VPN for vpc

You can create a vpn connection from your corporate network and one vpc, but very oftnet you need to have multiple VPCs and you can't create multiple vpn conncetions because it requires manual action on phisical routers and also multiple public ip on premise site ecc.

In this article there are some solutions proposed https://aws.amazon.com/answers/networking/aws-multiple-vpc-vpn-connection-sharing/

  1. Use Direct Connect, this solution is more complex and also expensive than a VPC VPN solutions but also very powerful
  2. Use a Shared Services VPC , this means have one VPC with the VPN and in this VPC there are only proxy http/socks to connect from AWS to your company
  3. Transit VPC , one VPC with VPN and inside some ec2 machines that acts like routers, it is possible buy this on marketplace to have very good products
  4. Shared Service and Transit VPCs, mix the two solutions
