00:00:00,270 --> 00:00:01,890
‫Okay, so let's summarize everything

2
00:00:01,890 --> 00:00:03,450
‫we've learned in this section.

3
00:00:03,450 --> 00:00:07,140
‫So SQS is a queuing service in AWS

4
00:00:07,140 --> 00:00:09,840
‫and we can have multiple producers into an SQS queue.

5
00:00:09,840 --> 00:00:11,430
‫The messages are going to be kept

6
00:00:11,430 --> 00:00:14,190
‫up to 14 days in the queue, then deleted.

7
00:00:14,190 --> 00:00:16,230
‫Consumers can read these messages

8
00:00:16,230 --> 00:00:17,160
‫and they will share the reads.

9
00:00:17,160 --> 00:00:18,870
‫So they will split the reads

10
00:00:18,870 --> 00:00:21,420
‫and then once a message is read and processed

11
00:00:21,420 --> 00:00:22,770
‫then it's going to be deleted.

12
00:00:22,770 --> 00:00:25,320
‫So when a consumer is done, the message is gone.

13
00:00:25,320 --> 00:00:28,530
‫It's used to decouple applications within AWS.

14
00:00:28,530 --> 00:00:32,280
‫So anytime you see queuing and decoupling, think SQS.

15
00:00:32,280 --> 00:00:35,730
‫SNS is a notification service in AWS.

16
00:00:35,730 --> 00:00:38,310
‫And so we have producers and subscribers.

17
00:00:38,310 --> 00:00:43,310
‫So it could be email, Lambda, SQS queues, HTTP, mobile

18
00:00:43,470 --> 00:00:46,860
‫and if you have multiple subscribers onto one SNS topic

19
00:00:46,860 --> 00:00:50,580
‫then SNS will send a message to all of them.

20
00:00:50,580 --> 00:00:52,470
‫SNS doesn't retain any message

21
00:00:52,470 --> 00:00:54,900
‫so it's not a durable store of messages

22
00:00:54,900 --> 00:00:57,150
‫and it's going to be used again for pub/sub,

23
00:00:57,150 --> 00:01:02,150
‫for subscribers, for topics and notifications within AWS.

24
00:01:02,250 --> 00:01:04,170
‫Finally, we've seen Kinesis

25
00:01:04,170 --> 00:01:07,140
‫which is a real time data streaming service

26
00:01:07,140 --> 00:01:08,850
‫which is going to have some data persistence

27
00:01:08,850 --> 00:01:10,230
‫and also you can run analytics

28
00:01:10,230 --> 00:01:12,600
‫on top of Kinesis in real time.

29
00:01:12,600 --> 00:01:14,340
‫And finally, we have Amazon MQ

30
00:01:14,340 --> 00:01:16,050
‫which is a managed message broker

31
00:01:16,050 --> 00:01:19,410
‫for Active MQ and RabbitMQ in the cloud.

32
00:01:19,410 --> 00:01:21,540
‫So if you want to migrate from on-premises

33
00:01:21,540 --> 00:01:24,510
‫to the cloud and use the MQTT, AMQP,

34
00:01:24,510 --> 00:01:27,930
‫or other kind of protocols, this is a service for you.

35
00:01:27,930 --> 00:01:28,860
‫So that's it for this section.

36
00:01:28,860 --> 00:01:31,810
‫I hope you liked it and I will see you in the next section.
