En VPC (Virtual Private Cloud) er dit eget isolerede virtuelle netværk inden for AWS — hvor du starter ressourcer (som EC2-instanser) med kontrol over IP-intervaller, subnets, routing og sikkerhed. Det er netværksgrundlaget for AWS-ressourcer.
Hvad en VPC er
A VPC is a logically ISOLATED virtual network in AWS that YOU control:
→ define your IP address range (CIDR block, e.g. 10.0.0.0/16)
→ divide it into SUBNETS; control ROUTING and security
→ your resources (EC2, RDS, etc.) live inside it, isolated from other networks
→ Like having your own private network in the cloud.
