AWS Private Cloud

Amazon Virtual Private Cloud (VPC): Provision a logically isolated, customizable virtual network within the AWS Cloud.

AWS VPC delivers your own private, isolated section of the AWS Cloud: you define the network. This is your virtual data center, where you dictate the IP address range (e.g., 10.0.0.0/16), create public and private subnets across multiple Availability Zones, and configure routing tables. You maintain absolute control over the network environment, securing it with both instance-level Security Groups and subnet-level Network Access Control Lists (NACLs). For hybrid deployments, VPC integrates seamlessly with your on-premises data center via AWS Site-to-Site VPN or Direct Connect, ensuring secure, private connectivity for all your AWS resources.
