Hi, so a very short lecture

2
00:00:02,310 --> 00:00:04,680
on an architecture that can come up in the exam.

3
00:00:04,680 --> 00:00:07,860
So the idea is that you have your corporate data center

4
00:00:07,860 --> 00:00:11,100
and it's connected to your VPC using Direct Connect.

5
00:00:11,100 --> 00:00:13,140
And that's your primary connection

6
00:00:13,140 --> 00:00:15,750
and it's expensive, but maybe sometimes

7
00:00:15,750 --> 00:00:18,570
you will have an issue with your Direct Connect connection,

8
00:00:18,570 --> 00:00:20,880
and of course, you do not want to have

9
00:00:20,880 --> 00:00:24,330
no internet connection into your VPC.

10
00:00:24,330 --> 00:00:26,850
Therefore, you can use a Direct Connect

11
00:00:26,850 --> 00:00:28,950
as a secondary connection,

12
00:00:28,950 --> 00:00:30,990
but that would be quite expensive.

13
00:00:30,990 --> 00:00:34,050
Or you can set up a site to site VPN connection

14
00:00:34,050 --> 00:00:35,460
as a backup connection

15
00:00:35,460 --> 00:00:38,850
and set it up so that if the primary connection fails,

16
00:00:38,850 --> 00:00:41,550
then it kicks in, and now you are connected

17
00:00:41,550 --> 00:00:44,880
through the public internet using site to site VPN,

18
00:00:44,880 --> 00:00:47,100
which can be a bit more reliable

19
00:00:47,100 --> 00:00:49,230
because the internet, public internet,

20
00:00:49,230 --> 00:00:51,360
may always be accessible, okay?

21
00:00:51,360 --> 00:00:53,850
So this is an architecture that can come up in the exam

22
00:00:53,850 --> 00:00:55,380
and I just wanted to show it to you once,

23
00:00:55,380 --> 00:00:57,030
so that you know what to expect.

24
00:00:57,030 --> 00:00:58,650
Okay, that's it, I hope you liked it,

25
00:00:58,650 --> 00:01:00,600
and I will see you in the next lecture.
