Is it possible to use VPC to have access between two AWS Regions

Question

My concern circles around two kubernetes clusters. I am aware this can be done using VPN. I wish to know if its possible using VPC. I also wish to know where I put my gateways?

Can this be done?

Answer 1

Good question this. Currently this feature is not a native managed service to AWS. You can however, implement it yourself.

 Rackspace provides a good guide on how to get started for that please refer this link: https://goo.gl/bhVPEC

There are three ways to achieve this:

1. Hardware: Here you need a router in your own datacentre, now maintain one ipsec tunnel to a VGW in VPC-Region A and a second ipsec tunnel to a VGW in VPC-Region B. The VGW stands for Virtual Private Gateway, basically a vpn concentrator on the AWS side of the connection. The Customer Gateway would be the router in your own datacentre.
2. Software: You can use  openswan to hook up a ipsec tunnel between VPC-Region A and VPC-Region B. refer this AWS doc:  https://goo.gl/9u5ei6
3. Combination: A combination of the above two approaches, where you can have a instance running Sophos UTM (or similar software) in VPC-Region A connect by ipsec tunnel to a VGW in VPC-Region B. This is explained in the AWS doc: https://goo.gl/em1Njp

You will need VPC pairing refer this for the same: https://goo.gl/nZE7uR
