AWS Networking
AWS Tutorial: Introduction to AWS Networking (VPC)
Welcome to the AWS Networking lesson. Whenever you deploy a server in the cloud, it must live inside a secure, logically isolated network. In AWS, this is known as a Virtual Private Cloud (VPC).
Why Learn AWS Networking?
Security starts at the network layer. If you don't understand how VPCs work, you might accidentally expose highly sensitive databases directly to the public internet! Learning VPCs is mandatory for securing cloud architectures.
Tutorial Overview
In this tutorial, you will learn:
- What an Amazon VPC is.
- How it logically isolates your AWS resources.
What is an Amazon VPC?
Amazon Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define.
You have complete control over your virtual networking environment:
- IP Addressing: You choose your own IP address ranges (CIDR blocks).
- Subnets: You partition your VPC into smaller networks.
- Route Tables & Gateways: You configure exactly how traffic enters, exits, and moves around within the network.
By default, when you create an AWS account, AWS provides a "Default VPC" in every region so you can launch EC2 instances immediately without knowing complex networking.
