1 00:00:00,110 --> 00:00:01,990 So here is a quick summary lecture 2 00:00:01,990 --> 00:00:03,610 to describe to you all the ways 3 00:00:03,610 --> 00:00:06,660 you can transfer a large amount of data into AWS 4 00:00:06,660 --> 00:00:08,060 and which one is going to be the most 5 00:00:08,060 --> 00:00:11,040 appropriate based on the constraints you have. 6 00:00:11,040 --> 00:00:13,240 So, for example, let's say we want to transfer 7 00:00:13,240 --> 00:00:15,640 200 Terabytes of data into the cloud, 8 00:00:15,640 --> 00:00:17,150 and what we have currently is 9 00:00:17,150 --> 00:00:19,823 a 100 Megabits per second internet connection. 10 00:00:20,740 --> 00:00:22,510 Option number one would be to use the internet, 11 00:00:22,510 --> 00:00:25,210 the public internet, or establish a Site-to-Site VPN, 12 00:00:25,210 --> 00:00:27,660 which also uses the public internet. 13 00:00:27,660 --> 00:00:29,890 And the advantage of this is that it's immediate to set up, 14 00:00:29,890 --> 00:00:31,370 we can leverage our connection right away. 15 00:00:31,370 --> 00:00:33,620 And if we do a quick computation, 16 00:00:33,620 --> 00:00:35,940 what we get is that it will take 200 terabytes 17 00:00:35,940 --> 00:00:38,540 converted into gigabytes and then megabytes, 18 00:00:38,540 --> 00:00:41,710 then you have to convert this into megabits, so times 8. 19 00:00:41,710 --> 00:00:43,670 Then you divide by the speed you have, 20 00:00:43,670 --> 00:00:46,660 so 100 megabits per second, and that gives you about 21 00:00:46,660 --> 00:00:51,220 16 million seconds, which is the equivalent of 185 days. 22 00:00:51,220 --> 00:00:54,770 So almost half a year to transfer 200 terabytes of data 23 00:00:54,770 --> 00:00:56,990 over 100 megabits internet connection. 24 00:00:56,990 --> 00:00:58,440 So this can take a long time. 25 00:00:58,440 --> 00:01:01,030 Obviously, based on the size you have the data 26 00:01:01,030 --> 00:01:02,550 it could be appropriate or not. 27 00:01:02,550 --> 00:01:04,560 And in this case, I will never probably transfer 28 00:01:04,560 --> 00:01:07,430 200 terabytes over this internet connection speed. 29 00:01:07,430 --> 00:01:09,960 If I want to transfer, now, over direct connect, 30 00:01:09,960 --> 00:01:13,890 and say we have provisioned a one gigabits per second line, 31 00:01:13,890 --> 00:01:15,090 then the first thing is that it's going to be 32 00:01:15,090 --> 00:01:16,870 a long, one-time setup. 33 00:01:16,870 --> 00:01:18,990 So if I'd never had direct connect before 34 00:01:18,990 --> 00:01:20,270 it will take about a month 35 00:01:20,270 --> 00:01:22,350 to get this connection established 36 00:01:22,350 --> 00:01:24,250 and then, once I have this connection, 37 00:01:24,250 --> 00:01:27,200 it will take about, if we do the exact same computation, 38 00:01:27,200 --> 00:01:29,300 ten times faster than my first connection, 39 00:01:29,300 --> 00:01:32,120 so it's going to end up being 18.5 days. 40 00:01:32,120 --> 00:01:35,150 So a lot quicker, but still quite long. 41 00:01:35,150 --> 00:01:38,120 Now, if I use Snowball, how long do I need? 42 00:01:38,120 --> 00:01:40,470 Well, first of all, I need to order in my snowballs, 43 00:01:40,470 --> 00:01:43,070 and then I need to get about two to three snowballs, 44 00:01:43,070 --> 00:01:44,260 and I can order them in parallels, 45 00:01:44,260 --> 00:01:47,140 so they will arrive at my facility at the same time. 46 00:01:47,140 --> 00:01:49,100 And then it takes about one week, all in all, 47 00:01:49,100 --> 00:01:50,590 from the snowball to being delivered, 48 00:01:50,590 --> 00:01:52,060 to being loaded, to being packed, 49 00:01:52,060 --> 00:01:54,240 sent back to AWS, and to the end being transferred, 50 00:01:54,240 --> 00:01:56,570 it will take about one week for the end-to-end transfer. 51 00:01:56,570 --> 00:01:59,200 And, on top of it, if there was a database 52 00:01:59,200 --> 00:02:00,720 that was being transferred through Snowball, 53 00:02:00,720 --> 00:02:02,430 it could be combined with DMS to transfer 54 00:02:02,430 --> 00:02:04,300 the rest of the data, aferwards. 55 00:02:04,300 --> 00:02:06,460 So, finally, for ongoing replications, 56 00:02:06,460 --> 00:02:08,380 so this is for one-off transfers, 57 00:02:08,380 --> 00:02:10,650 for ongoing replications, we could use techniques 58 00:02:10,650 --> 00:02:13,040 such as Site-to-Site VPN, again, because we'll have 59 00:02:13,040 --> 00:02:15,380 less data to transfer on an ongoing basis. 60 00:02:15,380 --> 00:02:17,950 Or use direct connect, or use DMS, 61 00:02:17,950 --> 00:02:20,720 or use a service like we just saw, like DataSync. 62 00:02:20,720 --> 00:02:22,040 So all these things would allow us 63 00:02:22,040 --> 00:02:24,250 to transfer the data, ongoing, 64 00:02:24,250 --> 00:02:26,550 on the ongoing basis, continuously or not, 65 00:02:26,550 --> 00:02:29,540 through some more reasonable internet's lines, 66 00:02:29,540 --> 00:02:32,400 such as Site-to-Site VPN or direct connect. 67 00:02:32,400 --> 00:02:33,410 Snowball is going to be used 68 00:02:33,410 --> 00:02:36,010 more for one-off, large transfers, 69 00:02:36,010 --> 00:02:38,120 and as we can see, Snowball, in this case, 70 00:02:38,120 --> 00:02:39,900 is really, really helpful into speeding up 71 00:02:39,900 --> 00:02:41,697 our fist data transfer into AWS. 72 00:02:42,720 --> 00:02:45,040 So this lecture's just about to make you realize 73 00:02:45,040 --> 00:02:46,840 which use case is more appropriate, 74 00:02:46,840 --> 00:02:48,900 and what are the constraints of each use case. 75 00:02:48,900 --> 00:02:50,640 And then, in the exam, you will be asked 76 00:02:50,640 --> 00:02:52,730 to figure out what is the easiest, fastest, 77 00:02:52,730 --> 00:02:55,770 or most reliable way to send data into AWS, 78 00:02:55,770 --> 00:02:58,030 if it's a small data or a large data sets. 79 00:02:58,030 --> 00:02:58,930 All right, that's it. 80 00:02:58,930 --> 00:03:00,680 I will see you in the next lecture.
