AWS VPC to VPC Peering in two different regions | Cross region VPC Peering | Hindi

Absolutely, VPC peering can be established between VPCs in two different regions, also known as inter-region VPC peering. This allows resources in each VPC to communicate securely using private IP addresses, without needing a public internet connection or a VPN.

Here's a breakdown of the benefits and process for creating an inter-region VPC peering connection:

*Benefits:*

*Private Communication:* Resources in the peered VPCs can communicate directly using private IP addresses, enhancing security.
*Scalability:* VPC peering facilitates data transfer between resources in separate regions, enabling easy scaling of your application across regions.
*Lower Cost:* Eliminates the need for internet gateways or VPN connections, potentially reducing network egress costs.

*Process:*

1. *Initiating the Peering Request:*
Go to the VPC console in the region of the "requester" VPC (the VPC initiating the connection).
Select "Peering connections" and choose "Create peering connection".
Configure the connection details, specifying the "accepter" VPC ID (the VPC in the other region) and optionally assigning a name.

2. *Accepting the Peering Request:*
Log in to the VPC console in the region of the "accepter" VPC.
Navigate to "Peering connections" and select the received request.
Review the details and click "Accept peering connection" to establish the connection.

3. *Updating Route Tables:*
In both VPCs, update the route tables to include routes for the peered VPC's CIDR block. This directs traffic destined for the peered VPC to the VPC peering connection.
