What is Amazon VPC ? and how to create it

Amazon VPC is virtual network provided by AWS.
VPC stands for Virtual Private Cloud.
You can create a web services in VPC, and you can　also connect VPC to Internet.

In this post I will explain how to create a VPC with your AWS account.

At first you have to choose VPC in your AWS management console ,and next tap the "create VP" button.

After you tapped "create VPC" , you have to set CIDR block to reserve IP address for your VPC.

In this part , you may realize the notation "/24".
IP address is a binary number with 32 digits.
"/24" means the first 24 digits in this IP address is fixed , and the rest 8(32-24) digits are unfixed.

So with the address 172.16.1.0/24 ,you can reserve IP address ranging from 172.16.1.0 to 172.16.1.255 .

After you set the CIDR block , click the "create VPC" in button right bottom.
Now you have created one VPC.
