1
00:00:00,130 --> 00:00:00,963
‫So this is something

2
00:00:00,963 --> 00:00:02,550
‫that may look obvious for you

3
00:00:02,550 --> 00:00:03,505
‫but what is the difference

4
00:00:03,505 --> 00:00:05,040
‫between CloudTrail, CloudWatch and X-Ray?

5
00:00:05,040 --> 00:00:08,510
‫I'll just try to summarize it in one slide.

6
00:00:08,510 --> 00:00:11,240
‫So CloudTrail is to audit API calls

7
00:00:11,240 --> 00:00:12,830
‫that are made in your account

8
00:00:12,830 --> 00:00:16,120
‫by user, services or even from the AWS console.

9
00:00:16,120 --> 00:00:17,460
‫It's really useful when you want

10
00:00:17,460 --> 00:00:18,690
‫to detect unauthorized calls

11
00:00:18,690 --> 00:00:19,940
‫or you wanna find the root cause

12
00:00:19,940 --> 00:00:21,623
‫of changes due to API calls.

13
00:00:22,460 --> 00:00:26,250
‫Now, CloudWatch is to use metrics for monitoring,

14
00:00:26,250 --> 00:00:27,730
‫so CloudWatch Metrics for monitoring

15
00:00:27,730 --> 00:00:30,960
‫and CloudWatch Logs for storing the application logs.

16
00:00:30,960 --> 00:00:32,650
‫CloudWatch Alarms to send notification

17
00:00:32,650 --> 00:00:35,070
‫in case of unexpected metrics, for example.

18
00:00:35,070 --> 00:00:38,480
‫And so all of this has to do with monitoring, okay?

19
00:00:38,480 --> 00:00:39,730
‫So CloudTrail is API calls,

20
00:00:39,730 --> 00:00:41,690
‫CloudWatch is going to be around monitoring.

21
00:00:41,690 --> 00:00:44,090
‫X-Ray is for automated trace analysis

22
00:00:44,090 --> 00:00:46,120
‫and central service map visualization

23
00:00:46,120 --> 00:00:48,390
‫so if you have a distributed service,

24
00:00:48,390 --> 00:00:50,040
‫this is a great way to look at things.

25
00:00:50,040 --> 00:00:51,670
‫And this is really helpful for debugging

26
00:00:51,670 --> 00:00:53,970
‫and also looking at stuff like latency,

27
00:00:53,970 --> 00:00:55,940
‫errors and fault analysis

28
00:00:55,940 --> 00:00:58,190
‫from within the X-Ray console.

29
00:00:58,190 --> 00:00:59,520
‫You can also get, as I said,

30
00:00:59,520 --> 00:01:02,250
‫request tracking across your distributed systems.

31
00:01:02,250 --> 00:01:04,210
‫So hopefully that makes it pretty clear

32
00:01:04,210 --> 00:01:06,340
‫which service is used for what.

33
00:01:06,340 --> 00:01:08,540
‫CloudWatch is really just for overall metrics,

34
00:01:08,540 --> 00:01:10,420
‫X-Ray is a lot more granular,

35
00:01:10,420 --> 00:01:12,530
‫trace-oriented type of service

36
00:01:12,530 --> 00:01:15,290
‫and CloudTrail is going to be for auditing API calls.

37
00:01:15,290 --> 00:01:16,610
‫Okay, hope that was helpful.

38
00:01:16,610 --> 00:01:18,360
‫I will see you in the next lecture.
