Internet Gateway

Network

An internet gateway (IGW) allows resources associated with public IP (IPv4 or IPv6 address) within your VPC to access the internet. Likewise, resources on the internet can initiate a connection to resources in your subnet using the public IPv4 address or IPv6 address.

Costs

The cost of using an Internet Gateway is determined by the amount of data processed through it, with no additional charges for creation or deletion of the Internet Gateway. The cost starts at $0.05 per GB of data processed and decreases as data processed increases.
