1
00:00:01,250 --> 00:00:03,130
Welcome back. In this lesson,

2
00:00:03,130 --> 00:00:07,120
we are going to talk about "Optimizing Resource Management".

3
00:00:07,120 --> 00:00:09,084
And I'm just going to be upfront with you right

4
00:00:09,084 --> 00:00:11,838
at the start, this is going to be kind of a weird lesson,

5
00:00:11,838 --> 00:00:15,200
at least as far as the DP-203 is concerned.

6
00:00:15,200 --> 00:00:18,811
See, there's a few topics in the exam requirements

7
00:00:18,811 --> 00:00:22,650
that don't really tie to much of anything.

8
00:00:22,650 --> 00:00:24,300
They're very vague.

9
00:00:24,300 --> 00:00:26,440
So some are extremely clear,

10
00:00:26,440 --> 00:00:29,421
like we need to figure out how to set up distribution.

11
00:00:29,421 --> 00:00:31,260
Okay, well, I can teach you that.

12
00:00:31,260 --> 00:00:32,480
But some of the things like this

13
00:00:32,480 --> 00:00:35,060
are rather obscure or vague.

14
00:00:35,060 --> 00:00:37,690
And so for the DP-203, there's not going to be

15
00:00:37,690 --> 00:00:40,000
a ton of practical application,

16
00:00:40,000 --> 00:00:42,019
but it is important because it is included

17
00:00:42,019 --> 00:00:44,770
in the exam requirements.

18
00:00:44,770 --> 00:00:48,471
So with that, I'm going to give you a few optimization tips

19
00:00:48,471 --> 00:00:50,593
for your Azure environment.

20
00:00:51,810 --> 00:00:54,852
All right. Number one, use ARM templates.

21
00:00:54,852 --> 00:00:56,640
ARM templates are really helpful

22
00:00:56,640 --> 00:01:01,640
because they help us to replicate our resources very fast.

23
00:01:01,680 --> 00:01:03,850
We have our blueprint for how we made

24
00:01:03,850 --> 00:01:06,950
all of the different resources in our environment.

25
00:01:06,950 --> 00:01:08,720
It also helps to give us some control,

26
00:01:08,720 --> 00:01:10,618
because there's something that we can go back with

27
00:01:10,618 --> 00:01:13,205
and we can use to audit and figure out exactly

28
00:01:13,205 --> 00:01:15,350
what we're building and why,

29
00:01:15,350 --> 00:01:18,840
and build some continuity between multiple groups

30
00:01:18,840 --> 00:01:21,253
building resources in Azure.

31
00:01:22,100 --> 00:01:25,330
Second, don't put everything in the same subscription.

32
00:01:25,330 --> 00:01:26,576
I've said this a couple of times,

33
00:01:26,576 --> 00:01:29,210
but it is a very important point.

34
00:01:29,210 --> 00:01:30,540
You don't want to have everything

35
00:01:30,540 --> 00:01:34,080
in the same subscription because, one, defense in depth.

36
00:01:34,080 --> 00:01:36,080
If everything is in the same subscription

37
00:01:36,080 --> 00:01:39,410
and someone gets one of your admin accounts, you're done.

38
00:01:39,410 --> 00:01:41,620
They have access to everything.

39
00:01:41,620 --> 00:01:43,555
If you've built multiple subscriptions,

40
00:01:43,555 --> 00:01:46,950
then they only have access to that 1 subscription.

41
00:01:46,950 --> 00:01:49,290
Or it could be built on dev and production.

42
00:01:49,290 --> 00:01:51,277
So if the dev environment is compromised,

43
00:01:51,277 --> 00:01:53,100
you're still okay in the production.

44
00:01:53,100 --> 00:01:55,480
So don't put everything in the same subscription.

45
00:01:55,480 --> 00:01:57,160
The second reason is compliance.

46
00:01:57,160 --> 00:01:59,738
A lot of times, there's regulatory requirements

47
00:01:59,738 --> 00:02:03,537
for how data is stored in your environment,

48
00:02:03,537 --> 00:02:06,110
and the separation that needs to be there for that.

49
00:02:06,110 --> 00:02:09,700
So make sure that you're looking at compliance as well.

50
00:02:09,700 --> 00:02:11,410
Third is management.

51
00:02:11,410 --> 00:02:13,750
If you built up subscriptions in an appropriate way,

52
00:02:13,750 --> 00:02:14,770
it's going to be easier

53
00:02:14,770 --> 00:02:18,011
for you to manage your environment as well.

54
00:02:18,011 --> 00:02:22,510
Third, Azure Advisor. Hey, this is a must-use.

55
00:02:22,510 --> 00:02:23,710
And since we haven't actually

56
00:02:23,710 --> 00:02:25,900
talked about Azure Advisor all that much,

57
00:02:25,900 --> 00:02:27,850
or really I think at all in this course,

58
00:02:27,850 --> 00:02:29,730
I'm going to actually jump into the portal,

59
00:02:29,730 --> 00:02:32,270
and we're going to take a look at Azure Advisor

60
00:02:32,270 --> 00:02:33,430
and how it functions.

61
00:02:33,430 --> 00:02:35,030
So let's just go ahead and do that,

62
00:02:35,030 --> 00:02:38,040
and I'll explain what it is as we go.

63
00:02:38,040 --> 00:02:40,506
So here we find ourselves in the Azure portal,

64
00:02:40,506 --> 00:02:41,962
and let's just go ahead

65
00:02:41,962 --> 00:02:45,920
and open up my Synapse workspace that we've been looking at.

66
00:02:45,920 --> 00:02:48,630
And you can see here, in our Synapse workspace,

67
00:02:48,630 --> 00:02:51,580
if I scroll down under Monitoring,

68
00:02:51,580 --> 00:02:54,400
there is Advisor Recommendations.

69
00:02:54,400 --> 00:02:55,770
This is something that you should be

70
00:02:55,770 --> 00:02:57,580
periodically looking at.

71
00:02:57,580 --> 00:02:58,910
It's going to be very helpful,

72
00:02:58,910 --> 00:03:00,140
and it's going to highlight anything

73
00:03:00,140 --> 00:03:02,150
that you have wrong in your environment,

74
00:03:02,150 --> 00:03:05,090
or ways that you can optimize as well.

75
00:03:05,090 --> 00:03:06,810
Now, we can access Advisor

76
00:03:06,810 --> 00:03:11,165
not just by going to the resource that we're interested in,

77
00:03:11,165 --> 00:03:14,023
but we can also search for Advisor,

78
00:03:14,930 --> 00:03:16,400
and I can go to it here.

79
00:03:16,400 --> 00:03:17,820
And this will pull up Advisor

80
00:03:17,820 --> 00:03:20,320
about my entire environment.

81
00:03:20,320 --> 00:03:21,610
And so if I want to see,

82
00:03:21,610 --> 00:03:22,640
you can see I have a couple of

83
00:03:22,640 --> 00:03:24,100
different recommendations here.

84
00:03:24,100 --> 00:03:26,950
If I clicked on that, it pulls up and it gives me

85
00:03:26,950 --> 00:03:29,600
a little bit of information on what's going on.

86
00:03:29,600 --> 00:03:34,130
So it wants me to add a policy to

87
00:03:34,130 --> 00:03:36,582
audit VMs that don't use managed disks, right?

88
00:03:36,582 --> 00:03:39,110
Now, for my case, I don't really care.

89
00:03:39,110 --> 00:03:42,569
This is for a course that's going away.

90
00:03:42,569 --> 00:03:45,100
So all of this environment's going to go away here.

91
00:03:45,100 --> 00:03:48,800
So it's not a huge concern because I'm not really using VMs,

92
00:03:48,800 --> 00:03:51,251
but it's something worth reading through.

93
00:03:51,251 --> 00:03:55,550
Also, enforce inherit a tag from the resource group.

94
00:03:55,550 --> 00:03:57,930
We've talked about how important tagging is.

95
00:03:57,930 --> 00:04:00,730
If this was a real production, or even a dev environment,

96
00:04:00,730 --> 00:04:03,010
this would be something I'd want to look at.

97
00:04:03,010 --> 00:04:05,730
So make sure that you're looking at Advisor,

98
00:04:05,730 --> 00:04:07,510
that's going to be very helpful for you

99
00:04:07,510 --> 00:04:09,890
as you move forward in your career.

100
00:04:09,890 --> 00:04:11,599
With that, let's do just a couple of key points

101
00:04:11,599 --> 00:04:13,750
to remember to close this out.

102
00:04:13,750 --> 00:04:15,640
First, think holistically.

103
00:04:15,640 --> 00:04:17,218
We've talked about this in the course.

104
00:04:17,218 --> 00:04:20,960
All of these concepts should blend together

105
00:04:20,960 --> 00:04:24,570
into 1 large picture of data management.

106
00:04:24,570 --> 00:04:27,230
So thinking about your ARM templates,

107
00:04:27,230 --> 00:04:29,910
that's an important piece of data management.

108
00:04:29,910 --> 00:04:31,624
Thinking about your security,

109
00:04:31,624 --> 00:04:33,854
data management, that's importance.

110
00:04:33,854 --> 00:04:37,000
So thinking about all of those different components,

111
00:04:37,000 --> 00:04:38,980
and not just the data is going to help you

112
00:04:38,980 --> 00:04:41,730
be a better data engineer.

113
00:04:41,730 --> 00:04:46,080
Next, for the DP-203, assume a very small application.

114
00:04:46,080 --> 00:04:47,460
This is something that's going to be helpful

115
00:04:47,460 --> 00:04:49,160
for you to have a background on.

116
00:04:49,160 --> 00:04:50,980
It's helpful because it was included

117
00:04:50,980 --> 00:04:52,210
in the exam requirements,

118
00:04:52,210 --> 00:04:54,410
but I wouldn't spend a whole lot of time here,

119
00:04:54,410 --> 00:04:55,300
because I'm not expecting

120
00:04:55,300 --> 00:04:58,010
a whole bunch of questions on the DP-203.

121
00:04:58,010 --> 00:04:59,398
So with that, let's stop talking,

122
00:04:59,398 --> 00:05:01,113
and I'll you see in the next video.
