If you want to connect multiple VPCs, and you have two or three VPCs, do you have to connect EC2 to each VPC? How can you achieve that?

Question

Accepted Answer

To connect multiple VPCs, we can use VPC peering or VPN connections.

Create a VPC peering connection between the VPCs
Configure route tables to allow traffic between the VPCs
Alternatively, create VPN connections between the VPCs
Attach EC2 instances to the appropriate VPCs

Accepted Answer

To connect multiple VPCs, you can use VPC peering, Transit Gateway, or other networking solutions provided by AWS. Here's a brief overview of how to do it:

VPC Peering:
- Set up VPC peering connections between each pair of VPCs you want to connect. This allows direct communication between instances in the peered VPCs.
Transit Gateway:
- Create a Transit Gateway and attach the VPCs to it. This simplifies the network architecture and allows for centralized connectivity between multiple VPCs.

Remember to configure the appropriate route tables, security groups, and network ACLs to allow traffic flow between the VPCs.
