1
00:00:00,940 --> 00:00:05,390
The tool that you need to know for the exam is App Service Migration Assistant,

2
00:00:05,390 --> 00:00:09,620
and this is a Windows desktop application that can largely automate

3
00:00:09,620 --> 00:00:13,680
assessing your IIS web app suitability for Azure App Service.

4
00:00:13,680 --> 00:00:18,860
Now the assessment is going to look at the entire ecosystem of your local app,

5
00:00:18,860 --> 00:00:22,140
things like port bindings, protocols, certificates,

6
00:00:22,140 --> 00:00:25,360
how you have authentication setup, app settings,

7
00:00:25,360 --> 00:00:27,470
database connection strings,

8
00:00:27,470 --> 00:00:31,430
and what's cool is that you can take advantage of that assessment,

9
00:00:31,430 --> 00:00:35,830
and that will guide you to right size your app service plan when

10
00:00:35,830 --> 00:00:38,340
you undertake the actual migration.

11
00:00:38,340 --> 00:00:40,920
Now this App Service Migration Assistant,

12
00:00:40,920 --> 00:00:46,220
it's not meant for massive scale because it is a single Windows desktop app,

13
00:00:46,220 --> 00:00:46,860
and also,

14
00:00:46,860 --> 00:00:49,780
because it's relatively early days at this time as of

15
00:00:49,780 --> 00:00:52,530
this recording in early Summer 2022,

16
00:00:52,530 --> 00:00:56,690
only ASP.NET and PHP applications are supported now,

17
00:00:56,690 --> 00:00:59,940
but I would expect that in time,

18
00:00:59,940 --> 00:01:03,340
we'll find that App Service Migration Assistant supports all of

19
00:01:03,340 --> 00:01:05,340
the frameworks that App Service supports.

20
00:01:05,340 --> 00:01:09,300
App Service supports ASP with .NET Core,

21
00:01:09,300 --> 00:01:12,890
it supports Python and Java and Node,

22
00:01:12,890 --> 00:01:15,380
there is a bunch of other frameworks that are supported,

23
00:01:15,380 --> 00:01:17,080
so be on the lookout for that.

24
00:01:17,080 --> 00:01:19,240
And then, but wait, there is more.

25
00:01:19,240 --> 00:01:22,660
The assistant can actually perform the migration as well.

26
00:01:22,660 --> 00:01:24,820
So it's a really nice desktop app.

27
00:01:24,820 --> 00:01:26,870
You can't beat the price, it's free.

28
00:01:26,870 --> 00:01:29,090
And I want to just give you a little extra tidbit

29
00:01:29,090 --> 00:01:32,680
because if you're thinking well, what about my SQL Server databases?

30
00:01:32,680 --> 00:01:36,860
There is an analogous migration assistant called the Data Migration Assistant,

31
00:01:36,860 --> 00:01:43,310
or DMA, that does the same stuff, but on SQL Server databases and migrating into,

32
00:01:43,310 --> 00:01:48,100
for instance, Azure SQL database or Azure SQL managed instance.

33
00:01:48,100 --> 00:01:50,040
Isn't that awesome?

34
00:01:50,040 --> 00:01:51,410
I'm going to do a demo on this,

35
00:01:51,410 --> 00:01:56,210
but the high‑level process overview for App Service Migration works like this.

36
00:01:56,210 --> 00:01:58,920
First, you install the assistant, like I said,

37
00:01:58,920 --> 00:02:02,120
it's a desktop app that you can install on your Windows 10,

38
00:02:02,120 --> 00:02:07,240
Windows 11 workstation or the web server with whatever you want to do.

39
00:02:07,240 --> 00:02:09,620
Of course, you'll create an assessment project,

40
00:02:09,620 --> 00:02:12,240
you will correct any warnings and errors,

41
00:02:12,240 --> 00:02:17,710
and then the assessment tool will generate deployment templates that

42
00:02:17,710 --> 00:02:20,830
can help automate the deployment of the App Service,

43
00:02:20,830 --> 00:02:23,360
the App Service plan, and so on, and so forth.

44
00:02:23,360 --> 00:02:25,190
Once you have the app re‑hosted,

45
00:02:25,190 --> 00:02:27,150
it's going to be a question of tweaking and

46
00:02:27,150 --> 00:02:29,760
customizing your Azure App Service Settings,

47
00:02:29,760 --> 00:02:32,920
making sure that you're TLS SSL certificates there,

48
00:02:32,920 --> 00:02:35,440
that you've got your custom domain bind,

49
00:02:35,440 --> 00:02:37,440
you know, all of that kind of stuff.

50
00:02:37,440 --> 00:02:42,450
And then over time, this last step would pertain to any Azure application.

51
00:02:42,450 --> 00:02:45,160
You're going to be monitoring for app availability,

52
00:02:45,160 --> 00:02:49,760
security and performance using tools like Azure Application Insights,

53
00:02:49,760 --> 00:02:53,850
Azure Monitor, Log Analytics, Microsoft Sentinel,

54
00:02:53,850 --> 00:03:00,000
Microsoft Defender for Cloud, etc, etc. Now let's get into that first demo.
