Key Takeaways
- ā¢VPC provides isolated network environment with public/private subnets, route tables, and internet/NAT gateways
- ā¢Security Groups (stateful, instance-level) vs NACLs (stateless, subnet-level) provide layered network security
- ā¢VPC Peering connects VPCs privately, VPC Endpoints access AWS services without internet gateway
- ā¢Site-to-Site VPN (encrypted over internet) vs Direct Connect (dedicated private connection) for hybrid cloud
- ā¢NAT Gateway (AWS-managed, highly available) recommended over NAT Instance for private subnet internet access
