Amazon Virtual Private Cloud

A single VPC can span multiple regions without communicating across the public internet. For on-premises, you can share a connection between VPC and on-premises resources with all regions in a single VPC. With a single VPC for an entire organization, teams can be isolated within projects, with separate billing and quotas, yet still maintain a shared private IP space and access to commonly used services. Google Cloud VPCs let you increase the IP space of any subnets without any workload shutdown or downtime. This gives you flexibility and growth options to meet your needs. VPC can automatically set up your virtual topology, configuring prefix ranges for your subnets and network policies, or you can configure your own. You can also expand CIDR ranges without downtime.

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 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. 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.Prevent attacks on customer tenancies with isolated network virtualization. A foundational element of OCI’s security-first architecture, the design stops malware with a custom-designed SmartNIC to isolate and virtualize the network.
