00:00:00,210 --> 00:00:05,760
In this video, we are getting started with Amazon SNES using a machine console.

2
00:00:05,970 --> 00:00:10,920
So we will create a topic on Amazon since using a measurement console.

3
00:00:11,400 --> 00:00:19,230
But before we start, please open the console and search for the Amazon RSNs and click the start button

4
00:00:19,230 --> 00:00:25,620
in order to add favorites and open the begin page of Amazon RSNs, which is a simple notification service.

5
00:00:25,950 --> 00:00:31,770
Amazon RSNs is pop up messaging service for microservices and service applications.

6
00:00:31,890 --> 00:00:39,150
So we will decouple our microservices using Amazon RSNs with the pop up messaging features in the hands

7
00:00:39,480 --> 00:00:40,710
of the Amazon RSNs.

8
00:00:40,710 --> 00:00:45,690
And you can scroll down and see the benefits and features and use case of Amazon RSNs.

9
00:00:45,720 --> 00:00:51,390
So if you go to the beginning of this page, the important part is create a topic that we will create

10
00:00:51,390 --> 00:00:52,820
a topic during this video.

11
00:00:52,830 --> 00:01:00,420
So let me start with what is a topic and Amazon RSNs topic is a logical access point to act as a communication

12
00:01:00,420 --> 00:01:00,960
channel.

13
00:01:01,140 --> 00:01:03,330
So a topic is a message channel.

14
00:01:03,330 --> 00:01:09,750
When we publish a message to the topic, it fan the message to all subscribed endpoints.

15
00:01:09,750 --> 00:01:17,100
So we will use this topic operation for example, if you think that we are developing e-commerce application

16
00:01:17,100 --> 00:01:25,440
with multiple other services and when we file an event like the checkout, checkout order or fulfillment

17
00:01:25,440 --> 00:01:29,880
to order, we can create a topic for our producers and subscribers.

18
00:01:29,880 --> 00:01:33,330
Producers will consume our topic with the final way.

19
00:01:33,930 --> 00:01:36,750
The first and most common use case is Amazon.

20
00:01:36,790 --> 00:01:40,050
SNS task is creating a topic for that purpose.

21
00:01:40,050 --> 00:01:46,200
Let's write the topic name for example, my topic in here and click the next step.

22
00:01:47,060 --> 00:01:52,040
So as you can see that it is come to create a topic page that we can configure our topic.

23
00:01:52,070 --> 00:01:58,730
The type of the topic will be standard and also you can see you can select the FIFO, but the standard

24
00:01:58,730 --> 00:02:06,230
is the best practice to use if you don't require the FIFO to get performance benefit and use Scaled

25
00:02:06,230 --> 00:02:07,250
or SAS.

26
00:02:07,250 --> 00:02:13,490
And if you scroll down you can see the name of our topic and if you scroll down you can change the display

27
00:02:13,490 --> 00:02:18,980
name and if you scroll down you can see the other configurations, which is the encryption access point,

28
00:02:18,980 --> 00:02:22,100
delivery type policy text and so on.

29
00:02:22,100 --> 00:02:26,870
So I'm, I'm leaving as it is all this conversation and click the create topic button.

30
00:02:28,420 --> 00:02:33,670
So during creation we can choose a topic type, as you remember, that is standard or five four and

31
00:02:33,670 --> 00:02:35,050
named our topic name.

32
00:02:35,080 --> 00:02:39,080
After creating a topic, we can change the topic type or the name.

33
00:02:39,100 --> 00:02:45,100
All other configuration choices are optional during the topic creation and we can edit them after that.

34
00:02:45,100 --> 00:02:51,400
So now as you can see that we have created our topic and see the details and configurations in here

35
00:02:51,430 --> 00:02:55,120
that we can use and change some of the configurations in here.
