AWS Subnet and Access
This lesson is part of AWS · All levels
Summary
The subnet divides VPC into smaller network segments, namely the public subnet that has a connection to the internet and the private subnet that does not. The route table setting determines where traffic is directed, while the Security Group and Network ACL maintain traffic safety. This combination allows you to apply the principle of least privilege to the network.
Key points
- Public subnet is connected to the internet gateway, private subnet is not
- Route table determines the destination of network traffic
- Security Group works at instance level and is stateful
- Network ACL works at subnet level and is stateless
