00:00:00,240 --> 00:00:06,870
In this section, we are going to do hands on lab, which is the Amazon since notifications subscribe

2
00:00:06,870 --> 00:00:14,220
from the ADA is Lambda, so we can use a lambda function to subscribe to an Amazon sans topic.

3
00:00:14,220 --> 00:00:17,070
Here you can see the architecture on the slide.

4
00:00:17,100 --> 00:00:24,120
Basically we will publish message with using the our client operations to the Amazon Sans and Amazon

5
00:00:24,120 --> 00:00:30,780
Sans will be published message to the notification topic and this will be subscribe from the is lambda

6
00:00:30,780 --> 00:00:37,950
and this will trigger the lambda function and consume the notification topic from the lambda function.

7
00:00:37,950 --> 00:00:42,090
So we will follow the steps during the Hands-On Lab.

8
00:00:42,120 --> 00:00:45,480
Basically, we will create an Amazon sans topic.

9
00:00:45,480 --> 00:00:47,700
After that we will create a Lambda function.

10
00:00:47,700 --> 00:00:54,150
We will create a lambda subscription to Amazon sans topic and develop lambda actual function code for

11
00:00:54,150 --> 00:00:56,580
incoming event from the Amazon sans topic.

12
00:00:56,580 --> 00:01:01,560
And we will publish message to the Amazon Sans and see end to end architecture.

13
00:01:01,560 --> 00:01:03,720
We are testing publishing the message.

14
00:01:04,170 --> 00:01:09,030
So as you know that when we implement any architecture on a we have two main steps.

15
00:01:09,060 --> 00:01:15,360
The first step is create infrastructure on a cloud and the second step is developing lambda actual code

16
00:01:15,360 --> 00:01:17,130
for interacting to SNS.

17
00:01:17,220 --> 00:01:19,920
So we will start with the first step.

18
00:01:19,920 --> 00:01:24,420
So that means let's create this architecture infrastructure on the cloud.
