This is a data grid system that was built by - -3 -00:00:06,290 --> 00:00:09,720 -a biologist. And it's a system for storing and accessing big - -4 -00:00:09,720 --> 00:00:11,910 -data. So what I'm going to do, I'm going to do the same thing - -5 -00:00:11,910 --> 00:00:14,010 -that I did for the Linux system. I'm going to show you - -6 -00:00:14,010 --> 00:00:18,080 -here, on the left hand side, this clean prescriptive architecture for the - -7 -00:00:18,080 --> 00:00:21,000 -iRODS system. And I'm going to show you here on the right the - -8 -00:00:21,000 --> 00:00:22,660 -actual architecture of the system. The - -9 -00:00:22,660 --> 00:00:25,780 -descriptive architecture of iRODS. So here, - -10 -00:00:25,780 --> 00:00:27,640 -even if we don't go in and look at the details, you - -11 -00:00:27,640 --> 00:00:31,800 -can see very easily that the system is badly drifted and eroded - -12 -00:00:31,800 --> 00:00:34,500 -with respect to the way it was supposed to be. Continuing - -13 -00:00:34,500 --> 00:00:36,500 -with the examples. What I want to show you now is the - -14 -00:00:36,500 --> 00:00:39,980 -view of the complete architecture of HADOOP. As many of you probably - -15 -00:00:39,980 --> 00:00:44,210 -already know, HADOOP is an open source software framework for storage and - -16 -00:00:44,210 --> 00:00:47,990 -large scale processing of data sets. It's very broadly used. And here - -17 -00:00:47,990 --> 00:00:50,820 -is a picture of the architecture, and I hope you can see it - -18 -00:00:50,820 --> 00:00:54,290 -because the architecture is so complex and so broad and so - -19 -00:00:54,290 --> 00:00:57,050 -intertwined, and in order to be able to represent it here - -20 -00:00:57,050 --> 00:00:59,690 -in one page, I had to zoom out quite a bit. - -21 -00:00:59,690 --> 00:01:02,120 -But also in this case, you don't really have to look - -22 -00:01:02,120 --> 00:01:05,640 -at details. The important point here is that in this software architecture - -23 -00:01:05,640 --> 00:01:09,540 -61 out of the 67 components in the system have circular - -24 -00:01:09,540 --> 00:01:12,570 -dependencies. Which means that they depend on each other in a - -25 -00:01:12,570 --> 00:01:15,820 -circular way and this is normally not a good thing and also - -26 -00:01:15,820 --> 00:01:18,790 -in this case a few developers when shown the diagram had no - -27 -00:01:18,790 --> 00:01:22,120 -idea that the structure of the system was so complex and messy. |
