Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 00:00:00,600 --> 00:00:08,280 So let's talk about regions, so Microsoft built a lot of data centers, for example, we saw before 2 00:00:08,280 --> 00:00:11,910 a photo of one of such data center East Data centers. 3 00:00:11,910 --> 00:00:20,340 Location is called Ridgen, and there are roughly 60 Asia regions, which is more than any other cloud 4 00:00:20,580 --> 00:00:28,260 which makes Azure, if you love this public cloud region is now, as we will see later, almost every 5 00:00:28,260 --> 00:00:31,870 new resource in the cloud should be allocated to a region. 6 00:00:32,070 --> 00:00:38,350 So when we build a new virtual machine, for example, we tell Asia in which region it should be built. 7 00:00:38,970 --> 00:00:45,240 Now, this map, which is constantly updated and you should take a look at the link at the bottom of 8 00:00:45,240 --> 00:00:51,630 the screen to see the updated version of it outlines the current map of regions of Asia. 9 00:00:52,050 --> 00:00:58,590 Now, as you can see, there are quite a few regions and also there are quite a few types of regions. 10 00:00:59,310 --> 00:01:01,710 Take a look at the legend at the left of the slide. 11 00:01:01,930 --> 00:01:09,930 As you can see, there are available regions in northeast regions, availability zones, announced availability 12 00:01:09,930 --> 00:01:13,360 zones and announced region with availability zones. 13 00:01:13,410 --> 00:01:17,670 Now, right now, you probably have no idea what an availability zone is. 14 00:01:17,670 --> 00:01:19,170 And we will talk about it in a minute. 15 00:01:19,770 --> 00:01:26,270 But you can see that there are quite a few regions that were announced and are not ready yet. 16 00:01:26,580 --> 00:01:31,380 For example, right at the middle of the screen, you can see Israel Central. 17 00:01:31,650 --> 00:01:37,350 This region was announced about a year ago and it should be up and running by the end of 2021. 18 00:01:37,890 --> 00:01:43,210 Now, if you count the number of regions on this map, you will find out there are roughly 60 of them. 19 00:01:44,430 --> 00:01:51,770 So, as you can see, Asia is spread across all the world and you can find actual regions on all continents. 20 00:01:53,010 --> 00:01:54,390 Now we're discussing regions. 21 00:01:54,600 --> 00:01:56,900 We should also understand what is zone. 22 00:01:57,600 --> 00:02:04,620 So some of the regions have more than one physical data center and this is great for availability in 23 00:02:04,620 --> 00:02:07,360 case one data center is true. 24 00:02:07,410 --> 00:02:10,110 This is quite true, but it may happen. 25 00:02:10,920 --> 00:02:14,970 So each physical data center is called zone. 26 00:02:15,780 --> 00:02:22,350 And so when there are more than one data center in a region, the region is said to have availability 27 00:02:22,350 --> 00:02:22,890 zones. 28 00:02:23,370 --> 00:02:29,610 As we will see later, some cloud services benefit from availability zones, and they have the capability 29 00:02:29,940 --> 00:02:34,730 of skipping from one zone to another and do it quite transparently. 30 00:02:35,790 --> 00:02:42,060 So if it will take another look at the map, then look again at the legend and see the availability 31 00:02:42,060 --> 00:02:43,220 zones available. 32 00:02:43,410 --> 00:02:48,840 So this symbol designates that this region has more than one zone. 33 00:02:49,050 --> 00:02:56,280 For example, you can see that in West you is to there are more than one zone in Canada, central also 34 00:02:56,850 --> 00:03:00,270 West Europe, Japan, East and Australia east. 35 00:03:00,810 --> 00:03:02,950 And of course, these are just examples. 36 00:03:03,240 --> 00:03:08,670 Take a closer look at the map and you will see there are lots more of regions with availability zones. 37 00:03:10,180 --> 00:03:14,130 The next concept you should be aware of is the regions. 38 00:03:14,970 --> 00:03:19,690 Now, what this means is that some regions have designated per region. 39 00:03:20,220 --> 00:03:27,600 This is done for increased availability so that when a full region, including all its zones, fails, 40 00:03:27,750 --> 00:03:30,390 then the other one can feel its place. 41 00:03:30,780 --> 00:03:37,650 This is relevant for some of the cloud services, although to be fair, not many of them know the region. 42 00:03:37,650 --> 00:03:41,000 Pills are set by Azure and cannot be changed. 43 00:03:41,220 --> 00:03:47,910 So we can't decide that for a specific service, the region will be Region X and for another service 44 00:03:48,030 --> 00:03:49,170 it would be region way. 45 00:03:49,560 --> 00:03:53,140 The pearls are set up by Azure and cannot be changed. 46 00:03:53,550 --> 00:03:58,910 So if you will again take a look at the map, we will see the regions. 47 00:03:58,910 --> 00:04:02,580 And of course, this again is only an example and there are more. 48 00:04:02,760 --> 00:04:12,360 But as you can see, central U.S. and east US to our peers, also North Europe and West Europe are pearls 49 00:04:12,390 --> 00:04:16,430 and in addition, Central India and South India uphills. 50 00:04:16,650 --> 00:04:23,010 So that means that, for example, if I have a database which have a general application and we will 51 00:04:23,010 --> 00:04:30,720 talk in length about your application later, then the replicated data will go to the region so that 52 00:04:30,720 --> 00:04:38,070 if the region is the primary region fails, then the data is available at a secondary or the region. 5994
