1
00:00:00,280 --> 00:00:03,500
‫So we have seen CloudFormation and Beanstalk,

2
00:00:03,500 --> 00:00:05,100
‫but now let's talk about CodeDeploys.

3
00:00:05,100 --> 00:00:06,520
‫So CodeDeploys is also a way

4
00:00:06,520 --> 00:00:10,080
‫for us to deploy our application automatically.

5
00:00:10,080 --> 00:00:13,430
‫Now the difference that CodeDeploy is a bit more permissive.

6
00:00:13,430 --> 00:00:15,710
‫It doesn't need to be using Beanstalk or CloudFormation.

7
00:00:15,710 --> 00:00:17,490
‫This is completely independent.

8
00:00:17,490 --> 00:00:18,620
‫So with CodeDeploy,

9
00:00:18,620 --> 00:00:19,570
‫We have our application,

10
00:00:19,570 --> 00:00:20,520
‫it's in version one,

11
00:00:20,520 --> 00:00:22,510
‫and we want you to upgrade it into version two.

12
00:00:22,510 --> 00:00:25,860
‫So CodeDeploy will find a way for us to do this.

13
00:00:25,860 --> 00:00:27,890
‫So CodeDeploy works with two things.

14
00:00:27,890 --> 00:00:29,650
‫It works with EC2 instances.

15
00:00:29,650 --> 00:00:32,360
‫And so you can have many EC2 instances being upgraded

16
00:00:32,360 --> 00:00:34,250
‫from V1 to V2,

17
00:00:34,250 --> 00:00:36,590
‫but it also works with On-Premises Servers.

18
00:00:36,590 --> 00:00:38,490
‫So if you have Servers On-Premises,

19
00:00:38,490 --> 00:00:40,940
‫and you want to help them upgrade from version one

20
00:00:40,940 --> 00:00:42,790
‫to version two for your applications,

21
00:00:42,790 --> 00:00:45,570
‫it is possible to do it with CodeDeploy.

22
00:00:45,570 --> 00:00:47,210
‫So CodeDeploy, If you look at it,

23
00:00:47,210 --> 00:00:48,870
‫it is what's called a hybrid service

24
00:00:48,870 --> 00:00:51,560
‫because it works both for On-Premises,

25
00:00:51,560 --> 00:00:53,800
‫and for EC2 instances.

26
00:00:53,800 --> 00:00:55,920
‫So CodeDeploy really allows you to work

27
00:00:55,920 --> 00:00:57,350
‫with any kind of servers,

28
00:00:57,350 --> 00:00:59,790
‫but you must provision the servers ahead of time.

29
00:00:59,790 --> 00:01:00,850
‫Okay, It's up to you.

30
00:01:00,850 --> 00:01:02,290
‫And you must configure them

31
00:01:02,290 --> 00:01:04,200
‫to install the CodeDeploy agent

32
00:01:04,200 --> 00:01:07,790
‫that will be assisting you to do these upgrades.

33
00:01:07,790 --> 00:01:10,510
‫So CodeDeploy is quite a handy service on AWS.

34
00:01:10,510 --> 00:01:13,020
‫It really allows people to do the transition

35
00:01:13,020 --> 00:01:16,690
‫from On-Premises to AWS by using the same way

36
00:01:16,690 --> 00:01:18,210
‫to deploy the application

37
00:01:18,210 --> 00:01:20,040
‫either with your On-Premise Servers,

38
00:01:20,040 --> 00:01:21,810
‫or your EC2 instances.

39
00:01:21,810 --> 00:01:22,990
‫And it is an advanced service,

40
00:01:22,990 --> 00:01:24,770
‫so I can't really demo it for you,

41
00:01:24,770 --> 00:01:27,120
‫but what you need to remember is that it allows you to

42
00:01:27,120 --> 00:01:29,833
‫upgrade both your EC2 instances, applications,

43
00:01:29,833 --> 00:01:33,270
‫and your On-Premises Servers applications

44
00:01:33,270 --> 00:01:34,860
‫from version one to version two,

45
00:01:34,860 --> 00:01:37,570
‫automatically from a single interface.

46
00:01:37,570 --> 00:01:38,580
‫So hope that was helpful.

47
00:01:38,580 --> 00:01:40,530
‫And I will see you in the next lecture.
