Amazon VPC is web service that allows us to create a private network in the cloud. In this lab,

• Part 1: Deploy VPC with public subnets
• Part 2: Deploy an EC2 instance into VPC

Lab Begins

Part 1: Exploration

VPC

Amazon Virtual Private Cloud is a virtual network that is dedicated to your AWS account

Note: The VPC IPv4 CIDR is 172.31.0.0/16

Subnets

A subnet is a sub-range of IP addresses in the VPC.

Note: Auto-assign public IPv4 address is Yes. The Subnet IPv4 CIDR is 172.31.0.0/20. Since, AWS reserves five addresses in each subnet for it’s own purpose such that only 4091 address are available out of 4096.

Internet Gateway

An internet gateway allows communication between the resources in a VPC and the internet.

Route Table

A route table contains a set of rules, called routes, that are used to determine where network traffic is directed.

Note: 172.31.0.0/16 is routed locally, allowing all subnets in a VPC to communicate with each other and all public traffic (0.0.0.0/0) is routed to the internet gateway.

Security Group

A security group acts as a virtual firewall for instances to control inbound and outbound traffic.
