How AWS Lightsail bandwidth pricing works

So on the AWS Lightsail page there is a part which says only outbound transfer in excess of allowance is charged.

But in another part of the Lightsail pricing page it says that both inbound AS WELL AS outbound use up your transfer allowance.

Putting the two pieces of information together, it means that both inbound as well as outbound will use up your allowance. But once you have used up your allowance, you will only get charged for the outbound traffic.

So for example, if you pay $3.50 per month then you'll get the 1TB allowance.

So if you do 1TB of ingress followed by 1TB of egress, then the first 1TB of ingress will use up all of your bandwidth allowance, and then the 1TB of egress will be charged at the standard AWS rate of $0.09 per GB which comes out to $90.

Just thought I'd explain this for anyone else who was confused about the Lightsail pricing like I was.

By contrast, many big VPS providers such as Digital Ocean, Linode, Vultr, Contabo, and so on do not charge for ingress at all. Digital Ocean explicitly says "Any inbound transfers don't count against your bandwidth usage."

HOWEVER, I signed up for Vultr wanting to buy their $3.50 plan and later found out that it's only available in one location in the US. I thought their $3.50 plan was available in all locations. Keep this in mind because when you sign up for Vultr you have to buy some credit. I would suggest not putting in any credit until you're sure that the plan you want to buy is actually available.
