AWS Networking

In AWS, networking plays a crucial role in connecting and isolating resources within different components of the infrastructure. To understand how networking works in AWS, let's explore some key components:

Virtual Private Cloud (VPC)

A Virtual Private Cloud (VPC) is a virtual network dedicated to your AWS account. It provides a logically isolated section of the AWS cloud where you can launch AWS resources.

1Vpc vpc = new Vpc();
2vpc.setName("MyVPC");
3vpc.setCidrBlock("10.0.0.0/16");

In the above example, we create a VPC with the name "MyVPC" and the CIDR block "10.0.0.0/16". This allows us to define the IP address range for the VPC.

Virtual Private Gateway (VPG)

A Virtual Private Gateway (VPG) is a VPN connection that enables communication between your VPC and your on-premises network.

1Vpg vpg = new Vpg();
2vpg.setName("MyVPG");
3vpg.setVpc(vpc);

In the above example, we create a VPG with the name "MyVPG" and associate it with the VPC we created earlier.

Peering Connection

A peering connection allows you to connect one VPC with another VPC within the same AWS region.

1Peering peering = new Peering();
2peering.setName("MyPeering");
3peering.setVpg(vpg);
4peering.setPeerVpc(vpc);

In the above example, we create a peering connection with the name "MyPeering" and associate it with the VPG and the peer VPC.

By understanding these networking components in AWS, you can effectively design and configure your infrastructure to meet your specific networking requirements.

public class NetworkExample {

    public static void main(String[] args) {

        // Create a VPC

        Vpc vpc = new Vpc();

        vpc.setName("MyVPC");

        vpc.setCidrBlock("10.0.0.0/16");

​

        // Create a VPG

        Vpg vpg = new Vpg();

        vpg.setName("MyVPG");

        vpg.setVpc(vpc);

​

        // Create peering connection

        Peering peering = new Peering();

        peering.setName("MyPeering");

        peering.setVpg(vpg);

        peering.setPeerVpc(vpc);

​

        // Print information

        System.out.println("VPC: " + vpc.getName());

        System.out.println("VPG: " + vpg.getName());

        System.out.println("Peering: " + peering.getName());

    }
