What is AWS VPC?
An AWS Virtual Private Cloud (VPC) is a logically isolated network inside AWS where you can launch resources such as:
- EC2 instances
- Databases (RDS)
- Load balancers
You control:
- IP address range (CIDR)
- Subnets
- Routing
- Security
Think of a VPC as your own private data center inside AWS.
Why Do We Need a VPC?
We need a VPC to:
- Isolate our AWS resources from others
- Control inbound and outbound traffic
- Design secure architectures
- Decide which resources are public and which are private
Without a VPC, you cannot properly secure or control your cloud infrastructure.
