Why are subnets created?
Subnetting ensures that traffic destined for a device within a subnet stays in that subnet, which reduces congestion. … However, using a router to move traffic between subnets results in no broadcast traffic or any information that doesn’t need to be routed being moved to other subnets.

What is a private subnet?
Instances in the private subnet are back-end servers that don’t need to accept incoming traffic from the Internet and therefore do not have public IP addresses; however, they can send requests to the Internet using the NAT gateway (see the next bullet). A NAT gateway with its own Elastic IPv4 address.
