  1. Distributed Computing Systems Current Issues in DCS Dr. Sunny Jeong. spjeong@uic.edu.hk Mr. Colin Zhang colinzhang@uic.edu.hk With Thanks to Prof. G. Coulouris, Prof. A.S. Tanenbaum and Prof. S.C Joo

  2. Cluster, Grid, Cloud …Now…Hadoop? • To Support hadling Big data • Hadoop HDFS + MapReduce • designed so that any node failures are automatically handled by the framework. • enables applications to work with thousands of computation-independent computers and petabytes of data. • Facebook Yahoo..of course GOOGLE

  3. Overview • Hadoop • Computer Cluster • Grid Computing • Grid Computing Projects 3

  4. Hadoop Architecture • Wikipedia

  5. MapReduce Architecture • Yuan Luo

  6. HDFS Architecture • Dhruba Borthakur

  7. Clustering Computing • Consists of a set of loosely connected computers that work together as a single system. • The components of a cluster are usually connected to each other through fast LAN, each node with own OS • Availability of low cost microprocessors, high speed networks, and software for high performance distributed computing 7

  8. Grid Computing • Computational Grid: • Focus on CPU scavenging/stealing technology for complicated operation • Data Grid): Managing and sharing distributed intensive data • Access Grid: For Cooperation between remote computer using audio or video applications • Equipment Grid : Controlling remote machine and analyzing data from the machine.

  9. Grid Project • SETI@home • BOINC • holding@home • korea@home(stopped in 2011)

  10. Cloud Computing( comparison with Grid) • Service Oriented • Transaction oriented • No standardization Organization • No Standard Technology • More less homogeneous gathering (compare to Grid) • Loosely connected 10

  11. Barriers of the Concepts • Shimyoung cheol
