1
00:00:00,360 --> 00:00:03,350
‫So let's summarize what we have learned in this section.

2
00:00:03,350 --> 00:00:05,270
‫The first one around the EBS volumes,

3
00:00:05,270 --> 00:00:06,970
‫they are network drives that are attached

4
00:00:06,970 --> 00:00:08,930
‫to one EC2 instance at a time.

5
00:00:08,930 --> 00:00:11,810
‫They're mapped to a specific Availability Zone

6
00:00:11,810 --> 00:00:15,060
‫and we can use the EBS snapshot feature to do backups

7
00:00:15,060 --> 00:00:18,400
‫or to be able to transfer the data from one EBS volume

8
00:00:18,400 --> 00:00:22,260
‫across to an other Availability Zone.

9
00:00:22,260 --> 00:00:23,093
‫We've seen about AMIs.

10
00:00:23,093 --> 00:00:26,410
‫There are ready to use EC2 instances images, with

11
00:00:26,410 --> 00:00:27,700
‫the customizations we want.

12
00:00:27,700 --> 00:00:30,930
‫And if we want to automate the process of building an AMI

13
00:00:30,930 --> 00:00:33,390
‫we can use the EC2 image builder service to

14
00:00:33,390 --> 00:00:36,850
‫automatically build tests and distribute AMIs.

15
00:00:36,850 --> 00:00:38,850
‫We've seen EC2 instance store, which is a way

16
00:00:38,850 --> 00:00:41,680
‫for us to have a very high performance hardware disc

17
00:00:41,680 --> 00:00:44,350
‫this time, attached to our EC2 instance.

18
00:00:44,350 --> 00:00:45,300
‫But it is lost

19
00:00:45,300 --> 00:00:48,260
‫in case our instances stopped or terminated.

20
00:00:48,260 --> 00:00:49,870
‫If we wanted to have a network file system,

21
00:00:49,870 --> 00:00:51,820
‫we would use the EFS service.

22
00:00:51,820 --> 00:00:52,830
‫With EFS service,

23
00:00:52,830 --> 00:00:55,290
‫we can get a NFS that we can attach

24
00:00:55,290 --> 00:00:57,700
‫to hundreds of instances within the region.

25
00:00:57,700 --> 00:00:59,100
‫So there is no AZ luck,

26
00:00:59,100 --> 00:01:00,850
‫now it's at the region level.

27
00:01:00,850 --> 00:01:03,231
‫And if you want to cost-optimize our EFS service,

28
00:01:03,231 --> 00:01:05,222
‫we could use EFS-IA,

29
00:01:05,222 --> 00:01:08,154
‫which allows us to move the files that are infrequently used

30
00:01:08,154 --> 00:01:11,890
‫into a lower cost tier.

31
00:01:11,890 --> 00:01:14,770
‫Finally, we've seen about FSx, FSx for Windows,

32
00:01:14,770 --> 00:01:17,900
‫which is a way for us to get a network file system

33
00:01:17,900 --> 00:01:19,310
‫for Windows servers

34
00:01:19,310 --> 00:01:21,400
‫and FSx for Luster, which is

35
00:01:21,400 --> 00:01:23,530
‫for us to perform high performance computing.

36
00:01:23,530 --> 00:01:27,420
‫So HPC on a Linux file system.

37
00:01:27,420 --> 00:01:29,650
‫So to say for this section, I hope you liked it

38
00:01:29,650 --> 00:01:31,850
‫and that I will see you in the next section.
