00:00:01,140 --> 00:00:03,480
[Autogenerated] thus far in the course we've been in Azure

2
00:00:03,480 --> 00:00:06,610
automation so we've seen some of its capability,

3
00:00:06,610 --> 00:00:10,460
Let's double-click now and there's going to be a little bit of review

4
00:00:10,460 --> 00:00:13,900
from what we did in the previous module here and that's fine because

5
00:00:13,900 --> 00:00:15,990
there's a principle of adult education,

6
00:00:15,990 --> 00:00:19,380
I think repetition is great and repetition is also going to

7
00:00:19,380 --> 00:00:23,440
help you lock in these concepts and skills For your as 800

8
00:00:23,440 --> 00:00:25,460
certification exam success.

9
00:00:25,460 --> 00:00:27,080
But let's look at azure automation,

10
00:00:27,080 --> 00:00:31,630
run books configuration management or cm as a systems engineering

11
00:00:31,630 --> 00:00:35,750
process with the goal of establishing consistency of a product's

12
00:00:35,750 --> 00:00:37,850
attributes throughout its life cycle.

13
00:00:37,850 --> 00:00:42,070
And the Azure automation account is our cloud based our Azure

14
00:00:42,070 --> 00:00:46,080
cloud based configuration management solution for both Windows

15
00:00:46,080 --> 00:00:48,840
and Linux systems in Azure and beyond.

16
00:00:48,840 --> 00:00:51,680
Azure automation relies upon log analytics,

17
00:00:51,680 --> 00:00:54,730
so you'll need a log analytics workspace as well as the log

18
00:00:54,730 --> 00:00:57,100
analytics agent deployed to your machines.

19
00:00:57,100 --> 00:01:00,630
Select capabilities include as we saw in the previous lesson,

20
00:01:00,630 --> 00:01:04,100
update management, inventory, tracking, change tracking,

21
00:01:04,100 --> 00:01:06,570
run books desired state configuration.

22
00:01:06,570 --> 00:01:08,070
There's a lot here indeed.

23
00:01:08,070 --> 00:01:11,480
The hybrid run book worker which you can deliver to your

24
00:01:11,480 --> 00:01:16,820
off cloud machines via an extension, particularly your Azure arc enabled servers,

25
00:01:16,820 --> 00:01:20,080
you can install the run book worker on them to extend.

26
00:01:20,080 --> 00:01:25,050
Azure automation run books into your local data centers or other clouds though.

27
00:01:25,050 --> 00:01:29,840
Azure automation was really built for hybrid cloud configuration management.

28
00:01:29,840 --> 00:01:33,150
Specifically an Azure automation run book is simply a

29
00:01:33,150 --> 00:01:36,380
cloud hosted automation script, you might think well wait a minute,

30
00:01:36,380 --> 00:01:38,760
what's the difference between an Azure automation

31
00:01:38,760 --> 00:01:40,850
run book and an Azure function, aren't they?

32
00:01:40,850 --> 00:01:42,870
Both cloud hosted scripts well,

33
00:01:42,870 --> 00:01:46,080
kind of specifically Azure automation run books are

34
00:01:46,080 --> 00:01:48,800
meant for the IT professional really.

35
00:01:48,800 --> 00:01:52,720
The operations person rather than the developer run books share

36
00:01:52,720 --> 00:01:56,930
similarities with Azure functions in that you can trigger them manually

37
00:01:56,930 --> 00:02:00,680
on a schedule or have them be triggered by an event.

38
00:02:00,680 --> 00:02:04,530
And there is another similarity that both Azure functions and automation

39
00:02:04,530 --> 00:02:07,690
run books support PowerShell or PowerShell workflow.

40
00:02:07,690 --> 00:02:11,580
Workflow is a subset of power Shell's capability that allows

41
00:02:11,580 --> 00:02:14,580
you to do more durable long running processes that

42
00:02:14,580 --> 00:02:16,990
potentially could survive a restart.

43
00:02:16,990 --> 00:02:20,180
Azure automation run books have a graphical option

44
00:02:20,180 --> 00:02:22,200
that you do not get with functions.

45
00:02:22,200 --> 00:02:26,190
Both run books can be python scripts as well as functions.

46
00:02:26,190 --> 00:02:26,700
So yes,

47
00:02:26,700 --> 00:02:30,460
there is some overlap between functions and run books but for

48
00:02:30,460 --> 00:02:33,100
our purposes a hybrid cloud administrator,

49
00:02:33,100 --> 00:02:36,720
we're concerned entirely with Azure automation run books.

50
00:02:36,720 --> 00:02:39,960
So just know about functions and function apps just from a

51
00:02:39,960 --> 00:02:42,430
theoretical standpoint like I mentioned,

52
00:02:42,430 --> 00:02:43,650
the Azure automation.

53
00:02:43,650 --> 00:02:49,030
Hybrid worker is what extends Azure automation run book services off cloud

54
00:02:49,030 --> 00:02:52,930
into your local data center as well as in other environments.

55
00:02:52,930 --> 00:02:55,480
Now there's two types of Azure automation.

56
00:02:55,480 --> 00:02:56,440
Hybrid worker,

57
00:02:56,440 --> 00:03:00,260
there's the system worker that's used and managed only by Azure and

58
00:03:00,260 --> 00:03:02,850
it's used with the update management solution,

59
00:03:02,850 --> 00:03:06,810
but then you can deploy user workers with a purpose like I said,

60
00:03:06,810 --> 00:03:11,140
of extending your Azure automation run book executions to your hybrid cloud,

61
00:03:11,140 --> 00:03:14,240
as you can see I know, the text is small and the diagram.

62
00:03:14,240 --> 00:03:18,140
Right and again, I provide attribution for all of these borrowed diagrams.

63
00:03:18,140 --> 00:03:21,650
We're dealing with TCP 443 and TLS encryption.

64
00:03:21,650 --> 00:03:24,250
So the idea is that you don't need a site to site

65
00:03:24,250 --> 00:03:26,470
VPN or virtual private network,

66
00:03:26,470 --> 00:03:29,640
nor do you need an express route circuit in order to do this.

67
00:03:29,640 --> 00:03:30,560
As I mentioned,

68
00:03:30,560 --> 00:03:35,420
the preferred way to create hybrid worker instances is to deploy

69
00:03:35,420 --> 00:03:38,120
with the hybrid run book worker VM extension.

70
00:03:38,120 --> 00:03:43,120
So ideally your on premises or off cloud machine is arc enabled,

71
00:03:43,120 --> 00:03:47,300
which gives you access to the VM extensions in Azure and you can deploy

72
00:03:47,300 --> 00:03:50,300
the hybrid run book worker directly to that machine.

73
00:03:50,300 --> 00:03:55,210
Lastly, you can create these logical groupings of hybrid worker agents.

74
00:03:55,210 --> 00:03:57,880
These are called hybrid run book worker groups.

75
00:03:57,880 --> 00:04:06,000
And the purpose of this is to provide high availability for your off cloud Azure automation run book jobs.
