1
00:00:00,140 --> 00:00:01,620
So let's go ahead with creating

2
00:00:01,620 --> 00:00:03,020
our first VPC in AWS.

3
00:00:03,020 --> 00:00:06,090
So VPC stands for Virtual Private Cloud.

4
00:00:06,090 --> 00:00:09,010
And you can have multiple VPC within a single AWS region.

5
00:00:09,010 --> 00:00:10,770
You could have a maximum of five per region,

6
00:00:10,770 --> 00:00:13,350
but this is a soft limit, so you can increase it.

7
00:00:13,350 --> 00:00:17,680
And the number of CIDRs assigned per VPC is five.

8
00:00:17,680 --> 00:00:20,540
Now for each CIDR, the minimum size is /28,

9
00:00:20,540 --> 00:00:23,320
so that means at least 16 IP addresses.

10
00:00:23,320 --> 00:00:26,020
The maximum size is /16, which is at max

11
00:00:27,242 --> 00:00:29,750
65,536 IP addresses.

12
00:00:29,750 --> 00:00:32,860
And because VPC is a private resource,

13
00:00:32,860 --> 00:00:35,000
only Private IPv4 ranges are allowed.

14
00:00:35,000 --> 00:00:37,030
So again, as a reminder, we have this range,

15
00:00:37,030 --> 00:00:39,370
that range, and that range.

16
00:00:39,370 --> 00:00:41,970
Now how do we choose the range for our VPC

17
00:00:41,970 --> 00:00:45,180
in terms of what types of VP are we going to assign to it?

18
00:00:45,180 --> 00:00:46,740
Well, the general rule is that you can assign

19
00:00:46,740 --> 00:00:48,710
whatever you want, but you should make sure

20
00:00:48,710 --> 00:00:51,200
that your VPC CIDR does not overlap

21
00:00:51,200 --> 00:00:54,220
with your other VPCs or other networks

22
00:00:54,220 --> 00:00:56,130
or corporate networks, and the reason we do so

23
00:00:56,130 --> 00:00:57,950
is that if you want to connect them together,

24
00:00:57,950 --> 00:00:59,340
we want to make sure the IP addresses

25
00:00:59,340 --> 00:01:02,060
of one VPC or one CIDR do not overlap

26
00:01:02,060 --> 00:01:05,060
with the range of IP addresses of other networks.

27
00:01:05,060 --> 00:01:06,370
So at the end of this hands-on,

28
00:01:06,370 --> 00:01:09,360
we're just going to have within a region a simple VPC.

29
00:01:09,360 --> 00:01:10,410
So let's get started.
