IBM Cloud Virtual Private Cloud (VPC)

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.

Azure Virtual Network gives you an isolated and highly-secure environment to run your virtual machines and applications. Use your private IP addresses and define subnets, access control policies, and more. Use Virtual Network to treat Azure the same as you would your own datacenter. Traffic between Azure resources in a single region, or in multiple regions, stays in the Azure network—intra-Azure traffic doesn’t flow over the Internet. In Azure, traffic for virtual machine-to-virtual machine, storage, and SQL communication only traverses the Azure network, regardless of the source and destination Azure region. Inter-region virtual network-to-virtual network traffic also flows entirely across the Azure network. Use Virtual Network to extend your on-premises IT environment into the cloud, like you set up and connect to a remote branch office. You have options to securely connect to a virtual network—choose an IPsec VPN or a private connection by using Azure ExpressRoute.
