Amazon Virtual Private Cloud

Amazon Virtual Private Cloud (Amazon VPC) is a secure and seamless bridge between a company’s existing IT infrastructure and the AWS cloud. Amazon VPC enables enterprises to connect their existing infrastructure to a set of isolated AWS compute resources via a Virtual Private Network (VPN) connection, and to extend their existing management capabilities such as security services, firewalls, and intrusion detection systems to include their AWS resources. Amazon VPC integrates today with Amazon EC2, and will integrate with other AWS services in the future. As with all Amazon Web Services, there are no long-term contracts, minimum spend or up-front investments required. With Amazon VPC, you pay only for the resources you use.
Interesting, maybe something useful for the smaller companies
