How to Create a VPC in AWS

A Virtual Private Cloud (VPC) is the foundation of every AWS network. It lets you define your own IP ranges, create public/private subnets, attach gateways, and control traffic flow. VNet (Azure) serves a similar purpose in Azure — it’s the foundation of Azure networking, enabling communication between Azure resources, on-premises networks, and the internet. VNets define the overall address space and can be segmented into subnets. Security is managed using Network Security Groups (NSGs), which combine AWS SG and NACL functionality, and VNets support peering and VPN/ExpressRoute for hybrid connectivity. Subnets exist within a VPC or VNet and divide the network into smaller, manageable segments. Each subnet has its own IP address range (CIDR block) and can be associated with specific route tables and security rules. In AWS, subnets are AZ-specific and can be public or private depending on routing to an Internet Gateway. In Azure, subnets are not tied to physical zones but are logical div
