Oracle Cloud Infrastructure Virtual Cloud Network
Oracle Cloud Infrastructure Virtual Cloud Network (VCN) is a customizable and private network in Oracle's cloud, similar to a traditional data center network. It provides complete control over IP address ranges, subnets, route tables, and gateways, enabling secure connectivity for cloud resources. VCNs allow users to isolate resources, control traffic flow, and connect to on-premises networks or the internet.
Developers should use OCI VCN when building secure, scalable applications on Oracle Cloud, as it provides foundational networking for deploying compute instances, databases, and other services. It is essential for scenarios requiring network segmentation, hybrid cloud setups, or compliance with specific security policies, offering features like security lists and network security groups for fine-grained access control.
