00:00:00,420 --> 00:00:02,730
‫Okay, so a quick lecture in introduction

2
00:00:02,730 --> 00:00:06,100
‫to the Serverless Application Repository or SAR,

3
00:00:06,100 --> 00:00:08,840
‫which is a managed repository for serverless applications

4
00:00:08,840 --> 00:00:11,280
‫that are created and packaged using SAM,

5
00:00:11,280 --> 00:00:13,420
‫so the Serverless Application Model.

6
00:00:13,420 --> 00:00:15,820
‫It's used to build and publish applications

7
00:00:15,820 --> 00:00:17,680
‫that can be reused by organizations.

8
00:00:17,680 --> 00:00:20,630
‫The idea is that you would build an application using SAM

9
00:00:20,630 --> 00:00:22,440
‫and then it can be shared publicly

10
00:00:22,440 --> 00:00:24,800
‫or it can be shared with specific AWS accounts

11
00:00:24,800 --> 00:00:25,940
‫and be reused.

12
00:00:25,940 --> 00:00:29,700
‫So we have the SAR, the Serverless Application Repository.

13
00:00:29,700 --> 00:00:32,200
‫It could be backed by an Amazon S3 Bucket.

14
00:00:32,200 --> 00:00:35,410
‫And so using SAM we're going to publish Lambda functions

15
00:00:35,410 --> 00:00:37,020
‫into this repository.

16
00:00:37,020 --> 00:00:38,520
‫And so we can publish lots of those

17
00:00:38,520 --> 00:00:41,050
‫based on if we have many different SAM applications.

18
00:00:41,050 --> 00:00:43,590
‫And then to deploy any Lambda function,

19
00:00:43,590 --> 00:00:45,030
‫instead of using SAM directly,

20
00:00:45,030 --> 00:00:47,280
‫we can source the application directly

21
00:00:47,280 --> 00:00:49,420
‫from the Serverless Application Repository

22
00:00:49,420 --> 00:00:52,070
‫to deploy them into specified accounts.

23
00:00:52,070 --> 00:00:54,690
‫So it's really a way for you to author lambda functions,

24
00:00:54,690 --> 00:00:57,140
‫to version them and have them being published

25
00:00:57,140 --> 00:01:00,120
‫in different accounts from a central repository.

26
00:01:00,120 --> 00:01:00,980
‫So why did we do this?

27
00:01:00,980 --> 00:01:02,700
‫Well, this prevents duplicate work

28
00:01:02,700 --> 00:01:04,760
‫and we just go straight to the publishing phase.

29
00:01:04,760 --> 00:01:07,280
‫And we can customize the application

30
00:01:07,280 --> 00:01:09,130
‫from SAR into the deployments

31
00:01:09,130 --> 00:01:12,010
‫using settings and environment variables

32
00:01:12,010 --> 00:01:14,620
‫as I will be showing you in the future hands-on.

33
00:01:14,620 --> 00:01:16,330
‫So that's it just for the short introduction,

34
00:01:16,330 --> 00:01:18,080
‫you will make a lot of sense once we start using it.

35
00:01:18,080 --> 00:01:20,730
‫So I will see you in the next lecture for a hands-on.
