AWS VPC Fundamentals

Understanding Amazon VPC

An Amazon Virtual Private Cloud (VPC) allows you to launch AWS resources in a logically isolated section of the AWS Cloud. It is a fundamental building block for most AWS solutions. It enables you to control your own network environment, including your IP address range, subnets, route tables, and network gateways. Think of it as your own private network within the AWS ecosystem.

Key Concepts

• Subnets: Divided your VPC into smaller, isolated network segments. You can have public subnets (accessible from the internet) and private subnets (not directly accessible).
• Route Tables: Determine how traffic is directed within your VPC and to other networks.
• Network Gateways: Connect your VPC to the internet or to an on-premises network.
• Internet Gateway: A virtual networking component that enables communication between your VPC and the public internet.
• NAT Gateway: Allows instances in your private subnets to outbound internet access without being directly exposed to the internet.

Benefits of Using VPCs

* Security: Provides a secure environment for your AWS resources. * Control: Gives you complete control over your network configuration. * Scalability: Easily scale your network to meet your changing needs. * Compliance: Helps you meet regulatory compliance requirements.
