Default vs. custom Amazon VPC

Default Amazon VPC

Automatic creation with AWS-assigned IP addresses
Pre-configured settings with a subnet in every availability zone
Communicate with the internet by default

Default vs. custom Amazon VPC

Custom Amazon VPC

User-defined
Customize IP address range, subnets, and route tables
Require explicit configuration for internet access
