It was a similar question to asking "What if a Google Ad doesn't work?" And I'm saying that there will obviously be a time when an attempt to promote something doesn't get traction. What we can do is give our best effort to make sure that it does by making sure it's relevant to the people reading it and not just spam that disrespects people's attention
I tried but seems aws has closed the door. To connect ec2 to Lightsail via private IP I have to create a "ec2-classic VPC" in ec2. But aws has disabled "ec2-classic VPC" in all regions
From what I know is that you can peer the Lightsail (AWS-managed) VPC with your normal, default EC2 VPC via the Lightsail console. Then you launch EC2 instances in the default VPC for the transfer
This pricing only seems make sense when the two instances are belong to different owners that are billed $0.01/GB both. But still ridiculous: Data transfer in from internet is free, but from another zones/regions cost $0.01. Maybe they just want to make the pricing "look cheaper"?
