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.

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.

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.

One data center can connect hardware VPN with AWS VPC. AWS supports internet protocol security VPN connections only. The encrypted data will be transferred. VPN connection helps in data security while transiting. No internet gateway is required to establish a hardware VPN connection with AWS VPC.

Beginners who were trying AWS VPC interview questions for the first time used to get confused with this question, since these terms look similar.
Actually, VPS or Virtual Private Server is none other than the host server offered by web hosting companies like BlueHost and GoDaddy (These companies also provide shared hosting services wherein the server is shared by several users). Here, a single host divided to multiple virtual units, each having an independent function. Each of these units is virtual private servers which can work without depending on one another. You’ll get access to the complete physical server including root access.
In the case of VPC, its functions are similar to that of a VPS but its servers don’t have to place in a single location.
