Amazon VPC | Creating a VPC from Scratch

VPC stands for Virtual Private Cloud , is one of the fundamental and widely used AWS service which provides a virtual network dedicated for the AWS environments. It is logically isolated from the other virtual networks in the Cloud and exists within a single region.

Benefits of using VPC
Define custom network.
Assign static private IPv4 addresses to the instances.
Define network interfaces and attach one of more network interface to the instances.
Define the routing between different subnets.
Define the internet access for the subnets.
Define your network security by allowing/denying the traffic .

LAB
In this lab we are going to create a new VPC . VPC will be having 02 subnets, one subnet will have internet connectivity and second will be without internet connectivity. Both subnets can talk with each other through the default routing table. , but we will allow only specific ports using security groups ( firewall).

VPC Name / CIDR : awslab-vpc 172.16.0.0/16

Subnet Name / CIDR : awslab-subnet-public 172.16.1.0/24
Internet Gateway Connectivity : Yes
Routing Table : awslab-rt-internet

Subnet Name : awslab-subnet-private 172.16.2.0/24
Internet Gateway Connectivity : No
