  1. What’s Hot in Clouds? • Analyze (superficially) the ~140 Papers/Short papers/Workshops/Posters/Demos in CloudCom • Each paper may fall in more than one category • CoreCloud/Virtualization/Reliability 26 plus ~2 keynotes and 5 tutorials • Applications40 plus 1 (adopting clouds) panel plus ? keynotes • Scheduling /resource allocation 16 • Security/Privacy 25 plus 1 Panel plus 1 Keynote • MapReduce31 plus 3 tutorials • Other Programming models (e.g. workflow) 9 • Storage14 plus 2 tutorials • Discovery/semantics 5 • Portal/clients 7 • Interoperability/Federation 3 plus 1 panel • Green IT 6

  2. Tutorials -- MapReduce • Yahoo on Hadoop – 40,000 nodes running Hadoop • Indiana on Twister – Iterative • Chicago on Sphere – General user processing in Map and Reduce; put communication at end of “map” and not beginning of “reduce” as in Hadoop

  3. Tutorials -- Storage • Yahoo on HDFS • Chicago on Sector – Does not spread blocks of files around, so faster than Hadoop • Bret Piatt on OpenStack – has open source service based object store like Amazon S3 (not released yet); supports CDMI Cloud Data Management Interface standard http://cdmi.sniacloud.com/ from SNIA (Industry Storage association)

  4. Tutorials -- Core Cloud Platforms • Microsoft on Azure • Spanish group on OpenNebula • RackSpace on OpenStack which has a compute (~EC2) component from NASA that is released; supports OCCI standard from OGF • Indiana on FutureGrid including Eucalyptus. FutureGrid also supports Nimbus and expects to support OpenStack and OpenNebula • Chicago on Nimbus

  5. Adopting Clouds Panel • Agreement that clouds are good for some applications – especially data-intensive and bioinformatics • Complaints about details of Hadoop – language and need for text input • Software as a Service important; • Globus has data transfer as a Service (Foster keynote) • Fortes emphasized need for SLA’s (Service Level Agreements) and multi-cloud systems (Called Sky Computing) • Gannon emphasized following day cloud – client interaction e.g. cloud backend to Excel
