Introduction to AWS Networking

AWS offers a robust networking infrastructure that allows you to connect and manage your resources in the cloud. In this section, we will provide an overview of AWS networking and the basic components involved.

Networking Fundamentals

Before diving into AWS networking, it is essential to understand some networking fundamentals:

• IP Address: An IP address is a unique identifier assigned to each device on a network. It allows devices to communicate with each other.

• Subnet: A subnet is a range of IP addresses within a larger network. It helps in organizing and segmenting a network.

• Internet Gateway: An internet gateway is a horizontally scalable, highly available VPC component that allows communication between instances in your VPC and the internet.

AWS Networking Components

AWS provides several networking components that enable you to build and manage your network infrastructure:

• Virtual Private Cloud (VPC): A VPC is a logically isolated section of the AWS cloud where you can launch AWS resources in a virtual network.

• Subnet: In AWS, a subnet is a range of IP addresses in your VPC. It can be either a public or private subnet.

• Route Table: A route table is a set of rules defined for routing network traffic within a VPC.

• Security Group: A security group acts as a virtual firewall for your EC2 instances, controlling inbound and outbound traffic at the instance level.

• Network Access Control List (NACL): A NACL is an optional layer of security for your VPC that acts as a firewall for controlling traffic in and out of one or more subnets.

• Elastic Load Balancer (ELB): ELB automatically distributes incoming application traffic across multiple targets, such as EC2 instances, containers, and IP addresses.

Now that we have covered the basics, let's dive deeper into each component and learn how they work together to build a secure and scalable network.

    // replace with your Java logic here

    System.out.println("Welcome to AWS Networking!");
