As long as you use private IP addresses, AWS-AWS traffic is free[0]. However: Lightsail instances don't show up as EC2 instances nor can you add them to a VPC.

As long as you use private IP addresses, AWS-AWS traffic is free[0]. However: Lightsail instances don't show up as EC2 instances nor can you add them to a VPC. Meaning that your AWS resources need to be in EC2 classic in order to have free transfer between them. And even then, you would need to do it with VPN tunnels to get there. Still, could be worth it.

- koolba 10y agoAny idea if S3 => Lightsail bandwidth is free? If so then that might be an interesting play. It'd be relatively straightforward to put a proxy in front of S3. It'd end up be 19x cheaper (pool of 1TB @ $5 Lightsail servers) for bandwidth on the low end and 5.5x cheaper on the high end (pool of 5TB @ $80 Lightsail servers). Compare that to $90 / TB for standard S3 outbound to internet pricing!
