Oracle VCN provides customizable and private cloud networks in Oracle Cloud Infrastructure. Just like a traditional data center network, the VCN provides customers with complete control over their cloud networking environment. This includes assigning private IP address spaces, creating subnets and route tables, and configuring stateful firewalls. Customizable virtual networks Flexible IP assignments Customers define VCNs according to specific workload IP address requirements, and can divide a VCN into smaller ranges using private or public subnets or assign multiple IP addresses to a single VCN. Extend existing networks Extend existing on-premises networks and interconnects using virtual routers and gateways. Customers use peering gateways to connect different VCNs within a tenancy, or to connect securely to other tenancies. Site-to-site connectivity Expand your on-premises network to your Oracle Cloud VCN with a redundant VPN gateway (Site-to-Site VPN). “Bring your own” public IP addresses Bring whitelisted IP addresses or IP addresses that rely on reputation to Oracle VCNs to avoid disruptions or having to change IP addresses while migrating to Oracle Cloud. Flat cost, high-speed connectivity FastConnect allows customers to connect directly to their OCI virtual cloud network via dedicated, private, high-bandwidth connections. Then, based on the amount of data, customers simply chose an appropriate port speed and pay a consistent, low price each month. Other providers charge for the amount of data moved, which can be expensive and unpredictable.
