Amazon VPC (Virtual Private Cloud) is a service that allows users to create a private network within the Amazon Web Services (AWS) cloud. This enables businesses to define their own network configuration, including IP address ranges, subnets, and route tables, providing greater control over their cloud resources. With Amazon VPC, users can securely connect their cloud resources to their on-premises data centers using a VPN (Virtual Private Network) or AWS Direct Connect. This flexibility helps organizations manage their applications and data more effectively while ensuring security and compliance with their specific requirements.
