00:00:00,560 --> 00:00:03,010
‫Okay, so let's talk about a new service
2
00:00:03,010 --> 00:00:05,950
‫that I really like and that does come up in the exam now.
3
00:00:05,950 --> 00:00:08,810
‫It is called EC2 Image Builder.
4
00:00:08,810 --> 00:00:11,080
‫It is used to automate the creation
5
00:00:11,080 --> 00:00:14,870
‫of virtual machines or container images.
6
00:00:14,870 --> 00:00:17,090
‫Concretely, what does that mean for the exam?
7
00:00:17,090 --> 00:00:18,540
‫That means that you're gonna be able
8
00:00:18,540 --> 00:00:20,190
‫with EC2 Image Builder
9
00:00:20,190 --> 00:00:23,530
‫to automate the creation, maintain, validate
10
00:00:23,530 --> 00:00:27,690
‫and test AMIs for EC2 instances.
11
00:00:27,690 --> 00:00:28,980
‫So let's have a look at a diagram
12
00:00:28,980 --> 00:00:31,100
‫to see how that works in a detail.
13
00:00:31,100 --> 00:00:33,880
‫So we have the EC2 Image Builder service,
14
00:00:33,880 --> 00:00:35,070
‫and we're going to set it up,
15
00:00:35,070 --> 00:00:36,720
‫as we'll see in the next lecture.
16
00:00:36,720 --> 00:00:39,310
‫And it is automatically, when it's going to run,
17
00:00:39,310 --> 00:00:41,730
‫it is going to create an EC2 instance
18
00:00:41,730 --> 00:00:43,610
‫called a Builder EC2 instance.
19
00:00:43,610 --> 00:00:47,630
‫And that EC2 instance is going to build components
20
00:00:47,630 --> 00:00:49,090
‫and customize a software.
21
00:00:49,090 --> 00:00:52,800
‫For example, install Java, update the CLI,
22
00:00:52,800 --> 00:00:55,690
‫update the software system, maybe install firewalls,
23
00:00:55,690 --> 00:00:58,550
‫whatever you define to happen on that EC2 instance,
24
00:00:58,550 --> 00:01:00,400
‫maybe install your application.
25
00:01:00,400 --> 00:01:02,290
‫And then once this is done,
26
00:01:02,290 --> 00:01:04,990
‫then an AMI is going to be created
27
00:01:04,990 --> 00:01:07,170
‫out of that EC2 instance.
28
00:01:07,170 --> 00:01:09,613
‫But all of this is obviously automated.
29
00:01:10,470 --> 00:01:12,800
‫Then the AMI is created, but we want to validate it.
30
00:01:12,800 --> 00:01:16,980
‫So EC2 Image Builder will automatically create
31
00:01:16,980 --> 00:01:20,530
‫a test EC2 instance from that AMI
32
00:01:20,530 --> 00:01:22,690
‫and going to run a bunch of tests
33
00:01:22,690 --> 00:01:24,830
‫that you are defining in advance.
34
00:01:24,830 --> 00:01:25,890
‫And if you don't wanna run any tests,
35
00:01:25,890 --> 00:01:28,270
‫obviously, you can just skip that test.
36
00:01:28,270 --> 00:01:30,670
‫But the test can be asking,
37
00:01:30,670 --> 00:01:31,870
‫is the AMI working?
38
00:01:31,870 --> 00:01:32,970
‫Is it secure?
39
00:01:32,970 --> 00:01:34,920
‫Is my application running correctly?
40
00:01:34,920 --> 00:01:36,310
‫All these kind of things.
41
00:01:36,310 --> 00:01:39,490
‫And then once the AMI is tested,
42
00:01:39,490 --> 00:01:42,050
‫then the AMI is going to be distributed.
43
00:01:42,050 --> 00:01:45,390
‫So while EC2 Image Builder is original service,
44
00:01:45,390 --> 00:01:48,180
‫it is possible for you to take that AMI
45
00:01:48,180 --> 00:01:50,980
‫and distribute it to multiple regions,
46
00:01:50,980 --> 00:01:52,420
‫therefore allowing your application
47
00:01:52,420 --> 00:01:54,713
‫and your workflow to be truly global.
48
00:01:56,090 --> 00:01:59,800
‫Next, EC2 Image Builder can be run on a schedule,
49
00:01:59,800 --> 00:02:01,750
‫so you can define a weekly schedule,
50
00:02:01,750 --> 00:02:04,770
‫or you can run whenever packages are updated,
51
00:02:04,770 --> 00:02:07,410
‫or you can run them manually, et cetera, et cetera.
52
00:02:07,410 --> 00:02:09,000
‫And it is a free service,
53
00:02:09,000 --> 00:02:12,450
‫so you're only going to pay for the underlying resources.
54
00:02:12,450 --> 00:02:13,400
‫What does that mean?
55
00:02:13,400 --> 00:02:17,000
‫Well, that means that if you create an EC2 instance
56
00:02:17,000 --> 00:02:18,670
‫during this process,
57
00:02:18,670 --> 00:02:22,290
‫and EC2 Image Builder will create these EC2 instances,
58
00:02:22,290 --> 00:02:24,830
‫then you're going to pay for these EC2 instances.
59
00:02:24,830 --> 00:02:27,400
‫And when the AMI is created and distributed,
60
00:02:27,400 --> 00:02:28,940
‫you're going to pay for the storage
61
00:02:28,940 --> 00:02:32,010
‫of that AMI wherever it has been created
62
00:02:32,010 --> 00:02:34,040
‫and wherever it has been distributed,
63
00:02:34,040 --> 00:02:35,470
‫but that should make sense, right?
64
00:02:35,470 --> 00:02:37,210
‫So in the next lecture, we'll have a look
65
00:02:37,210 --> 00:02:41,010
‫at how this service works to really have a concrete idea
66
00:02:41,010 --> 00:02:44,860
‫of the automation provided by EC2 Image Builder.
67
00:02:44,860 --> 00:02:46,760
‫So I will see you in the next lecture.
