What is a secluded section of the public cloud where resources can be launched in a defined virtual network called?

A secluded section of the public cloud where resources can be launched in a defined virtual network is known as a Virtual Private Cloud (VPC). This concept allows users to create their own private network within the public cloud, providing them with control over the network configuration, including IP address ranges, subnets, and firewall settings. It enhances security by allowing organizations to isolate certain workloads and resources from the rest of the public cloud environment, ensuring that sensitive data and applications can be run in a more controlled setting.

A VPC is particularly useful for organizations that need the scalability of the public cloud but require the added security and privacy that a private network provides. This capability is essential for compliance with regulatory requirements and for organizations that handle sensitive information. The other options refer to different aspects of cloud computing and do not specifically define the concept of a secluded network within a public cloud environment.
