers on the DSI architecture, strategy, source code and to discuss collaboration opportunities.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
