Main Advantages of Using Transit Gateway in Amazon AWS

  • Per region VPN Tunnels: Instead of building tunnels every time we a new VPC is created . It allows to simply attach the VPC to the transit gateway within the region which will already have a VPN established. Once attached, it will simply be a matter of adding routing propagations to establish the connectivity of the VPC with VPN.

  • Attach to Transit Gateway once rather than peer to multiple VPCs: Every time a new VPC is created , It often times required to peer that VPC with other accounts and shared environments. With the Transit gateway, you can simply attach the VPC to the transit gateway and associate that attachment with the right routing domain and allow routes to propagate which will give that new VPC access to multiple VPCs and vice-versa. 

The known limitation of the AWS Transit gateway is the fact that it does not support the cross region support for which Inter-region Vpc peering is required. Though is in the future pipeline and rather the correct direction to be implemented once the AWS releases this functionality in the near future.

The best practice to deploy the AWS transit gateway is by using the Infrastructure as code practices tool like Terraform. Code i will share in the future post so stay tuned and subscribe to our blog.
