Frequently Asked Questions
What is a VPC?
A Virtual Private Cloud is a logically isolated network inside a public cloud, where you define subnets, routing tables and access rules that control how your resources communicate.
What is the difference between security groups and network ACLs?
Security groups are stateful rules attached to resources, while network ACLs are stateless rules applied at the subnet level. Using both gives layered control over traffic.
What are common VPC misconfigurations?
Examples include open security groups, public subnets for private workloads, unrestricted outbound traffic and missing flow logs. This free intermediate room on Codelivly shows how to find and fix them.
