1
00:00:00,130 --> 00:00:02,520
So let's go ahead and create our first VPC.

2
00:00:02,520 --> 00:00:03,840
Now we could launch the VPC Wizard,

3
00:00:03,840 --> 00:00:05,400
but that would defeat the point of learning.

4
00:00:05,400 --> 00:00:08,900
So what we'll have to do is create everything one-by-one.

5
00:00:08,900 --> 00:00:10,130
So let's go into VPC.

6
00:00:10,130 --> 00:00:11,170
I have one VPC available,

7
00:00:11,170 --> 00:00:13,500
but I'm going to create a new VPC.

8
00:00:13,500 --> 00:00:16,079
And the name tag is going to be DemoVPC.

9
00:00:16,079 --> 00:00:18,250
Here we need to choose an iPv4 CIDR block.

10
00:00:18,250 --> 00:00:23,150
So I will choose 10.0.0.0/16, which is allowed.

11
00:00:23,150 --> 00:00:25,860
So, if we look at the CIDR here and calculate it,

12
00:00:25,860 --> 00:00:28,090
that means that my First IP is this one,

13
00:00:28,090 --> 00:00:29,670
and my Last IP is this one.

14
00:00:29,670 --> 00:00:32,619
We have 65,000, or so, IPs in this range.

15
00:00:32,619 --> 00:00:34,810
So, if I did /15, this would not work

16
00:00:34,810 --> 00:00:37,448
because this would be a too big of a network, okay?

17
00:00:37,448 --> 00:00:40,430
/16 is the limit for your CIDR site.

18
00:00:40,430 --> 00:00:43,350
So for now we are not going to assign any iPv6 CIDR block.

19
00:00:43,350 --> 00:00:45,220
We'll see this later on in the section.

20
00:00:45,220 --> 00:00:46,120
In terms of tenancy,

21
00:00:46,120 --> 00:00:47,510
we have Default or Dedicated.

22
00:00:47,510 --> 00:00:49,900
And this is to define how EC2 instances launch

23
00:00:49,900 --> 00:00:51,550
within this VPC.

24
00:00:51,550 --> 00:00:55,430
We'll have either dedicated hardware or shared hardware.

25
00:00:55,430 --> 00:00:56,940
Now, dedicated hardware is very expensive.

26
00:00:56,940 --> 00:00:59,280
So we are going to have shared hardware by default.

27
00:00:59,280 --> 00:01:01,570
So tenancy is Default.

28
00:01:01,570 --> 00:01:04,050
So Tags is named DemoVPC. This is good.

29
00:01:04,050 --> 00:01:05,560
Now we'll create this VPC.

30
00:01:05,560 --> 00:01:07,970
And my VPC is created.

31
00:01:07,970 --> 00:01:09,170
So if we look at this VPC,

32
00:01:09,170 --> 00:01:14,170
as we can see we have one iPv4 CIDR, zero iPv6 CIDR, okay?

33
00:01:14,370 --> 00:01:16,190
We have already a main route table

34
00:01:16,190 --> 00:01:17,900
and a main network ACL associated with it.

35
00:01:17,900 --> 00:01:20,350
So some stuff was created behind the scenes,

36
00:01:20,350 --> 00:01:21,940
when we created the VPC.

37
00:01:21,940 --> 00:01:22,910
And something we should notice is

38
00:01:22,910 --> 00:01:25,680
that we are able to add other iPv4 CIDRs.

39
00:01:25,680 --> 00:01:29,930
So in the creates dialogue, we could only specify one,

40
00:01:29,930 --> 00:01:33,210
But if I do Action and then Edit CIDRs,

41
00:01:33,210 --> 00:01:35,480
and then here, I could add a new IPv4 CIDR.

42
00:01:35,480 --> 00:01:40,480
So I could have 10.0.0, sorry, .1.0/, excuse me,

43
00:01:40,850 --> 00:01:44,720
10.1.0.0/16, which is the next CIDR after this one.

44
00:01:44,720 --> 00:01:45,553
And then click on Save.

45
00:01:45,553 --> 00:01:47,840
So we could have two different CIDRs in here.

46
00:01:47,840 --> 00:01:50,580
And you could also add different IPv6 CIDRs.

47
00:01:50,580 --> 00:01:51,710
Now to keep it very simple,

48
00:01:51,710 --> 00:01:54,343
I'm not going to have two IPv4 CIDRs.

49
00:01:54,343 --> 00:01:55,200
I'm just going to have one.

50
00:01:55,200 --> 00:01:56,720
But I'm going to show you that you can have

51
00:01:56,720 --> 00:02:01,720
up to five IPv4 CIDRs within your VPC, which is quite handy.

52
00:02:02,010 --> 00:02:04,160
Okay, so we have this DemoVPC being created.

53
00:02:04,160 --> 00:02:05,610
This is our first step to our demo.

54
00:02:05,610 --> 00:02:06,443
I hope you liked it.

55
00:02:06,443 --> 00:02:08,250
And I will see you in the next lecture.
