What is Oracle Cloud Infrastructure's networking model?

The networking model of Oracle Cloud Infrastructure (OCI) is designed around the concept of a Virtual Cloud Network (VCN) with subnets. This model allows users to create isolated networks within their cloud environment, enabling better security, organization, and management of resources.

A Virtual Cloud Network provides the flexibility to configure networking resources according to specific application needs, including establishing custom IP address ranges and creating subnets in different availability domains. Each subnet can be designated as public or private, enhancing control over security and access management. This structured approach allows for better traffic control and security policies by segregating resources based on their functional requirements.

Furthermore, the use of subnets within a VCN supports the implementation of complex network architectures, such as using multiple subnets for different tiers of an application (e.g., web, application, database) while maintaining their logical separation. This model promotes scalability, allowing organizations to expand their cloud infrastructure efficiently without compromising security or performance.

While other options suggest networking configurations, they do not accurately reflect the structured approach and features provided by OCI's networking model, which includes a robust VCN framework for managing cloud resources effectively.
