Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 4 Today’s Presentation Organization of multi-media communication. Internet services.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 5 A View of Corporate Networks

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 6 The Challenge Infrastructure costs = >50% of total spending; Networks insecure; Integration costs = >50% of application costs; Network downtime = >20 hrs/year; Desktop costs = Excessive; Time to innovation = Excessive.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 7 Metrics for the Future Integrated data, voice and video services: Six Sigma+ Reliability (<5 min downtime/yr); Workstation Speed (200 Billion ops/sec); Workstation Connectivity (>1 Gigabyte/sec); Systems Reconfiguration (<1 min delay); Access to petabytes of data (<0.25 sec); Customizing an Application (<1 hr implementation); Strong authentication for access.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 8 Example of Next Generation Design

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 9 The Google Infrastructure >200,000 commodity Linux servers; Storage capacity >5 petabytes; Indexed >8 billion web pages; Capital and operating costs at fraction of large scale commercial servers; Traffic growth 20-30%/month.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 10 Dimensions of a Google Cluster 359 racks 31,654 machines 63,184 CPUs 126,368 Ghz of processing power 63,184 Gb of RAM 2,527 Tb of Hard Drive space Appx. 40 million searches/day

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 11 Architecture for Reliability Replication (3x +) for redundancy; Replication for proximity and response; Fault tolerant software for cheap hardware. Policy: Reliability through software architecture, not hardware.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 12 Query Serving Infrastructure Processing a query may engage servers; Index Servers manage distributed files; Document Servers access distributed data; Response time = <0.25 seconds anywhere.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 13 Systems Engineering Principles Overwhelm problems with computational power; Impose standard file management; Manage through standard job scheduling; Apply simplified data processing discipline.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 14 Google: The Network is the System Coordinates servers in real-time; Automates distribution of workload; Assures fault tolerance; Performs systems-wide cluster scheduling; Delivers status and performance monitoring.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 15 Intelligence Built into Services Tools examine millions of documents in real time; Automated learning for logical processing –Query: “Bay Area Cooking Classes” –Matches: “San Francisco College Classes”; “The Magic of Thai Cuisine”

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 16 Rapid Additions to Robust Infrastructure

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 17 An AJAX Application

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 18 Future: Rich Internet Applications “Thin-clients” deliver Internet services. Browsers display graphic interfaces. Standard browsers, not plug-ins. Packaged applications available on Internet. Delivery of data, voice and video. Replaces phones, TV and print media.

Copyright © 2005, Paul A. Strassmann - IP4IT - 11/15/05 19 Summary Computer-centric solutions will be replaced by network-centric services. A Google-like architectures open a way for significant reductions in the costs of Internet services. We know what will happen, just do not know how to get there.
