If we want to build up our custom VPC, please follow the given below steps:
First, we need to create a virtual private cloud.
After that need to create subnets.
Now need to create an internet gateway.
Need to attach internet gateway with VPC.
Need to create a routing table.
Now add that created gateway in the new route table.
Do subnet association with the routing table.
Need to create a database server for the private subnet and a web server for the public subnet.
Need to create a new secured group of NAT.
Need to add HTTP and HTTPS inbound rules to allow traffic from private subnet IP.
Need to create elastic IP.
Tag this elastic IP with NAT.
Now deactivate the check for NAT.
Need to add this NAT in the base route table initially.

Yes, we can use our existing AMIs in the AWS VPC in the same registered zone.

If you want to connect Amazon EC2-classic instances to VPC, you have to use ClassicLink. This work only within the same region and this makes use of private IP addresses. Its working is simple- you just have to enable ClassicLink in your VPC account and associate a security group from VPC to EC2-classic instance.
This type of questions are the additions AWS VPC interview questions that you shouldn’t miss so prepare yourself with the answer.

Cloud computing is based on Virtual Private Cloud ( VPC). This is the basic foundation of the AWS platform. Any of the advanced services of AWS can not be accessed without a VPC network. You will get a logically isolated section dedicated to a virtual network platform. Through this cloud, businesses can access customer details and data in a single window. It provides innovative new business approaches.

These VPC’s are existing in the AWS roundabout. This AWS around a geographic area. It can be around the world in Amazon's clustered data centers. It is lived in that assigned geographical area only to maintain customer distribution. So that in different areas customers can not set up another VPC in another geographical area.

Yes, VPC works globally. All its components are also working globally. Obviously, they are divided into zone to crate Subnet networks.

Absolutely not. One virtual network is available in Azure, but they are not the same or related. Both of them have a few common features and different key features also.

Amazon has lots of physical data centers throughout the world. Now they were looking forward to creating virtual data centers. These data centers needed virtual networks and virtual network access. To manage this virtual cloud they have created VPC which actually gives access to clients in the virtual network with a private cloud zone. They kept access to other Amazon services.
