# Demonstration of VPC Peering.

**VPC peering** is a valuable networking connection that enables two distinct VPCs to securely share resources creating the illusion of being on the same network.

This capability is crucial as it provides a cost-effective solution for resource sharing between multiple VPCs located in the same or different regions eliminating the need for internet gateways. Additionally, by not relying on public IP addresses or internet access VPC peering enhances security measures.

### <mark>Let's begin the Demonstration.</mark>

Step 1: Go to the **AWS management console** search for **VPC**, and click on it.

Step 3: From **VPC settings**

* select **VPC only**
    
* Enter the name of VPC. For now, say **<mark>“my-vpc1"</mark>**
    
* Enter IPv4 CIDR <mark>10.0.0.0 /16</mark>
    
* Click on **Create VPC**
